Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The ECM fuse can blow due to any of the following,

  • Grounded Fuel Injector Wiring
  • Grounded Torque Converter Clutch (TCC) Solenoid Wiring —TCC solenoid power wire grounded.

    In order to determine which one is at fault you are going to need to do some testing. I have enclosed the steps in the link below. Copy and paste the link to your browser to open and view it.
