Help! Truck starts, but no pedal and gauges do not work
My son's truck is a 2000 f-350 7.3 dually. Truck starts fine but no throttle response and no gauges. Only idiot lights that come on are airbag and seatbelt, no glowplug indicator. Truck worked fine before. All fuses are good. Tried a relay to pcm swapped it with blower motor relay and no change. Have looked through diagrams trying to narrow this down.
The shifter arm is a little loose (240,000 miles on truck) and the OD plastic tip end broke , but still worked and was taped to shifter. Read on another post that this could be a problem, but button always worked....WHere does the shifter arm come into wiring diagram to cause this or any other ideas?
I have a programmer that can pull codes( From my truck, the 2000 is stock program..my truck is '03 7.3) ...
the codes it pulls after being cleared and restarted (same codes)
P0381- glow plug indicator circuit malfunction
P0221 throttle switch b circuit performance
P0470 exhaust back pressure sensor circuit malf.
P1139 water in fuel indicator circuit malf.
Could this be in ignition switch? Shifter or sensor in column for sensor..pcm..????
All help appreciated....thx....
