Hey. Got a 7.3 diesel that starts and runs great. When you step on the accelerator, it does nothing. Accelerator still has tension but it causes no effect when pressed. Assuming it's electrical because the dash instruments are all not working too. I've checked all the fuses that say "Instrument panel" but they're all still good. Ideas?

Good morning,

Are there any codes set? I need you to check.

A common issue is an APP or acceleration pedal sensor which is the fuel pedal assembly. When this fails, it will set a code.

I attached a wiring diagram for you to view. If you have a voltmeter, we can do some checks.
