Ran continuity test fro IAC to the PCM. One diagram shows 29 and 29 on c2 and other shows 28 and 38. I believe 29 and 39 are right and 39 was good to terminal 1 but 29 to terminal 2 showed nothing. I ran a temporary wire from there to the pcm and still didn't change anything. Damn thing tries to run with the IAC out but when you plug it in just cranks no starts

 

bad IAC?

 

Replaced it with a new one and same deal. Now it was nasty looking and of course 12 yrs old so replacing it was ok with me. Im trying to find out what outputs I should see at the connector. Im also locating a known good used PCM. Talked to a tech today and we are thinking the PCM isn't commanding the IAC to do what is supposed to do and actually doing the exact opposite.

 

Ok so crank sensor i got was bad. Put different one in and got spark now. ASD relay seems to work now. Checking fuel injector pulses which im sure i got now as these truck will run with a crank or cam sensor down. Checked windows on the crank for the crank sensor and they looked great. Checking fuel pump relay too tonight. Long processes and not much time each night to lok at it lol. Getting there

 

keep it up man

 

Ok. Truck is running. Found it burnt the ground going to the fuel pump module as well. When the fuse box shorted im guessing it sent ground where power was supposed to go and visa versa. It burnt the fuel pump up too. Crazy. Anbyway gauges all working. Truck is running 3 days now just been busy catching up on stuff. Thanks for the help. ABS light is flashing but im guessing thats because this new computer the SKIM wasnt programmed in it.

 

HELL YES! Can you go back through and summarize what you found as you went, an overview with the particulars? Badass my man!
