Nope. Oil in the icp. Means it's bad. They are only like $140.
To test this I can unplug the ICP? I thought I read that somewhere. Regardless i'm going to get a new one but wanted to confirm the test.

Correct. Unplug it and the computer default to 2500ish psi. Then it will try to start.

so I also bought an IPR. Should I replace the IPR as well? Accidental purchase.

I'm having a no start issue as well. I have no smoke coming out of pipe and I have changed the ICP, IPR valve, PCM, IDM, CPS, and the fuel pump. The UVCH looks fine no chaffing or bad wires but I don't understand what else I can do. The only code I have is a P1283.(IPR high circuit) Any help or advice would be greatly appreciated

welcome to the forum! you'd likely get more vies of you start a new thread ... but to start you off, do you have a monitor or scanner to check for (1) engine codes, and (2) engine parms like ICP psi values and IPR% values?

Maybe you could help me my 98 7.3 is doing my head in. Occasionally it will start and run and then just die like the key is turned off. Have tried swapping basically every sensor from another truck including idm and pcm. Purchased a AE scanner and it passes a buzz test and everything seems ok with ipr% and oil psi at injectors. When I run a koeo or koer (on the occasions it does start) it gets half way through the test and and the engine dies and scanner says unknown error same goes for koeo test. Have pulled injectors and shimmed poppets and replaced o rings. I will add that there is a enormous amount of blowby so assuming got a hole in piston or something but I don’t wanna rebuild the bastard until I can fix this problem!

TEE5 and ALF6 Ive also tried a TDE0 that was known to be good just the overdrive doesnt work, and it too will not perform a buzz test. Yes only in this truck, like i said its been tested in several other trucks and works great. ive been through the harness at least a dozen times looking for breaks or cuts and cant find any. this truck has been built from the ground up so ive touched every plug and bolt on this thing and cant find a reason for it to act like this. if i can figure out why the auto pcms wont allow a buzz test, ill be in good shape.
Re check valve cover injector and glow plug harness if new I had a few that the factory zip ties where pulling to hard and causing a short at the plug between terminals when valve cover is tight end down to torque specs!
