[QUOTE="ZeroDCX, post: 15321040, member: 91953"] If sufficient fuel pressure is not met, the vehicle should not start. But there are instances where the vehicle would run roughly versus not starting. Example being, the system could pressurize enough to start the car but not enough to meet the demands of a running vehicle. Its easier to pressurize the system with no demands versus keeping adequate pressure with the engine running/consuming fuel. The system could also be rapidly losing pressure and fall below starting threshold conditions. You wouldn't know until further diagnosis is performed. Retest fuel pressure KOEO/KOER (if possible) with a good known gauge to further diagnose your issue. If it is below specs, then you've isolated your issue. Also inspect all wiring, fuses, etc. Can you hear the fuel pump prime the system when turning on the ignition? [/QUOTE]
