It's got to be another sensor or a fuse for it. From my experience a bad sensor will keep it from turning over. Wouldn't it be completely dead if the ECU was shot?

it does turn over. It just cranks and cranks.

I comepletly ripped intot the wiring through the jeep came up emtpy handed. the other day i beat the hell out of the PDC and then. BAM i had lights and the jeep started . although it only ran for 5-10mins before it shut off. then today went back out there to start it ran it then it died after 10mins. and now im right back where i started. NO dummy lights and communiication with the ECM no spark no fuel.

Im on ythat idea where thr ASD is being tripped and shutting everything off on me, which is also turning off the ECM.
