need advise on a no start

FORDPWR · Jul 29, 2016

Alright, I hate asking for help on a 6.0 no start since there are so many out there with this issue but I can't seem to solve my problem. Coming home one night, took off hard and let off around 60mph, went to hit the peddle again and there was nothing, soon after truck just died and rolled to the stop sign. Had my dad tow me home, hooked the x4 up, icp was only reading 390 psi and IPR was at 85%. 4 years ago I did all the bulletproofing, from head studs to a new hpop. So a few days after I tore it down this king something let loose. I did an air test and everything seemed to check out. However after leaving150 psi of air hooked up to the icp Port for 5 min I could hear air. There were little bubbles coming from the back of the pump. Then I pulled the pump cover and dropped some oil into the pump, did another air test and there was no leak. So I hooked my gauge up to the icp Port, cranked the truck over with the little wire on the passenger side fender and my gauge would not move. So I closed the IPR valve and cranked it over again and the gauge went to 2500 psi. I'm really stumped on what my problem is and any help would be great._I forgot to add the day after it dieing, the day after it died I checked for oil pressure again and the x4 read 500 psi with IPR 85% closed, but still would not start. First time this truck has kicked my but, any info would be great.
