Not sure what you mean. I did post the code on the first page of this thread.
So far I have unplugged the ICP to see if that would do it. Really trying to understand the issue without having to hopefully tear the whole engine apart.
I really do appreciate the help so far.

Benny didn't see the code post more than likely.
Go with m-chan's advice. He knows his stuff. He's a well respected Ford tech. As he said, unfortunately, but it sounds like it's time to dig in.
As has been pointed out, twice now, you need a way to check HPO pressure. If you don't have a way, then you need to pull the HPOP cover off.
A Scangauge II for ~ $160 will do the trick.
The advice is solid. It's time to move on and get 'er done.

I would take M-chain advice
cuz it going to be hard to pressure test an 03 with air plus it should be tested with air while hot

The ICP and IPR duty cycle readings can be used to confirm that you have a HP oil issue. When it is confirmed, at that point it is time to "dig in".
That being said, m-chan68 certainly has the knowledge and experience to tell you that (based on your symptoms and code) it is warranted to begin the process of removing the cover - so I would listen to him.

I'll try a little research on the subject.

Once you get the Scangauge, if you decide to go that route, then it will need to be setup to monitor the pressure and IPR valve readings. An easy task.
This is a video of an 2006, but the HPOP cover is in the same location on your truck.

To access and remove the high pressure oil pump and cover on a 2003 engine requires intake manifold and EGR cooler removal, due to the rear crossover on the intake that is exclusive to 2003 model years.

The minimum pressure to start is 500 psig.
Also, I usually think of "cranking" as the engine just turning over (no fire or start) - just through the starter (which your engine can do w/ zero HPO pressure).

That means more work for the OP, but the video at least shows you where it is.

Cranking is a poor choice of words now that you mention it...

Between Mark and cheezit, I definitely do stand corrected. Appreciate the correction. Tomorrow I plan to start my truck while cranking it to get my HPO pressure above 500 PSI, and then head off to church in my shiny truck.
