Why does my ecm 1 fuse keeps blowing as soon as I turn the key to the on position
I need help
It's possible that the fuse has other accessories working on it. For example, I had a Ford that the ECU and lighter shaded the same fuse.
That is not a good enough answer what is all on the ecm 1 fuse
Check ecm wires for short.If u are not starting the truck and the fuse is blowing that's where I would start
