Asked by GuruZ9S6R Dec 29, 2019 at 07:15 PM about the 2006 Ford F-550 Super Duty Crew Cab 176 in DRW

Question type: Maintenance & Repair

Had mechanic come hook up box to it and said low pressure fuel. replaced with
new fuel pump and still wont crank. Was told to replace Diesel high pressure oil
pump. Cant keep guessing and replacing. Any suggestions? Had been running
fine and it set up for approx. 3 weeks and went out and started right up and
idled for 10min. then shut off.

If the lift pump is weak you won't get enough fuel pressure and if the high pressure pump is shot you also will not get enough fuel pressure. It takes both. The 6.0 is a money pit.
