Default Re: H2 FUEL PRESSURE ISSUE?

sounds like the fuel pressure regulator is allowing the fuel prime to bleed off slowly which would be why you need to prime the system 3 times for it to start after sitting. also could be a leaky injector. Put a fuel pressure gauge on it and pressure system up with a few key cycles then watch the pressure, if it drops slowly pinch off the fuel return line. if it continues to drop, injector is leaking, if it stops dropping regulator is leaking
