Harness Problem?

Since none of the other stuff on the other thread worked, according to alldata my truck has a short somewhere in the harness to the injectors, when the truck is off everything passes as soon as its cranked it comes back, my IDM and PCM is good and all the injectors have a 0% on percentage delta on my WDS System is there a common place to look what do i do from here

Look where the wires that are on top of the valve covers they have been known to chaffe from time to time. (IIRC)

What exactly are you chasing? Yes chaffed wires around the 42 pin connector over the drivers valve cover has been an issue. If there's a short between the IDM & injectors, this or the UVCH would be suspect. You can ohm the wires between the IDM and 42 pin connector, and between the 42 pin connector and the valve covers to check for continuity, but if the problem is sporadic, that will be a hard thing to trace down with an ohm meter.

when i took that connector off it had green goo in it, cleaned it and it helped but still ran poorly so i dug into it more and saw my icp going below 500 psi the blame ipr connection was loose it ran real good this morning but im still replacing the valve cover harness to get rid of the check engine light and i do have the fix from international coming to fix the valve covers for good

The green goo is corrrosion. Sometimes it shows up as a dry kinda powdery substance, and sometimes depending on the application it "gooey."
