ECM issues?
My husband and I have a 1993 40th Anniversary edition corvette. When we bought it in October whoever had it before us never put the ECM bracket back on so we don’t have it and haven’t gotten around to trying to replace it. We had it running one morning and in a rush closed the hood on the ECM.
We sent it off to be repaired and just got it back yesterday. Everything else on the car looked as good as it has since we bought it so we plugged it back in and still nothing.
we have no power to anything!
we Just replaced the optispark in October and have replaced most of the other issues on the car.
just trying to get some insight on what to try next.
codes coming up on the dash
C41, H25, H41, H72, H74
module 4 & 9 are saying Error
