The accumulator must hold fuel pressure in the injector lines to ensure good hot starts. Otherwise the fuel vaporizes and the engine needs a lot of cranking to start. The second part that can cause this, as you correctly listed below, is the check valve. It allows fuel pressure to bleed off with the same results as a bad accumulator. Also, if the fuel filter isn't new, replace it too. Fuel injection has to have CLEAN fuel to function properly. You can order all of the parts you need on-line, or give us a call.
