jcdickson1 Posted January 30, 2019 Share Posted January 30, 2019 I have a 93 sc400 that just had the ecu rebuilt. I put the rebuilt ecu in the car and tried to start it. It won't start up. I don't see the check engine light on the dash. Is the ecu bad? Should I try to find another ecu? Will ecu's from other model years work in my 93'?
