Should I replace The Hpop?

[ArNy64]

Hello i have a 2003.25 f350 6.0 i bought it 3 months ago now it wont start.The whole story i had with it is i changed the oil using 15-40w and oil filter and cap all new motorcraft parts.Drove fine for 3 weeks no problem.Then i drove the truck maybe 4 miles turned it off then turned it back on, for maybe 10 seconds the engine was idling the oil pressure dummy gauge wasnt reading anything, then i pressed the accelerator a little pressure went up to normal on the gauge the truck stuttered then died. Then had it towed home. I unplugged the icp sensor to see if it would default and start but no luck. So my scan tool read the ICP sensor was .24v and 44 PSI with KOEO.The ipr also calculated 14 something percent. When I cranked the engine ICP Stayed at 44 psi and .24v. The Ipr went up to 80%. I Also saw the fuel pulse width was at 0 when cranking as well.All FICM Powers Were Normal 48v. So doing some research online alot of people were saying its the hpop i tore the motor apart got the hpop out today. So i ohms tested the ipr and it would jump around and stop at .06ohm so im guessing the ipr is bad as well.Which doesnt make sense cause it seems to be calculating the percentage correctly when i look at it on my scan tool.I just wanna see what guys have to say about my problem and what i can do to test my hpop and anything else, I've been reading about people having the similar problem im having and replacing there hpop and icp and ipr with still a no start.I just dont wanna throw out that much dough that quick for a pump.
-thanks
