So im new to the whole forum thing so I hope to find some help out there. I have a 2006 Colorado with the 2.8. My truck is having a issue with starting. I turn the key and the lights turn off and nothing happens. The truck wont start not even try. There is a red car with a pad lock going through it. I read about HPtuners but the truck has to be on to do that. What are yalls opinions???
