2005 6.0 (late 04 production date). First it had fuel tank delam/rust issues. Replaced fuel tank and fuel filters. Crank but won’t start, removed IPR valve, and the screen was clean. Had an extra new IPR valve laying around so I installed it. Still won’t start, I’m getting no ICP pressure and .25 volts. Oil level good, low oil pressure shows on dash gauge (halfway while cranking). FICM at 48 volts and synching. Do I have a high pressure fuel pump issue?
also worth mentioning, I did all injectors, EGR cooler, oil cooler, and turbo replacement. Truck ran good for a few months other than having to replace the fuel filters about every 500 miles. It’s a company truck, I told the boss that it needed a fuel tank but the company didn’t want to spend the money so they told me to just stock up on fuel filters instead. I’m afraid something went very wrong and all that works I did was in vain. Don’t know where to go from here.
