      One of the basic maintenance projects that you should perform on your BMW is the replacement of the fuel filter.  I recommend that you replace your fuel filter about once a year, or ever 10,000 miles.  It seems that with today's fuels, there always seems to be some gas station that has problems with dirt or grime in the gasoline that can clog your tank.  I don't think quality control with gasoline stations is really what it used to be.  Needless to say, I try to replace all the fuel filters at least once a year.

     Changing the fuel filter is not a job that I relish.  There is an almost guarantee that you will spill at least some fuel on the ground and yourself as you swap out the fuel filter.  Perform the replacement in a well-ventilated area.  That means outdoors or in your garage with a few large fans blowing air both in and out.  Have a fire extinguisher handy, wear rubber gloves, eye protection, and have a few rolls of paper towels handy.

     The fuel tank should be as low as possible - drive around the car until the gas tank is almost empty.  This will minimize problems if something should happen to go wrong. 

     The first step is to jack the car up.  See our Pelican Technical Article on Jacking Up for more information.  I recommend that you only jack up the front of the car, and leave the rear on the ground.  This will minimize any fuel flowing forward to the front of the car from the tank.  The E36 3-Series BMWs have a semi-intelligent design when it comes to fuel flow.  The fuel pump is located in the top of the tank, and pumps fuel out the top as well.  Why is this good?  Well, when you go to change the fuel filter, you can pull out the fuel pump relay, crank the car a few times, and be assured that fuel isn't going to flow everywhere if you make a mistake.  Some cars have a gravity-fed system that takes fuel out of the bottom of the tank.  With these systems, you have to disconnect the line, and clamp it very quickly, otherwise, the entire tank of gas will empty out!

     Now, pull out the fuse for the fuel pump (Figure 1), and crank the engine a few times.  In general, this is fuse #9 on the E30 cars, and fuse #18 on the E36 cars - check your individual model first, prior to pulling the fuse.  Removing this fuse and turning over the car will help to reduce some of the fuel in the system.  Unfortunately, you can't get most of it out, and some will spill when you disconnect the fuel filter.  In addition, the filter itself will be full of fuel too.

     Now, crawl underneath the car.  The fuel filter is generally in the same location for all of the cars - located on the left side of the car, somewhat underneath the engine (Figure 2, Figure 3, and Figure 4).  Also see Figure 5 for a photo of what a brand new fuel filter should look like.  You now want to disconnect the line.  I typically like to clamp the fuel line before disconnecting it as this will minimize the amount of fuel that will leak out.  However, you have to be very careful clamping the line, otherwise you may damage it.  A large c-clamp works well, or you can use Vice-Grips, but only if you cover the jaws with several layers of duct tape - this will minimize the amount of damage you will do to the line.  It's okay to squeeze the line closed tight, but you don't want to score, rip, or crack it with your clamping tools.

     With both the inlet and the outlet to the fuel filter clamped, release the hose clamps on either side.  Have a small pail or bucket handy to catch the excess fuel when you release the line.  Sometimes the line will slip off, but some times it will require some coaxing.  I recommend using a small crescent wrench that fits nicely around the fuel pump inlet, but is too small to fit around the fuel line.  Wedge the wrench against the filter housing, and you should be able to pry off any stubborn fuel line.  If all fails, and you simply cannot pull the line off of the filter, then make a small 1/4" cut along the length of the line and try again.  Continue making cuts until you can remove the line.  This will minimize the amount of line that you will have to cut in order to get the filter off.

     When the line is released, expect quite a few ounces of gasoline to be coming your way.  Be prepared (gloves, eye protection, paper towels, bucket, and a well-ventilated area).  Take the filter out (it's held in with a hose clamp), put it in your bucket and take it, and any left over or spilled gasoline outside of your garage immediately.  Let the garage sit empty for about 15-20 minutes before you re-enter - it will take about that long for the fumes to clear.  Then, simply reattach the new filter in place of the old one.  Tighten the clamps tight, but don't clamp them so tightly that you strip the clamps.

     Well, there you have it - it's really not too difficult at all.  If you would like to see more technical articles like this one, please continue to support Pelican Parts with all your parts needs.  If you like what you see here, then please visit our online BMW catalog and help support the collection and creating of new and informative technical articles like this one.  Your continued support directly affects the expansion and existence of this site and technical articles like this one.  As always, if you have any questions or comments about this helpful article, please drop us a line.

Jai boi Comments: Hi my e46 start fine but idles at 600rpm, the engine feels like it's gonna die and it makes me bounce when I'm sat in the driver seat, it been to the garage as I was having oil leak out the oil cap and vvt sensor and now that sorted this has accused any idea what IT could be thanks.
October 10, 2014
  Followup from the Pelican Staff: Is the check engine light on? Sounds like an engine misfire. I would check spark, fuel and compression on all cylinders.

Tonic Comments: Hie,I have a 320i,when you start the engine it runs for a few seconds,failing to idle and eventually stops running. When i replaced the petrol filter its nolonger starting the engine even after a hard crank..Thanks in advance
October 10, 2014
  Followup from the Pelican Staff: I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

gremlin Comments: Hi, i have 1988 E36 Compact with 130k km on it. My fuel filter was never changed! It is BMW original with date 26.03.98 on it. I don't have any problem with this car. What should i do?
August 30, 2014
  Followup from the Pelican Staff: Replace the fuel filter. - Nick at Pelican Parts  
Mike Comments: Hey I have a 95 bmw 318i after replacing fuel pump my car one day atalled on me just lost power I would try to turn it on and it would idle for couple seconds and die so I waited a couple minutes and drove to a place I can check it there was oil on the spark plugs so I turned it on and manage to barely get it home before stalling so I switched Spark plugs and valve cover gasket so no more leaks but a week later car shut off on me checked can shaft and it had oil prolly from previous cal over leak so I replaced camshaft sendor and seal so I drove my car about 3 week and it stalled again I'm thinking now it's a fuel filter that's clogged I don't know if previous owner changed it before I got the car with 150000 miles now it's almost at 200000 also I order a after market fuel pump can that be the issue? And when I changed my fuel pump I think dirt went in the fuel tank do you think it can be the fuel filter clogged or bad fuel pump also I never changed the sending unit just the fuel pump so my car now marks different gas on the fuel gauge and work randomly
August 17, 2014
  Followup from the Pelican Staff: Why did you replace the fuel pump? Have to tested fuel pressure? I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes?

