Rework Procedure

Repair
-If the harness is close to the valve spring, adjust the harness by disconnecting the injector connector rotating the connector 360 degrees and reconnecting it. This should slightly twist the wires and pull them away from the springs.

Injector Harness Replacement (If Necessary)
-If the injector harness has contacted the spring and cut the wire or exposed the wire, then replace the injector harness that is under the valve cover.
-When installing the new harness to the valve cover base make sure the tabs do not turn while torquing down the bolts(see the picture below). Keep the tabs straight, and this will help keep the wiring away from the valve springs.
