careldo Posted January 28, 2004 Report Share Posted January 28, 2004 Hey guys. can anyone tell me what the normal fuel pressure reading should be with the car running in idle and what it should be with key on and engine stopped on the 4.9L. I'm getting 38 PSI key on engine off and 25 PSI engine idling. thanks, careldo Link to comment Share on other sites More sharing options...