Shnips Comments: Hi, i have 328i sedan e36. After vacation when i turned the ignition on there was some kind of weird sound from fuel pump/fuel system. Like bubbling or something, different than it was before. And yesterday when i was parking it after pressing clutch and releasing gas it stalled twice. Also it feels like its not pulling as much as it did before, but not so sure... Im guessing its either fuel pump or fuel filter? More like fuel filter maybe?
August 3, 2014
  Followup from the Pelican Staff: When the key is turned ON, you should hear the pump run. If the sound has changed, the pump may be failing. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.

Dave Comments: Hi,

I have a 1987 635csi that idles normal, and when accelerating does great. However, when I'm driving at road speed I can feel a small "pulling" just briefly at various rpms as if it has a lag in the fuel line or it's starving for more fuel. I notice this mostly right before the car is going to shift automatic At a maintained speed over 40+mph, it does great. Any suggestions?

  Followup from the Pelican Staff: Sounds like an engine misfire. I would check spark, fuel and compression on all cylinders. - Nick at Pelican Parts  
Newf Comments: Not sure if it is the fuel sending unit or not...I have a 96 Z3 with 18,dismiss KMs, I store it every winter and fill it before I store it. When I first drove the vehicle this spring I noticed the fuel gauge was going from full to empty and back, I also noticed the smell of fuel in the car. I have driven it since and noticed the same. Any suggestions?
July 27, 2014
  Followup from the Pelican Staff: I would check if there is rodent damage at the sending unit. The way it is mounted, it will leak even with very little fuel in the tank. - Nick at Pelican Parts  
tattooguy24 Comments: hi
i have a 97 bmw 328is coup im having a problem the car will start just for a moment then die after i take my foot off the gas , just trying to figure out what could be the cause , a sensor, ful epump?
June 29, 2014
  Followup from the Pelican Staff: I would check for vacuum leaks to start. If an intake boot is broken, the vehicle will not want to idle. - Nick at Pelican Parts  
willie Comments: Hello there I have a 2001 i530 bmw /and at the moment the fuel intake system over flood with gas the mechanic has made me git a fuel filter spark plugs regulator has any one had any problems with this type of problem
June 24, 2014
  Followup from the Pelican Staff: How did you determine the vehicle is over-fueling? Did you check fuel pressure? - Nick at Pelican Parts  
Shirlb Comments: Hi I have a bmw 325ci sport which is fuel starved I replaced the relay and the fuel pump fuse 54 still nothing help
June 24, 2014
  Followup from the Pelican Staff: How did you determine it is fuel starved? Did you perform a fuel delivery system test. Check fuel pressure, volume and quality. What data do you have to back up the diagnosis?
- Nick at Pelican Parts
 
rizeyyy Comments: Hi Nick! Thank you for the response. May I add that the check engine light came on while trying to start the car and then it came off after I was driving on the freeway. Could this be a maintenance issue? Any thoughts?
June 23, 2014
  Followup from the Pelican Staff: No, that would be a fault that went away. However, the check engine is normally on with the key on and engine off and on when cranking. If that is the case, it is normal operation. - Nick at Pelican Parts  
Julyan Comments: Hello,

I have a 93 318i. When the car is first started is idles at about 700 rpm. If I rev is, it often drops lower and on occasion has stalled. Whilst driving the other day the car started to shudder badly, not sure if that is related. Not sure what this may be but obviously concerned by it.

rizeyyy Comments: Hi, I have a 1995 BMW 318i... whenever I start the car it struggles to start and then dies - so I step on the gas as I start it and hold it for a few minutes and it doesn't die. Also, whenever I'm at a stop light, it seems to have a rough idle. Any idea what's wrong with the struggling to start and dying issue? Would it be an expensive fix? Thanks a bunch!
June 20, 2014
  Followup from the Pelican Staff: This could be many things, from a fuel pump issue to a base engine problem. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

Msandane Comments: hi Nick thanks for the response,continuing to the yesterdays post,Yes the tank that has the pump once it get finished the car shuts off,as I Nick the other tank has about 8L there is no pressure on the pipe that feeding to that tank
June 19, 2014
  Followup from the Pelican Staff: Sounds like an issue with the siphon. Inspect the lines from one side of the tank to the other. Check for cracks or disconnected lines. If nothing is found, replace the siphon. - Nick at Pelican Parts  
msandane Comments: hi I have e36 94mdl m43 my problem is this my car when it get to a qter tank the lights doesn't comes on it shuts off as if the fuel is finish,but there is about 8litre on the other tank,i stripped off the pipe that comes from the engen I would say that because it comes underneath the car,and I discovered that ther is no fuel entering the tank ,I have change the fuel pump and the fuel filter but still no success ,pls help
June 19, 2014
  Followup from the Pelican Staff: Are you sure the tank has fuel in it? If it dies each time at the same fuel gauge level, it could be out of fuel. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
If it is faulty, check power and ground to the fuel pump when cranking the engine. - Nick at Pelican Parts
 
