I purchased a 2011 camaro it wasn't running when I did, cranks starts dies immediately. I wanted to replace engine so I took to a shop 2 weeks later I check he hasn't worked on removing it, sd they wanted to check motor he put a throttle body on it still no start , now he wants a ecu , sd get a computer from a junkyard, I heard a 2011 ecu used can't be reprogrammed js this true could this be issue with car. Starts with starting fluid dies has plenty of fuel pressure according to the shop . He sd computer has throwed every code possible
