Let me know how you checked for power and ground for the ECM. we need to check with a test light or multi meter to make sure we have power and that there is no voltage drop. ECM should be hot all the time on pin A(white/red wire)

black wires are the grounds. You can disconnect the ECM connector and ohm out the grounds, less than 5 ohms is good. let me know if you have a multi meter.

let me know what you find

lets start here

good luck

I have a multi-meter digital I will check them and get back to you

If we have no power or a bad ground we will not a check engine light. If power and ground is good I would suspect the ECM.