Cruz Comments: I have a 2011 328x drive. For some reason the car starts jerking really hard & the check engine light comes on. When i restart my car it goes off. Any idea whats wrong. It has about 29000 miles

chris Comments: so I changed out the plugs all my old ones were full of oil and the car is still acting up..
I am guessing it's a bad coil then? gonna check the fuel filter tommorow car starts fine and then idle goes down under 500 seems like its gonna stall
June 15, 2014
  Followup from the Pelican Staff: OIL on the plug is not from a bad coil. That would be from a bad seal in the engine, leaking oil into the cylinder. - Nick at Pelican Parts  
erik Comments: Bello, I have a 1987 325 and I was driving and my car just shut off. I went to start it and all it did was turn over and wouldn't start. Let it sit a hour and still wouldn't start. I then started tapping on the fuel filter which is new and had someone turn the key while I was tappi g on the filter and it started. Did this twice so far and I don't know what it could be. Any suggestions? Relay maybe?

Steve Comments: I have a 1993 bmw 325i ato trans. I took offf my fuel pump and applied a 12 volts and it works. But if connectected to the fuel hoses it will start but die in a few seconds. And it wont start back up until u waited for a few mins. Is it a fuel filter or i' m not getting enough pressure.? I put back the fuel pump and i did not connect the hoses and i saw fuel coming out from the pump
June 11, 2014
  Followup from the Pelican Staff: COuld be low pressure or volume. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
- Nick at Pelican Parts
 
Ekpez Comments: I just had my e36, 325i 994 fuel filter changed and the injector nossles changed also. When I then embark on a trip, the car develop a gear problem. It can only change from the 1 st gear to the next at 3000rpm and refuses to move from here unless the gas pedal is step hard on. And the transmission control module light comes on here. When you off the engine and restart the engine again, the car moves well again and refuses move to move when changing gear to the second at 3000rpm. Pls, Can someone tell me what is the cause of this and what to do?
June 8, 2014
  Followup from the Pelican Staff: First check the transmission fluid level to be sure it is correct. Then check the transmission ECM for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
JOSH Comments: Hi, The temp gauge needle pegged all the way into the red as soon as the ignition key is turned on without even starting the engine. I have 1997 BMW 328i. Can you tell me the possible problem and parts that I need to replace?
June 1, 2014
  Followup from the Pelican Staff: This could be a communication problem with the DME. I would check the vehicle for fault codes. If there is a communication problem, a fault code will be set. - Nick at Pelican Parts  
Doral123 Comments: BMW 330i 2003. Car lost power then stopped . Changed out intake manifold,crankshaft, fuel pump and filter. Now getting emission check engine code and getting 15 miles/gallon . Any suggestions?
May 29, 2014
  Followup from the Pelican Staff: Do you have an engine misfire? Did you check the DME for fault codes? - Nick at Pelican Parts  
Danny Comments: Hi I have 94 BMW 318i which I changed the starter and it starts fine but then now it is leaking fuel. Any suggestion?
May 14, 2014
  Followup from the Pelican Staff: Where is it leaking fuel from? Front or rear? If front, inspect the fuel lines near the intake manifold, you may have disturbed them during the start procedure. - Nick at Pelican Parts  
Monica Comments: Have a 2000 BMW 323ci I turn the key everything lights up and turns on so no power issue but when I turn the key to start nothing no turn over or anything. Problem started where it would start most of the time and occasionally would work but then it occurred more and more often until it won't start at all now. Any suggestions.
May 7, 2014
  Followup from the Pelican Staff: I would check to see if the starter is getting the start signal from the ignition switch. If so, the starter may be faulty. - Nick at Pelican Parts  
xitomdix Comments: also to the below comment when i reconnect the air mass sensor the car would cut out.
May 7, 2014
  Followup from the Pelican Staff: Thanks. got it. - Nick at Pelican Parts  
xitomdix Comments: i have a 97 e36 320i, my car was idling really funny, got to the point where it would try and cut out. i disconnected the air mass sensor and it seemed to resolve the issue, but the car sits at 1500revs now. if i dip the clutch with foot on the break it drops down.. ive ordered a new air mass sensor, could the air mass be broken?
May 7, 2014
  Followup from the Pelican Staff: Do you have a fault code for the MAF? I would check for vacuum leaks and cracked intake boot before condemning the MAF. - Nick at Pelican Parts  
slimmy Comments: Hi I have a 2001 bmw325i I have a dash light on it is an exclamation with a ridged circle, when I'm stopped it idles funny and when I start to go it has no power it smells like burning rubber after awhile running I'm scared to death to drive I'm afraid its gonna break down, what is wrong with it and how do I fix it!!!!!!!!
April 25, 2014
  Followup from the Pelican Staff: Sounds like you have fault codes stored. Likely a fault with the DME or transmission. I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
bmwrick Comments: hello have a 2000 bmw 323i starts then dies. if i spray starter fluid in it starts and run fine. idle control valve and fuel pump replaced and still same problem. once started with very little starter fluid it will start again no problems but give it a hour and i have to spra it again fires up and fine again. i held the car at 110 mph for 10 minutes and all power seems there and everything runs fine just doesnt like to start with out a little starter fluid any ideas. only code is maf sensor this shouldnt stop it from starting any help?
April 11, 2014
  Followup from the Pelican Staff: Sounds like a fuel delivery problem. Check fuel injector pulse and pressure fuel, volume and quality.

