[QUOTE="13fist, post: 1533614, member: 31010"] It certainly sounds like you located a possible cause, shorting to ground, in the harness. It is odd that it would buzz test with this kind of short. This is the very thing that should show up during the test. Check everything in the fuse box under the hood, if you haven't already. I don't have diagrams handy at with me at work, but I'm thinking there is a diode or the like between the IDM & PCM. The reason to check the orings is for oil pressure. I think it's 500 psi it needs to see or the truck wont start. Which could also be ICP. Not sure how your seeing 2800psi with no start, I believe that's the default the PCM throws out with the ICP failed or disconnected so I'd be looking at that too. [/QUOTE]
