early 04 (03 build) F350 6.0 diesel, 150K

quit running, changed ICP and pigtail, oil and filters (rotella T), fuel filters as well

runs when its cold but quits when hot

injector oil pressure is at 560-614psi when at idle
FICM is at 48.1 volts

only code that comes up is injector pressure to low
but once warm it won't rebuild pressure to start stops in the high 4's on oil pressure

Haven't checked ipr yet, my 06 f350 6 liter died yesterday at 148K but i already figured it out with the stc plug, do you think its the same or any other ideas?

Thanks in advance

 

04 is a different oil system so not gonna be an stc fitting. they dont have them. best thing to do is an air test.

 

sorry to sound stupid but define air test?

 

steps 10e and f of the hardstart no start section of the pc/ed.
basicly injecting 100-200 psi of air in to the high pressure oil system and commanding the ipr closed.
