    I'm stuck in Virginia with my truck.
    My board has a message to check engine ecu next stop but I can't start the truck.
    One of my 30 amps fuse is blown on battery terminal. I tried replacing it but the new burned out even when the truck is off.
    Any ideas?

    You have a direct short in the main ecm harness follow the harness from the fuses to the ecm and see if you can find it

    Belive me, internal ECM damage happens too!

    So I use to separate ECM power supply connector first to be sure ECM is OK