Also, I would advise against using starting fluid. It can damage your engine.- Nick at Pelican Parts
 
Jacob B. Comments: 1997 e36 318i won't start cranks and try to start with oil in cylinders but think I'm not getting fuel to the plugs. I swapped the pump and it runs when I crank. There are no fault codes and I have spark.

benji Comments: Hi I have a 99 Bmw 328ci and when I start the car it starts perfect but revs itself when ticking one only goes up like a push off a throttle but when I'm driving it so.etimes it shudders in low revs do u know what this could be??*
March 21, 2014
  Followup from the Pelican Staff: I don't understand the problem you are having. COuld you describe it better? It sounds like maybe an engine misfire. - Nick at Pelican Parts  
wwoo888 Comments: I have a 1985 E24 Euro model. I'm in California. The car was imported in 1985 and tuned/modified to meet all Federal DOT/EPA & CA emissions standards by the original owner. I'm the 3rd owner. It just passed 200K miles.

Recently, within the past month or so, I've noticed that when I fill up gas, after I park and come back later, there's noticeable gas smell / fumes, and wet spot on ground near gas tank area. Then, a couple of times, I've actually seen gas dripping/leaking out.

When I take off gas cap, there's a very noticeable **LOUD WHOOSHING** sound, like pressure escaping or being let out.

I'm pretty sure there's no cracks or leaks in the main tank itself because after I've driven it say about 50+ miles which by then means the gas level has gone down enough, there's no more problems. It only seems to leak from the top of the filler neck / gas cap area. BTW, the gas mileage is pretty bad - probably only about 16 MPG max.

After doing some Googling on what I've described above, I've come to the conclusion / guessing that the problem may be a combination of needing a new fuel pressure regulator and also a new activated charcoal cannister. And then, just today, looking under the car, I noticed that the wire from the oxygen sensor has apparently come loose at the connection end and was dragging on the ground. Obviously, need a new O2 sensor also. What do you think?
March 16, 2014
  Followup from the Pelican Staff: Before you dig too deep. I would confirm that the tank vent hose is clear. It will be a large vacuum (rubber) hose that runs out of the charcoal canister. if plugged, it can cause this issue. - Nick at Pelican Parts  
DolanR Comments: I filled up with gas and about 200 yards after I drove away from the gas station my 2001 325i Sport started sputtering and losing power. When I started the car at the pump it started normal like its always done instantly and revs stable around 700rpm. Then when I stopped it felt like the car was about to die at any min, idling very rough. The check engine light came on about 3 mins later. I drove home about 3 miles away and on the interstate doing 65 at about 2000rpm it ran fine except for a low vibration coming from the rear of the car. Then at stop signs and red lights it would sputter again. The engine was shaking almost like it was starved of fuel. I'm no mechanic but it seems like I got some bad gas. I've added Heet water removal to the gas but didn't do much. Next I've ordered a new fuel filter ...waiting for it to be delivered. Would this solve my problem or is there a bigger issue?
March 4, 2014
  Followup from the Pelican Staff: Heet won't do much, If you have bad gas, you will have to drain the fuel and clean the tank. I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

Kierstin Comments: I have a 1997 BMW 328i. It has a very rough idle at all times of the day and doesn't matter if it's cold or warm out. It also smells of fuel inside the car very badly. It's overwhelming. It's a 5 speed manual. It is also starting to stall when at a complete stop, even if the clutch is in.
March 4, 2014
  Followup from the Pelican Staff: Sounds like you have an engine misfire, Star by checking for fault codes. Then isolate the cylinder with the misfire and repair the cause, whether is be spark, fuel or compression. - Nick at Pelican Parts  
Luis U Comments: Hi, I have a BMW 325i 2001 I ran out gas and the fuel pump went bad. I replace the fuel pump, and there was the issue occurred. When I step the gas pedal all the way down it looses power and start to shake want to shut down, but doesn't. I restart the car and back to normal.going in the freeway 70-80 looses power and loud noise in the rear every time I step on the gas.replace spark plugs, valve gasket oil was going in the spark plugs, fuel pump.no check engine light. Could it be a clog fuel filter due to running out of gas?
February 28, 2014
  Followup from the Pelican Staff: Sounds like fuel volume is dropping. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
- Nick at Pelican Parts

Nad Comments: Hi, i got BMW 325i 2003 sport with rims 225/40R18. the car is consuming fuel too much. it makes about 14MPG. i want to know what are the possibility reasons for that
February 27, 2014
  Followup from the Pelican Staff: Could have a leaking fuel injector or a component in the engine causing a (false) lean condition, causing the DME to add fuel to the mixture. - Nick at Pelican Parts  
TomB Comments: I have a 2007 E90 328XI that runs fine and everything but if i drive for about 30 minutes it rough idles only when im stopped but doesn't die. Any idea what that could be? I was thinking the fuel filter now. It throws Vanos intake code which i replaced. It didnt work I also replaced the cam shaft sensor. Also where would the fuel filter be located??
February 20, 2014
  Followup from the Pelican Staff: Unlikely it is a filter. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. You could have a VANOS fault or throttle / idle issue. The fault code will be a big help.

GUPTA THALI Comments: JUST REPLACED HEAD GASKET ,THIS VEHICLE IS OVER FUELING. WHAT CAUSING THAT?
February 20, 2014
  Followup from the Pelican Staff: I would check fuel pressure first. Then mechanical engine timing. - Nick at Pelican Parts  
Jdmky Comments: I am looking at buying an 89 335i and it idles fine all day but has fuel cut and sputters losing power when driving. The exhaust is also very loud and believe it is rusted. I believe the owner said the fuel pump had been replaced. What could be causing this?

Travis Comments: I'm looking at a 97 528i. I'll copy and paste the ad: "HE HIT A DEER AND DENTED THE FRONT HOOD. MY SON GOT HOME AND IT DIED...LIKE IT RAN OUT OF GAS. SEVERAL PEOPLE TOLD ME THAT THERE'S A MODULE SOMEWHERE THAT SHUTS DOWN THE FUEL PUMP WHEN YOU HAVE A COLLISION. I'M NOT A MECHANIC SO I REALLY DON'T KNOW. IF YOU PUT STARTING FLUID IN IT IT STARTS RIGHT UP BUT DIES WHEN THE STARTING FLUID RUNS OUT." Is this seem like an easy fix to get the fuel pump got again? If so, the price is fantastic.

