2000 f250 7.3l, my Hpop lines blew and replaced them and icp sensor, filled the fuel bowl. Had to do the gas trick to get it to start it went about 2 miles fine then lost all power. Towed it home and took the icp sensor out to see if it would shoot oil out and it did replaced the ipr valve. Dead headed the pump it went from 500 psi to 3500. Put a scanner on it today rpms are normal so not the cps. My ipr is 14.9 which is wide open but my icp was 80 while cranking for awhile and it should be at least 500. So now thinking a busted o ring somewhere or an injector is leaking maybe the idm?
