bleeds off when i shut the car off. Its really just a matter of testing each of the possible problems. I have yet to set around to it myself, but things to check that I can think of would be.... 1. fuel pump check valve 2. fuel pressure regulator 3. pinched lower o-ring on injector
Im not sure where your fuel pressure reading is coming from but I assume it is probably tapped in right after the fuel filter. If thats the case you can pressure up the system and pinch the line off after it and shut the car off. If the check valve in the fuel pump is the culprit it should read a pressure drop as the fuel flows back into the tank. If not then you can try to pinch it off before the pressure sender and see if it bleeds the pressure on the engine side of the line which leaves the injector o-rings and regulator. There may be better ways to do this but this is how I had planned to chase down my problem when i get around to it.
