Truck won't start
#12
For whatever reason, the PCM doesn't think the engine is turning. The power being there for a bit, then going away, even while the engine is turning, is a dead giveaway. Reasoning here is: If the PCM does not see the engine turning, it won't energize the ASD relay, which supplies power to the coil/injectors.
Are you actually getting five volts to the cam, and crank sensors?

SO, Good news I replaced the PCM once again and it started right up! I think the problem last time we had it in was the battery. That being said, now that it runs, the new transmission that JUST got rebuilt shifts fine EXCEPT while in gear (D,2,1), will not shift out of first. So that's a new problem we've got to fix.. Wonder whats causing that.. We noticed the trans was leaking where it joined the engine so we thought fluids may be low from leaking over a few days since we put it in, SO we filled it but no difference.
I appreciate the help btw!

So we got the transmission fixed (As far as we know) but when we went to go drive, it ran for a couple of seconds (over 30), and then it died, and we havent been able to start it since. We assumed it was a fuel problem, so my dad replaced the fuel pump; still wouldn't start. So then he went out and got ANOTHER new PCM, and it is doing exactly what it did before, keeping the fuel pump running constantly when the key is in the on position. Not sure what could be at fault this time... Any suggestions/ideas?
