Scotty. When I have the key on the check engine light doesn't light up. I've been reading up on that all the post I've read say it's a bad ecu. And that the car started up again as soon as they plugged in a new ecu. My question is would a new ecu need reprogramming some post i read say they do others said they dont. the problem with my car right now it cranks just fine but won't start since there is no spark it's a 95 sc400
