I have been working on a 97 7.3 that you have to crank for 45-60 secs. before it will start. I have been watching the data stream while cranking and the HOP pressure only starts to come up right when it fires. I am sure something is up with the high pressure system. Question is could it be that the IPR is sticking or that the HOP is failing? Also is there anyway to test either of these?
