Ok I had finally gotten done repairing my engine and it was running fine. The only thing I had left to do was tune it. Had it running great this morning now the starter doesn't do anything when I try to turn it over with the key but if I leave the key in the on position the starter tries to start by itself but it just clicks.. another issue is that the obd connector doesn't communicate with the PCM. The obd tool It connects and powers on fine but no communication. Tried three different tools. Before all this crap happened my friend accidently put the battery in backwards. While it started and ran fine for days something finally gave up today. What do you guys think it could be?
