We have a 93 Stealth sohc. We replaced the ecu, at first we hadd no check engine light at all, with the key in on position. My husband fixed a wiring problem at the fuse box and car still wont start. we are thinking that it could be the MFI relay but noone has heard of it??? (We payed $500 for the car but knew it needed a ecu. Never heard it run. I love the car already and want to keep it.) Has anyone ever heard of anything like this?? Please help
