To start this is an 05 LLY bone stock. The truck has around 50k miles and has never had a problem before. He (this is not my truck) backed it out of the garage, shut it off, then it wouldnt start. Any ideas?
To be honest I am not sure what "wouldn't start" means. Please further define the problem. Wouldn't turnover, wouldn't catch on turnover, is there any power to the radio, lights,etc? battery cable, dead battery.
A little more information would be helpful to assist in futher addressing the issue.
