Re: 97' 7.3L Powerstroke/Possible IDM Failure?
I'm still somewhat green on these little "migit" diesels. I've been burying myself in Chilton and getting tips from the real guru's here on the board myself...
That said, I've been told that Maxi-fuse #8 under the hood is for the IDM (Info recieved from RSP) and that one of those two relays next to the fuseblock is also associated.

Thanx a bunch for the help Kris! Where does the IDM get its supply voltage, could I be looking at a faulty relay, fuse, circuit breaker, fuseable link, etc.? If not, I'll likely replace the CPS first and if that doesn't do the trick I'll check the wiring harness inside the engine under the valve covers and externally as well to make sure I don't have any shorts/opens/high resistance. If all that fails to yeild results I'll try and find someone with a PSD and swap the IDM before I dish out the coin for a new one.
I'm really hoping it's the CPS! LOL

If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.
