Well they finally got it started! Supposedly it was two connectors that were the same, swapped them and it fired up. Someone had suggested the TB and Cam sensor plugs could be mixed up, I think they were the two that were.

Before I got there today, it was firing right up and running good. When I got there it would start then choke and die. I tried swapping the plug for the SCIP sensor, with the one just to the right of the intake manifold. They were the same connector and close to eachother, so I though they could have been mixed up. Well the car started right up and idled great. I then had my buddy come down with his stock SS. After looking over his connections, I saw I didn't need to swap them connectors. I went in and put them back to the way they should be. The car fired right up!?!

So as it stands now, the car fires right up and idles perfect. They were closing for the day, so I didn't get to test drive. He is going to keep it until Monday, test drive and go over everything.

Thanks for all the help everyone! I will post the outcome Monday.

 

Awesome, I'm glad I could help

 

I did a motor swap in my 06 cobalt lt 5speed , and when I turn the key on dash lights up and give the car life. When I go to crank it it does absolutely nothing. And there is no fuel pump power either... but if I jump the starter it will crank over?? What's the issue I should look for.

 

Are all the lights on the dash turning on or just a couple? I can't remember what the dash does when you need to do a security relearn but the lock icon is either on steady or blinks. If that's not it I would say your most likely culprit is in either the fuse/relay box or a bad ground.. If you jump the starter directly it will always crank over as long as the engine is free to rotate.

 

I have an 08 cobalt with a 2010 engine and transmission. Car has some cranking starting hesitation but always starts eventually. Would my car need relearned or reset in some way to sync it
