[QUOTE="montesa, post: 4237829, member: 477"] Dbleak, Just want to clarify. I believe the PIP sends info to the computer. That will affect whether the injectors pulse or not and tells the ICM to power the coil. The PIP can cause intermittent issues. The computer could think the engine isn't running and not pulse the injectors or turn off the pump. This link is just good to read because it makes it easy to understand. [URL]https://easyautodiagnostics.com/ford/4.9L-5.0L-5.8L/what-does-the-pip-sensor-do[/URL] Might consider installing one of those little inline fuel pressure gauges. You could have everything right and timing could cause it to not run. You could rotate the engine by hand until the rotor lines up on cylinder one. Then just see what timing marks are lining up. I think these trucks are 12d BTDC. I've read that there is a notch at 12d. You might also be able to hear or feel if there's something weird inside the distributor. Perhaps a crusty PIP. If you got the PIP code for sure, all that means is the computer isn't receiving the proper voltage range from the PIP sensor. Also make sure the fuel pump isn't turning off after a few seconds of cranking just as a sanity check. [/QUOTE]
