    Can anyone confirm if they are the same? I have a no start condition in my 3v f100. The diagrams I found by searching and the diagrams I bought from alldatadiy have discrepancies....some large ones. If you have a copy please let me know!

    I guess it worth mentioning that my root issue is no injector pulse. With my pats deleted tune the injectors will slightly flicker a signal and fire the engine on the second crank. But only for a few seconds because the injectors just dump fuel in on the couple times they get pulsed and stop. I’ve viewed this on my graphing multimeter.
    This doesn’t happen at all with the tune returned to stock. I only have two codes and they are related to the pcm power relay (which is one of the discrepancies in the diagrams and injector related pins)
