2003 F350 Dually Crank/No Start
okay my brother just got a 2003 F350 6.0 Dually 2wd that didn't run and got it dirt cheap. the previous owner had parked it because he didn't know what to do or how to work on the truck. he said when cold it would puff black smoke and run rough and when it warmed up would run fine, and then it wouldn't start up anymore. which i could see as 1 of 3 reasons, FICM, Injectors, or HPOP.
doing tests, i found that the FICM was showing only 20volts so i had it sent out to Ed at FICMRepair and its all good now shows 48volts with key on, and during cranking.
still can't get the truck to fire over, cranking it the truck sounds like it wants to kick and start up but nothing. on the cluster of the truck it shows oil pressure on the dummy gauge. i also put in a new 5 gallons of diesel and took the fuel filters out and replaced them thinking it might be gelled from sitting outside for weeks in this negative cold spell we had here in illinois
on my AE
ICP sensor pressure is 0 with key on engine off and cranking the truck it jumps up from 0 to around 1200-1900 and seen it spike up to 2000
IPR is 14.84 with key on engine off and goes to 56.xx cranking and at one point seen it jump up to 75.xx at one point
when i did the injector buzz test i could hear the injectors clicking and the test according to the AE was successful.
i also reached up and unplugged the ICP sensor pigtail in hopes i could get it to default and maybe start that way but no luck either. also hooked up a remote starter button and cranked it over and looked in the fuel bowl to see if i could see any air bubbles from a possible bad injector allowing combustion gas in but no bubbles in the fuel bowl while cranking
the truck is showing 2 glow plug codes for cylinders #3 and #5 but that would not cause the truck not to start.
i'm thinking injectors are toast hence causing the no start. or could it very well be a HPOP issue?
