Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Have you checked the battery connections?
try doing a visual inspection of the wiring harness and look for any obvious signs of damage, and also look at any ground connections you can find and see if they are secure
let me do some digging and i will be back with you shortly
Check these 2 grounds as best as possible, make sure they are good and tight
Okay, let me know what you find.
check the pcm-b fuse. the pcm gets power from that circuit
Also check to see if that fuse is getting power
If that fuse is getting power and your grounds are good then it probably is the ecm. If that fuse isnt getting power then it is likely the fuse block itself in the engine compartment.
If you have any more questions please let me know, I will be happy to help.
I agree, if there was a short then the fuse would have blown.
I would give it a try at this point, you have checked the most common scenarios.
You are welcome!
