greetings,

If the ecm1 fuse is blowing you either have high resistance in the wire harness or a failed component(ecm, injector,egr solenoid) you can try disconnecting the egr solenoid and see if it stops. For the injector or wires you will have to use a multi meter and ohm them out.graphic

good luck

ECM 1 fuse continues to blow out , oil pressure sensor has got a good ground and the wiring harness seems to be in good shape. I'am lost and don't know what to try next?

 

Expert:  ironmike replied 4 years ago.
did you check the injector?They don't recommend checking with ohm meter, but a tester most dealers had or have. They do an injector coil test.
Customer: replied 4 years ago.
