I lose fuel pressure at normal driving conditions. My vehicle has new fuel pump, filter, pressure regulator, injector. I hooked an inline pressure gauge to monitor the pressure. It has a TBI set up that should be running at about 14 - 15 psi. It will start and idle fine. When you try to drive sometimes it will work fine for a while other times it happens right away, but when it happens the fuel pressure starts dropping until it stalls at about 9 psi. If you let it sit for a bit it will usually start back up and go, but shortly after that it will drop again. Please help this is driving me crazy!
have the same problem?
