Will the car run? If so does everything work but the cel? Let me see if I have an extra ecu laying around with that board so I can trace the cel circuit. It may take me a few days to get to it, this is my bussy season.

Do you know that the light bulb for the CEL is good? Try a test light between ECU pin A13-green/orange wire and ground. During fuel pump prime the test light should light up. If it does, it is the bulb in the dash, if it does not, it is in the ECU.
