Thanks I ordered a used ecm it has matching part number as the one in the car hopefully it doesn't need reprogrammed, would a bad tcm cause a no crank issue

Did this work for you im considering buying a used ecm as well

Did you ever find out the problem I have same issue

I cleaned the pin connector I'm really leaning towards a bad tcm since it arcs when you add the extra ground wire, also a couple months ago the car got the power steering message I added a ground and it fixed it until now, I'm hopping I made the right troubleshooting by ordering a used tcm my next question is will the used one with a matching part number allow my car to run without being programed

did you figure out what the problem was. my cobalt is doing same thing

Umm not sure about air bag stuff, but the car ran fine drive fine it has over a quarter tank of gas. Just all of the sudden the car wouldn't start I lost my dic readouts besides odometer and it displays low fuel and power steering on the dic . And none of the gauges work. I swapped out the tcm for a used one it changed nothing if I hook a ground up to the tcm case I get very very fine Sparks I'm trying to figure out what would cause this. I'm load testing the battery tommorow at work.

i still cant figure out what the fix is for this. im having same problem plz help

Search the forum for ground location image. Chances are high, you may have one or more bad grounds.

Hey my ‘07 says power steering and low fuel lights on. It won’t start won’t crank but all the lights and everything else works. I only have the key but not the fob. Can I possibly bypass this fob system to get my car started
