'99 F350 not starting/ low oil pressure

My '99 died as I was pulling my fifth wheel to go camping. I was slowing down for a stoplight and it quit and wouldn't start again. Put 2 new batteries in it with no change. I had it towed to a truck shop and hooked up to a scanner for a diagnosis. ICP codes all over.....they pulled it and checked it out and said it seemed fine. They also pulled the IPR and checked it and sait it was also ok. Oil pressure check showed 150psi, I have a bad HPOP. Funny......only had it in the truck for 2 weeks! 4 hrs later, new dealership HPOP only puting out 60psi. Now they think it must be o-rings around injectors, but fuel bowl looks very clean and clear to me. The ICP and IPR have not been replaced but they looked them over & said they seemed ok. Any helpful thoughts or ideas would be great, truck had to be left about 90 miles from home so I could get home for work. BTW, forgot to mention that while replacing the batteries I also replaced the CAM sensor.

The o rings around the injectors don't have anything to do with the fuel bowl. I guess it could be o rings on the injectors but I would think the pump would still produce the psi needed to fire the injectors. You might have them check the base engine oil pressure to make sure it's keeping up with demand. 40-60 psi at cold is good. 20 psi at idle with engine up to running temp.

i'm leaning on fuel issue. Drain the fuel bowl, leave lid off, and see if it fills back up. Might need to do the Hutch Mod
