I have a 1997 avenger and I currently have no spark and no fuel pressure. I replaced the relays (asd and fuel relay) but still no start. I ran my codes and my I/m readiness is all blank or disabled or N/a and I don't know what could be causing it!!! My only idea left is faulty ecu or pcm but I don't want to buy something that expensive if it's not the problem. Any ideas would help
