Auto Start
 

I purchased an 09 traverse. It has many extra options but the one I was most excited about was the keyless start. The previous owner had lost the fobs and never had them replaced. I just received my replacement fobs in the mail and programmed them. They work, kind of. The car locks and unlocks and the remote start starts it. The problem is that it dies with in about 5 seconds of starting. Any ideas on how to fix this? Thank you.
