Question about 2004 Ford Super Duty F 550
Do you know the reason for the damaged injectors? 1. VERIFY the Inertia Fuel Shutoff (IFS) switch is set (button pushed in). REFER to the Owner Guide for location 2. Check fuel pump pressure, Pressure Specification (KOEO) 5.4L & 6.8L 35-45 psi (240-310 kPa). If you don't have a Fuel Pressure Tester, you can borrow one form an Auto Parts Store like AutoZone, Checkers and others.
Have you messed with the plugs?? It seems that on your type of engine the plugs are very hard to remove and there is an special procedure for that, and if not followed, the plug may break. here is a flow chart on plug removal for your vehicle.
THERE ARE TWO PCM POWER RELAYS AND FOUR FUSES, CHECK THEIR FUNCTIONALITY
GOOD LUCK!! KEEP ME POSTED
