Never knew that about the fuel bowl. I'm going to put a new filter in.

Yes, the chip has been totally removed from PCM.

You can just cut the tip off the stand pipe and gut it also. That way it keeps crap from bottom of bowl out of it. That is what i do to the trucks i work on.

Put in a new Motorcraft fuel filter and new Ford fuel bowl cap....still no start.

High pressure oil in the heads was in 2500-300 range on a manual gauge. Have fuel pressure. But this time, no white smoke out the tailpipe.

IMHO: something is telling the injectors not to actuate. Even though it pass a buzz test, could the IDM be no good?

IPR wiring harness? I know you already mentioned the ICP connector, but it was my IPR harness that caused my no start.

I'll closely examine it but I wouldn't be getting any HPO if the IPR was not functional.

If youve got 25-3000 psi hpo while cranking, your ipr definitely isn't working, lol.
Unless I misread.
If the injectors aren't firing at that pressure, than it has to be a control issue, which could be the ism. Might check continuity (resistance) from the firewall through the 42 pin connector.

Are the injectors clacking while cracking?

After I keep cranking, the pressure goes up. Correct me if I'm wrong...applying voltage to the IPR closes it, raising pressure.

Can't hear them while inside cranking.

Um.. you can leave key on and jump starter relay and have your head right over the engine...

I can even hear them if I stick my head out the window and crank from cab....

I thought the pcm would limit hpo based on throttle position?
Either way, you have plenty of oil pressure to fire the injector, lol.
I was referring to the idm circuits when I mentioned checking wiring. Sorry for the confusion.
You mentioned a passing buzz test, so, for some reason, maybe the pcm isn't actually commanding the injectors to fire when you are trying to start.
I would think the idm is working if the injectors buzz correctly.
