Alrighty, im getting 5 volts.

I usually manually test pressure at this point. Does that first voltage drop when you stop cranking the truck? Should drop to .02v

It drops to .07, haven't seen it go any lower. My scanner won't read anything other than engine rpm and vehicle speeds.. I don't think this scanner was made for diesels, but I did a voltage check like you said, 0.14 volts when cranking. .07 volts when i stop. Seeing 5 volts from the two wires. I'm stumped on this one. Truck won't fire regardless if ICP is plugged in or not, I'm starting to think that maybe it is the IDM?
*Edit* My bad, it does drop to .02 volts, It just takes a little while. |
Not the idm this go round. You icp sensor is good. You have a high pressure oil leak, could be a bad hpop, a bad ipr, a failed injector or o-ring but the reason the truck wont start it high pressure oil.

that fuse link is more like a stud in a plastic box one wire in and two out it mounts on the inner fender well

Is there any way to test an IPR? It has 12 Volts going to it, but I can't tell if its working. Decided to try this first rather than buying a new HPOP or messing with injectors.

Sure you could check resistance across the two pins on the ipr. Should be 5-20 ohms. Check the red wire for battery voltage while cranking with it plugged in. If you've got a meter that will read duty cycle you could check the duty cycle on the yellow/red wire. You could pull it and check for damage. The ipr isn't very expensive. If you see any damage just replace it.
