Hi my name is***** will be glad to help. That fault is an indicator of an internal memory failure of the ECM (128= engine ECM). Verify power and ground to your ECM and if it tests good try a test ECM or have yours reflashed and bench tested. Replace the ECM if it fails the bench test and will not successfully take the software flash ans upgrade. Also check all your battery to starter connections for corrosion and damage and test your batteries. Let me know

Hi, Did you get this resolved?

Yea I did a shut down override and the engine lite went off and the truck cranked right up. And I haven't had any problems since. I think I need to replace either the starter or the seliod.
