No start
Hey guys i am looking for some help. I have a 2003 F-250 with the 6.0. Will not start, worked on these engines for years but this one has me stumped. Truck was running fine. Got in it one morning and would not start, and it has no codes. below is what i have checked and done:
Changed fuel filters
added fuel
checked oil level
replaced batteries
Replaced IPR pigtail
Changed IPR
Electric fuel pump has 49 psi up top
no air inlet restrictions
Scan tool shows the following
no codes, passes inj buzz test
FICM is 48 volts
RPM 177
ICP pressure shows 1500 plus
pulse width 2.2
FICM sync yes
IPR 15 goes to 48
Oil Pressure gauge goes up while cranking
Shows crank and cam signal
engine turns over great, have tried wiggling crank sensor and cam sensor harness, pulled IPR and checked screen, checked IPR with OHM meter it shows 6 ohms, tried another IPR, unplugged ICP. Engine had new Ford HPOP installed less than 10,000 miles ago, FICM has been replaced, and all the other goodies done to it. Please any suggestions would be welcomed at this point.

Yes i installed motor craft filters. I checked the pressure before and after filter change. Pressure stayed the same, i did pull the cap off before changing filters and didn't see any signs of air. On a side not a couple days after filter change a doing some other tests the truck did start and ran about an hour. i shut it off and it hasn't started back since.