Andy Comments: Hello, I have a
325I Automatic w/Steptronic trans. It started idling very, rough then loses power and dies. I can start it back up after a cpl. of tries but does the same thing. My car has about 130k miles on it. Normally runs great and is extremely reliable! Can you let me know what you think this might be and also a rough estimate on what it might cost me? Thanks so much! Andy

milo Comments: I have a 2000 BMW 740i and I drove it from Houston to New Orleans with no problems, I spent a night in New Orleans and the next morning when I started the car it started but was making a small rattling noise in idle, the noise intensified a little as I accelerated but when i got on the highway it went away. I got on i-10 from New Orleans and was driving to Pensacola, Fl but before i made it to Mobile, AL the car started to slow down i went from going 80MPH to the engine only allowing 60MPH with the accelerator all the way to the floor, it finally died and i couldn't accelerate anymore. I tried to start the car and it sounds like it wants to crank it just continues to try to turn over but it won't turn over.
January 29, 2014
  Followup from the Pelican Staff: This could be anything from a mechanical engine failure to a broken catalyst restricting the exhaust. I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

Brian Comments: I have a 325i 2002. I have a problem with coldstart. It seems like the engine is not getting enough fuel. During winter it gets worse. During summer it goes away. Four years ago I've changed the fuel pump. Also I have changed the fuel filter. Haven't done anything since. Couple of months ago once the engine gets warm up it seems like the engine is getting enough fuel at it calms down. However now even after driving for a while the problem does not go away.
December 7, 2013
  Followup from the Pelican Staff: I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

Trelliot Comments: Hi, I have a 1979 BMW 320i and it ran out of fuel in my driveway. I put a few gallons of gas in it and it started up again just fine and I parked it in my garage for the rest of the day. However, in the morning when I tried to start it up again it wouldn't. Would this more likely be a fuel filter or fuel pump problem or something else?
October 31, 2013
  Followup from the Pelican Staff: I would check to see why it doesn't start, fuel pressure , spark and so on. I could be just air in the fuel filter.

October 28, 2013
  Followup from the Pelican Staff: usually I replace mine when it is due. However, if you suspect it to be bad, you could check fuel pressure, volume and quality. If volume is low, it may due to a restricted fuel filter. Easiest teat may be to replace it. - Nick at Pelican Parts  
loveMpower Comments: I am experiencing a strong fuel odour after driving in my '85 e24 M6 and upon checking have noticed fuel leaking out of the vent pipe underneath the RH rear just in front of the rear axle, since this ocurrence the car is now reluctant to start, it will fire up but needs several cranks.
October 23, 2013
  Followup from the Pelican Staff: Check under the car for a fuel leak there should be a filter and lines right where you are seeing gas leaking.

mpm Comments: '98 323i -raw gas in intake system/throttle body while cranking -Fuel pressure @ 2.5 bar at rail while cranking -Removed fuel pump fuse and car will run until it burns off the fuel; refit fuse while running -engine immediately floods -I'm in limbo for a defective DME causing injectors to stay open -any other ideas?
September 18, 2013
  Followup from the Pelican Staff: Check the fuel pressure regulator and see if it is leaking. Also unplug the injectors and see if any of them have power and ground at the connector, if so start looking for a short in the harness or a DME. Remove the injector rail and check to see if the injectors are leaking.

tj Comments: 1993 BMW 740 I was running fine one day sorry running horrible the next. it's getting no power and it's making a little popping noise like little mini backfires when you give it gas. when the car is in park and you get up to 3000 rpms it starts cutting in and out and the check engine light flashes. to be crankshaft position sensor
September 16, 2013
  Followup from the Pelican Staff: If you have a fault for the crank sensor, I would replace it, also measure the fuel pressure and volume, it if low it will cause the engine to not run correctly. The fuel pressure should be about 52 psi at idle, and the volume should be about 1L per 30 seconds.

jo Comments: i have bmx5 when gaz tank is low ,the car cheak and shut off while driving
September 16, 2013
  Followup from the Pelican Staff: You could have a problem with the siphon jet pump in the tank. You could also have a problem with the return fuel pressure being low. That could be the filter or the regulator. Or you could be just low on fuel.

Allen Comments: Hello was driving on the interstate heading home when my 2003 BMW 325i would not take gas no matter how hard I pushed the peddle, so when I went to turn off the car completely stooped running shut off I tried to crank it - it would crank but not stay running. Could it be the filter or the pump?
August 25, 2013
  Followup from the Pelican Staff: This could be a filter or a pump. I would perform a fuel delivery system test. Check fuel pressure, volume and quality. If there is no pressure, check that the pump has good power and ground. If it does and it is not activating, the pump is faulty. - Nick at Pelican Parts

I would like to attempt to fix this problem myself as I am a 64 year old guy with very little financial resources if you could just talk me though the problem I would really appreciate it. I have worked on a.number of cars in the past 50 year, Many thanks I am relying on you for some advice Nick, Regards from Don August 4 2013
August 6, 2013
  Followup from the Pelican Staff: Unfortunately I cannot dedicate too much time to one issue. Your problem sounds like it could be an engine misfire. I would do some research if I were you, on how to pinpoint and diagnose an engine misfire. You will need test equipment and a likely a BMW Scan tool. Which limits what you can do without some professional help. - Nick at Pelican Parts  
Don Comments: Hi I have a2003 318i it starts perfectly it idles ok for a few minutes then drops to about 800 rpm I think as I am not to familiar with the rev counter I am not a mechanic when I drive the car it will not pick up rev,s in all 4 gears it is very frustrating. Please give me some advice as to what I should check for on this problem. Many thanks Don.
August 4, 2013
  Followup from the Pelican Staff: if it won't accelerate, you could have a fuel delivery or volumetric efficiency issue. If you are not experienced with thtese things, I would have a mechanic diagnose it. This could save you time and money. - Nick at Pelican Parts

