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?

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.
