I bought a 01 neon. That had a PCM fault in it when I bought it. It would start and run about 3 min then shutdown. Then it began to not start at all. I installed a new computer on it. It started and ran about 3 mins and shutdown and will not start. Just like to old computer did. It is not getting spark. I think it has to do with the auto shutdown relay. I swapped the relay with the horn relay but still will not start. Start checking wires but it got dark. I am wondering if anybody on here has had this problem. Or can give me some ideas.

 

ok, first question. what is the color of your key? is it grey or black. second. where did you get the new pcm.