Papatzin Comments: I have an E36 '95 but I ran out of gas, When I felt that my car
Wont accelerate anymore i stopped it and put 3gals of gas, just
To drive my car to the gas station... I put one bottle of fuel system cleaner
And fill 3/4 of my tank with gas...well my car starts without a problem
But I feel it with no power, like hesitates when I step on it :
Some friends told me that could be dirt either in the filter and the
Injectors.... Any idea????

feeling blonde Comments: I have a small dripping of fuel coming from a hose that I thought might be going into the fuel filter, the problem is this drip in in the back of the car on the right side, down below the fuel neck. I can see exactly where it is leaking from. where is the fuel filter located on my 1990 525i BMW
July 18, 2013
  Followup from the Pelican Staff: - It should be located just before the fuel tank on the passenger side.  
Larry Comments: Hi. I need to replace the throttle position sensor on my BMW E36 320i M50 non vanos DME 3.1 Whats the difficulty rating and procedure for a DIY job? I already have the replacement sensor
July 8, 2013
  Followup from the Pelican Staff: The TPS is bolted directly to the throttle bore. You may have to remove the whole throttle bore to make it easier and if you do you should replace the gasket. - Nick at Pelican Parts  
Brad Comments: Ok so I went and bought a crankshaft position sensor and put it in last night - the car is running perfectly again. I found the job to be more difficult than expected. To access the sensor, I had to remove the expansion coolant bottle and associated piping. If my arms had been any thicker, I would have had to remove the inlet manifold too in order to access the socket where the sensor plugs in. I removed the top of the oil filter cover to give me a a bit more space to reach in under the manifold to access the plug. This required some patience! The fuel filter replacement took about 20 minutes, while the sensor replacement took about 3 hours, but now that I know what I am doing, it could take half that. Cheers

Brad Comments: My 328i began something new this week. It wont start once its hot, and lacks power. I replaced the fuel pump as it seemed to me when I compared the pressure of the old to the new one, the new one had more power. The car did start with the new one while hot, but not easily. I am thinking that I need to replace the fuel filter. Can heat cause a faulty fuel filter to fail. One last question, it seems from forums that the crank shaft and cam shaft position sensors could also be at fault. If they were faulty, would I not get a fault code on the OBC? I dont want to go buy these sensors if its not necesaary.

oops Its an e36 1998 328i
June 26, 2013
  Followup from the Pelican Staff: A fuel filter should not fail due to heat. However, restricted a fuel filter could cause a hard start at any temperature.

If you suspect a sensor is faulty and do not want to replace good parts, you will want to test them when the fault is present.- Nick at Pelican Parts
 
bushbi Comments: I have a 93 e36 325i convertible that won't start there's no power going to the fuel pump but its been tested and works and there's no power to the ecu also the dma relay looks a bit burned out could this be the problem?

May 8, 2013
  Followup from the Pelican Staff: Just to clarify, the vehicle runs normal, you place it in gear, there is a loud thump and the engine stalls? If this si the case, your torque converter could be locked up, causding the engine to stall when placed in gear. - Nick at Pelican Parts

  Followup from the Pelican Staff: It could be a number of things. If your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume and quality. Once you figure out what is missing, it will be easier to diagnose. - Nick at Pelican Parts  
benz tech Comments: We're looking for the fuel filter location on a 2002 325i m54, thank you
September 28, 2011
  Followup from the Pelican Staff: The fuel filter is located under the driver side floor, behind a cover. See this tech article: http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E46/18-FUEL-Fuel_Filter_Replacement/18-FUEL-Fuel_Filter_Replacement.htm - Nick at Pelican Parts  
Gili Comments: I have a 325CI. Ran out of gas, got it filled, thank goodness for nice people. Anyway next morning went to go to work and would not start. Turns over great, but seems like it getting no gas. Any suggestions.

Scott Comments: .. I have a 1999 E36 328iSE Touring. Engine usually runs perfect until recently when it stopped suddenly. Started again fine but it run a little lazy with an occasional misfire. All performance lost. I figured it runs fine from cold but only would lose power and perfomance when it reached full temp. I cleaned out the ICV which was full of black soot, replaced the rubber air intake which was split, .. then followed instructionos on this site to remove 02 sensors, which I cleaned with carb cleaner. they seemed clean anyway. Car run perfect again after that, however, after extensive drive testing, it misfired again and lost power. Started again fine but I'm expecting it to happen again. - I wonder how long it takes for the ECU to learn and catch up with the fixes we make? - I'll try this fuel filter fix and hope this solves it completely... *Love this site!*

  Followup from the Pelican Staff: You should not clean oxygen sensors, this could damage or contaminate them. The DME should pick up on changes immediately, clearing the adaptations or fault codes can speed this process. The key here is to find the route cause of the misfire. Do your best by pinpointing shich cylinder is the problem, then check spark, fuel and compression on that cylinder.- Nick at Pelican Parts  
James Comments: @Alex with 318ti: try unplugging the main throttle position sensor closest to the intake manifold. If the car car stops idling high, your ICV is stuck. Happened to my 328i.

