I have an 08 g5 2.2 (same exact engine as cobalt) 5 speed. I had to put a new motor in and it won't crank or try to start. All fuses are good. All power and grounds are clean. Yet all accessories work just fine. Any ideas? I even tried to jump solenoid on starter

You need to get a to get a Tec II Bi-directional scanner and program your BCM or if it's a junkyard motor ask for the BCM out of the donor car that motor was in. You can also have it towed to your local GM dealer an pay & arm and a leg for a dealer to do it. Had the same problem when I built mine.

I won't pay dealer prices. I'll see if I can swap out bcms and if it works great if not I'll just sell it cause I'm tires of tinkering and putting money into it
