It's been awhile since I worked on a 7.3 at all and I understand the 95 was a bastard year in many ways. I have a '95 E350 van here that started and ran for about half an hour then died and hasn't started since except one time with a fine mist of ether keeping it running for about 20 sec. I have a fuel pressure gauge installed and I'm seeing it pulse with each revolution of the engine (mech left pump). It pulses up to 45psi and then falls back to 40psi before it pulses again. I'm wondering if I should be seeing a steady 45psi and no leak down at all. Because of what I'm seeing I am suspect of the pressure regulator but before I tear deep into this van, because everything is hard to get to, I wanted to get opinions here. This vehicle has a correct 70k miles on it. It has a new starter just to eliminate the possibility of spinning too slow to fire the injectors as well. It has a new fuel filter and the tank is dropped so I can see fuel return going into a bottle and verified fuel is circulating and no air is coming through. It came to me as a basket case from another shop who began a 4x4 conversion but never completed it and I understand it sat parked for at least 6 months without being cranked before it came to me.