  Followup from the Pelican Staff: Check fuel pressure, volume and quality. If that is OK you might have an exhuast backpressure problem. - Nick at Pelican Parts  
vic Comments: I ran out of gas in my 1979 bmw528, after adding two gallons of gas it would not start, then bringing up the fuel to half tank it still would not start, I was told to purge the injector where and how do I do that please help?
_
August 11, 2011
  Followup from the Pelican Staff: The fuel injectors will purge during engine cranking, there is no additional step required. I would check fuel pressure, volume and quality. The fuel pump may have failed from running it low. - Nick at Pelican Parts  
david Comments: i have a 95 bmw 318i manual car and i ran out of gas while i was driving to work. i thought if i just went and got some gas it would be fine. I got some gas in it and it just continued to die. i need help whats the problem.

Alex Comments: 1995 318ti 5-speed...135,xxx miles.

About 50% of the time the car will have a very high idle. Somewhere between 1600-2300rpms. It will drop down sometimes if I blast the A/C. If I hit the gas while it is idling high, the car will choke up, but then resume acceleration. Its almost like a stutter.

If I shut the car off while it is idling high, it will have trouble starting. I can smell gas when I am trying to crank it over and get it to start.

I have been getting poor gas mileage, and the idle is typically not steady.

Anybody have an idea what could be causing this? I am thinking I should replace the O2 sensor, TPS, and maybe the idle control unit. I wante dot check here with you guys first.
July 19, 2011
  Followup from the Pelican Staff: Sounds like ap roblem with the idle control cicruit. Check that there are no vacuum leaks, then check operation of the idle control valve.

Pat Comments: My 1999 528i just had the fuel filter replaced a few weeks ago. Yesterday the car died and needs a new fuel pump. Is this something that the mechanic could have predicted or prevented or even caused?
July 6, 2011
  Followup from the Pelican Staff: This is likely a coincidence.

There are tests to run to check the condition of a fuel pump. Always easier in hindsight. Without being asked, he may not considering offering the extra services due to increased cost to you. - Nick at Pelican Parts
 
B-rad Comments: Hi guys, my buddy has a 1993 740i BMW and he acted like it didn't want to run one day when he turned it on. Then it finally just wouldn't start. Replaced the dual fuel filter and it started up, well when we shut it off for 20 mins or so and tried starting it back up it wouldn't turn over. I unhooked the hoses from the fuel filter to see if the pump was still kicking on and no gas came out. But when by passing the fuel pump to make sure it worked it came on but still wouldn't start. Checked the fuel relay and it was fine along with the crankcase sensor. Can any body tell me if it may be the cutoff switch to the fuel pump or what it may be. Thanks
May 10, 2011
  Followup from the Pelican Staff: The fuel pressure should be checked with a fuel pressure gauge because the pump may not be able to deliver under pressure. If there is no fuel pressure the next step is to check for power and ground at the pump with a volt meter. If there is no power or ground refer to a wire diagram for the next test.- Nick at Pelican Parts  
jason Comments: i have a 1994 325i with the 2.5 the car ran fine then i let it sit for a few days now when i start it the car spits and sputters feels like its only running on half 3 cylinders and will not go over 40 can anyone help??

December 28, 2010
  Followup from the Pelican Staff: Your car should be able to tell you if there is a bad sensor or a problem with the fuel injection system. Take a look at my article on reading fuel injection codes, and that should give you a clue as to what the issue may be.

Kirk Comments: Ok, I have a 1999 328i with the Dinon Performance upgrade. Recently the check engine light came on while I was driving in town. It still runs but it seems like it has lost a lot of its power. It doesn't really seem to be cutting out or mising, just don't have the "pep" it use to. So, I ask, if the fuel filter is clogged, can that cause the check engine light to come on? Thanks for your advice and time!

Michael hondrix Comments: Running these engines low on fuel can damage the catalyst.
August 18, 2010
  Followup from the Pelican Staff: The Subarus used to have a warning in their manual about running the cars low on gas and how it could damage the converter due to misfires happening. But this was traced back to a sump in the bottom of the tank and a one-way valve that didn't exactly function as it should. The tank would sporadically suck fuel out the bottom and then allow air in, which would cause misfires. Repeated misfires can indeed cause damage to your CATs as raw fuel is dumped in there and then ignites in the CAT instead of the combustion chamber. However, I don't think this condition exists on the E36 BMWs. - Wayne at Pelican Parts  
Big AL Comments: dear friends of fellow bmw i too was having problems with my m3 no fuel to my injectors or current to my relay i was frustrated i tried everything,then i took off the back seat and banged on the top of the fuel pumps and guess what ? the fuel pump started to work again
June 5, 2010
  Followup from the Pelican Staff: That is a sign of a bad commuter bar in the pump. I would replace your fuel pump as soon as possible. Otherwise it may leave you stranded. - Nick at Pelican Parts  
Dave Comments: 1992 e36 here, just finished with this, thanks for the writeup. I'd like to add that in some of the early e36's there's a large metal clip not a hose clamp that holds in the filter. You can undo it from the bottom - reach around and find it, I managed to get it loosened with a small socket wrench and a long 10mm.

Definitely not one of my favorite jobs, but it's doable with a little work.

jfredrick Comments: I have a 2000 BMW 323ci. When I first start the car in the morning it runs fine, but when I turn off the ignition, and go to start it again a short time later it will start fine, but when I come to the first stop it dies. Then when I turn the key it cranks a couple of times and starts, and then it runs fine. It stopped doing this after I had the fuel system cleaned, but it started doing it again a couple of weeks later. No one seems to have any idea what is causing this...could it be the fuel filter needs to be replaced? Any help you could give would be appreciated. Thank you!
May 14, 2010
  Followup from the Pelican Staff: Sounds like it may be a clog somewhere in the fuel system. These things are very difficult to track down. I would indeed start first with the fuel filter and then go from there down the line, checking each component in the fuel system. There may be a clog in one or more injectors too. - Wayne at Pelican Parts  
Sandra Comments: I just had a tuneup. Plugs and oil, oil filter done first. Few days later had fuel filter changed. It's a 94 BMW 740I.. Well after the fuel filter was changes I went to put gas in it. And it would not start back up...

mike Comments: Steve & Calvin: Exactly my symptoms. On the highway in California bumper-to-bumper traffic @80mph, the "Check Engine" light came on. Within 30 seconds, all warning lights lit up, and the engine died. Managed to coast to side of road, thru 3 lanes of traffic. Called AAA, but then got car to restart and ran great, at least to get me a mile down the road near the closest exit, where it died again.

