Thank you for that information sir.

What were powers you checked going into the ECU?

Expert:  AMEDEE replied 7 days ago.

Hello sir? Where did you go?

Customer: replied 7 days ago.
Sorry I am not at work now,used wiring schematic from Mitchell don't have the PIN numbers in front of me but we checked all power and grounds by the diagram
Expert:  AMEDEE replied 7 days ago.

Got it thanks!

If your sure you checked all powers and all grounds going into the PCM and they all check out good, the Vref is not getting shorted out and the ECU is not getting shorted out by another modules on board the vehicle, the ECU is bad and will need to be replaced.

Customer: replied 7 days ago.
That is what I figured just totally baffled what caused it
Expert:  AMEDEE replied 7 days ago.

If the wiring and other modules are good, then it would simply just be a faulty ECU. Nothing caused it to go bad. It just happened to go bad at the same time this work was done to the vehicle.
