Arizona Mechanical help/scanner help
I got a 5.3/4l60e that ran great in another truck with the current PCM/standalone harness. I swapped the motor in another truck, it fired up about 5 times then died while running and won't start back up. I've done everything I can think of. Checked grounds, ripped harness out and checked all wires.
I would pay someone to come to my house and hook up to it and see if they can figure out the problem. I don't have a trailer to take it somewhere plus it's a dually. Let me know if maybe you can recommend someone thanks.