By waiting 3-5-10 minutes each time, I was able to start & run for progressively shorter distances, to at least get off the highway to a gas station before the tow showed up.

Thinking it was bad gas or vapor lock on unusually warm spring day, I filled the tank. That's going to be a problem with this proposed fix.

Thanks for the help, Wayne. PelicanParts, the "101 Projects" book, and this site are invaluable.

February 3, 2010
  Followup from the Pelican Staff: Give our parts specialists a call: 1-888-280-7799 They will help you find the right hose. - Nick at Pelican Parts  
Steve Comments: Calvin, I dropped the car off at the mechanic and he said the same thing and what your's said. That the relay is not getting power, they bypassed it entirely and the fuel pump is not getting power. Any luck on your end?

On a positive note, the new fuel filter went in perfectly. Relatively easy to install. You do have to unscrew the top hose from the engine compartment by accessing it from between the front tire and the steering wheel.
January 29, 2010
  Followup from the Pelican Staff: The fuel pump gets power through fuse 18 via the fuel pump relay. The fuel pump relau gets power from the DME relay. If one of these pieces is missing, the fuel pump will not get power. Start at the fuse and work your way toward the DME relay. - Nick at Pelican Parts  
Calvin Comments: Hey steve i had the same problem, just yesterday! my car shut off while on the highway doing about 50, same exact problem, i eventually started it again, then a couple hours later it stopped again. it hasnt started since, i got it towed to my mechanic and had the fuel filter changed. he said my filter was clogged but not the propblem. he said there is no current going to my fuel pump, or some other things. The current isnt even going to the relay. so something has gone wrong at the ecu. i'm very worried. I'll keep you posted on repairs.

Steve Comments: My engine turned off while driving on the freeway the other day. 1/3-1/4 of a tank of fuel. I was doing about 70, noticed my rpms drop to 0, then I had no power, then the batter and oil lights came on, power steering died. I coasted off the freeway and parked the car. Initially it wouldn't start, just kept cranking. Let it sit 5-10 min while calling a tow, tried it again and it started back up and idled for about 30 seconds before it rough idled. This sounds like the fuel filter, right? If it were the fuel pump it wouldn't have started again, would it?
January 24, 2010
  Followup from the Pelican Staff: The heat from the engine can warm the fuel rail and build enough pressure to fire the engine. The fuel pressure should be checked at the fuel rail. If the fuel pressure is found to be missing test for pressure at the pump. If this is missing test for power and ground at the pump. - Nick at Pelican Parts  
doggy Comments: i have a bmw e36 328i unfortunately i ran the fuel low the other day and now the car only seems to be running on 4 or 5 cylinders. i am guessing i have got some dirt from the tank into the fuel filter or the injectors, has anyone got any ideas on the best way to deal with this. thankyou for your time
September 6, 2009
  Followup from the Pelican Staff: it is not likely that dirt caused this as there is a fine screen on the fuel pump and a fuel filter before the fuel gets to the injectors. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

VADER Comments: Hello,

I have a 1995 E36 M50 325is, A week ago my baby shut off on me while I was driving. I immediately checked the codes with my code reader that I keep handy at all times. It gave me codes for the Crank Shaft Position Sensor and the O2 Sensor. I bought both Sensor's. I have installed the Crank Shaft Sensor first since the O2 Sensor would not stop the car from starting or running. I also, checked the fuel pump fuse and I replaced the fuel filter and Fuel Pump Relay while I was at it.

When I was done I Tried to start it and the car still would not start!!! I can hear the Fuel Pump noise "Hum-mm" when I turn the key, but it just Cranks without starting!!! What could be the issue?
August 24, 2009
  Followup from the Pelican Staff: Reset the codes, and then check again. If there is still a reading for the crank sensor, then chances are that the wire harness may be bad. Unplug the DME and check the harness with a voltmeter to see if you have continuity. - Wayne at Pelican Parts  
jt323i Comments: I have a 1985 E30 318i coupe with manual transmission. Could you be a bit more specific in reference to removing the clamps at the top of the fuel filter hose. It look as though if I just use pliers or a wrench, I will damage the clips. Is ther a special tool that I can purchase?
August 19, 2009
  Followup from the Pelican Staff: If you have pinch clamps or non-screw clamps, then you should replace them with the ones in the photos anyways. The factory used clamps that were cheap and easy to use on the assembly line - the clamps in the photos are upgrades. - Wayne at Pelican Parts  
TomM Comments: Hi, I have a 1998 E36 TDI touring wagon in Ukraine. My friend says that there is crack in the plastic fuel filter close to where the fuel line come in. I have not found a picture of a diesel fuel filter in your site and I'm wondering what they are talking about since the gas fuel filters are made from metal. I have a manual in English here but it doesn't show the fuel filter on a diesel. It seems that in this country we don't know their diesel engines very well because there is little information and less pictures about them.
May 16, 2009
  Followup from the Pelican Staff: We didn't have those vehicles here. You are going to have to go to BMW and source the info and parts from them. - Nick at Pelican Parts
