Just got a fuel pressure gauge, started the jeep and it went to about 62 and stayed there, shut it down and the pressure dropped to about 32, then in less than an hour to 0. I suspect the fuel filter/pressure regulator is bad. (ac delco gold) Just ordered a mopar brand to replace it. Anyone have other thoughts. (has a new fuel pump - delphi ) The rig is starting to be a hard starter, and starts faster if I stand on the floor pedal... flooding issue ??

 

Might as well add leaky/damaged fuel injectors O-rings to the list of possibilities.....
