Maybe this will help. I'm not reading ICP pressures right now. ICP is disconnected causing the PCM to go into pre-programmed mode for IPR signal settings. I used the ICP readings in the beginning but switched to the manual gauge for testing purposes. I have never seen any pressure above 400psi on the ICP. I'm currently waiting on my scanner to come back from SnapOn repair facility which is another reason I switched to manual gauge.

Yes that is correct. With 12vdc applied to the IPR manually I saw 3000psi.

Now you've got me there. I know the one I pulled out has the edge filter. I just don't remember the new one had it. I know when I went to International and priced one, they don't have two models. They sell one IPR for all of the 7.3 PS and I think that it doesn't have the edge filter.

I went back to the site from where I ordered the IPR. What we ordered would have been the IPR with the edge filter which is what 94-95.5 year models call for. Besides, I know the original is the correct IPR and the symptoms and readings have remained the same.

Secured HPOP from '02 with matching reservoir. Installed it after modifying engine front cover and installed new gaskets. With oil lines terminated one with a plug and the other with 0-4000psi guage saw just a fraction over 500psi @ crank speed. Hooked it back into the heads and the ICP reads a max of 470psi. Still doesn't start or even act like it wants to, with or without the ICP plugged in. Watched the IDM enable signal with a scope. It goes from 0vdc to 12vdc momentarilly when the key is turned on. It never goes back up while cranking. Buzz tests perform successfully and again I see the signal momentarily go to 12vdc at the end of the test. Test passes normally. Went out and checked the Tach while cranking and it goes up to about 200 or so. However, when I looked at the scanner RPM's, they showed 0 and never moved. Do I have a bad CPS and don't even know it? Has anyone watched the RPM's while cranking on their scanner? Do they show up there?

Well first of all, thanks to all who have tried to help. I really appreciate your time and sharing your experience with me. One of my pet peeves though is not posting a resolution once it was found. So in the spirit of non-hypocrisy, here goes.
Got the new CPS and cranked it without the GP relay connected and watched the scanner. The numbers imediately started showing up on the scanner. Hooked in the GP relay cranked for about 5 secs and heard its first pop. Kept on the starter another 5-10 secs and bam....she roared to life.It runs like a top!! Unbelievable.
Haven't been that stoked and humiliated at the same time in quite some time. The moral of the story though is this, the Tach can still show evidence that the CPS is working even though it's not. When the key was just in the run position, the tach showed 0 rpm. When I moved the key to the start position and cranked it, the tach would rise to around 200 rpm. PCM also had no codes related to CPS unless I unplugged it. The rpm monitor on the scanner is what exposed the truth. Don't know why I didn't see that sooner. Oh well, maybe this will help someone avoid the same head scratchin i've gone through for the past month and a half.

Good deal man. Glad to see you got it running again. You also confirmed for me something that I thought was true for quite some time in that the CPS can be faulty and show rpm readings on the instrument cluster tach. I had this happen on a friends truck and we went by what we have read on the forums and replaced sensors and other really expensive parts to no avail. Then we changed the CPS as it was just about the only thing left to change and same as you she roared to life. Way to follow up on the fix by the way.
