Could be a problem with the Idle Validation Switch. If that's sticking, it won't rev. You could try some contact cleaner spray on the IVS (located on the accelerator pedal assembly).
 
I have the same problem on my 2000 f350 but mine has manual transmission. All other lights and gages still work. Replaced several fuses today. Help?
Which fuses did you replace?
Were they each blown?
Did you replace fuse #19?
I do see you have a ZF-6.
 
According to the wiring schematic RT provided in Post #2 of this thread, page 3 of the .pdf, fuse #19 can still be the culprit for your symptoms on a 2000 ZF-6.

It should be a 10-amp red fuse.

Did you replace the same fuse several times or multiple fuses and do you recall which ones? If the same fuse several times then it will be easier to track down the short.

Can you pull up RT’s wiring schematic from post #2? It displays everything that shares that circuit.
 
This is the schematic from RT post #2.

Share the circuit Fuse #19:
—Instrument Cluster.
—4 wheel drive control module.
—Accelerator Pedal Position Sensor.
—Clutch Pedal Position Switch
—APCM

Did you already follow Kevin’s suggestion?
 
Are your gauges working. The fuse that does the OD light, gauges and throttle pedal is the same - if the wire in the shifter shorts and takes out this fuse, you will have no throttle response - View attachment 22217

Apart from that, the actual throttle pedal could be bad. This is a fly by wire system, so no signal - no throttle.
Thank you RT - hit it right on the button and I did the fix yesterday (electrical tape) and though it was a booger finding the rough spot on the wire, I got it done! On my truck, I had to pull the shifter lever before I could find the short.

Thanks again :)

Hey I was changing out my transmission shifter bushing and I had to drop the steering column and I had the truck running the whole time and when I was done I went to screw the column back up and the truck shut off and I was wondering why and turned out I had pinched the wires to the throttle tried to fire it up but didn’t turn on and I unscrewed it and moved the wires then the truck finally fired back up but throttle didn’t work but turned on and idle perfectly . Cut and spliced the wires where they where pinched and still didn’t fix the throttle issue . Checked the fuses and changed the blown ones out and still didn’t fix the throttle . Messed more with the wires because thought that what the issue was and after that the truck doesn’t want to turn on and at first the check engine light would only turn in when I gave it gas but now that the truck doesn’t start the check engine light stays on . What should I do
 
I have a 2002 F250 with the 7.3 in it, and it starts fine, runs good and will go into gear and move, but there is no throttle response. its like the pedal is not hooked up.... what should i look for to remedy the problem? thank you
im having the same problem in my 1996 7.3 but in park it rev just fine. so if u found out what was wrong with ur lmk
 
Confirmed that RT and the pdf linked above are totally correct— Thanks RT!

I would recommend checking this issue no matter what before you replace your TPS sensor/ pedal assembly.
The wire on my 02 7.3 was abraded all over the place especially at the plastic hold down clip. I just taped the wire, rerouted it so it can move with rhe shifter and not snag anything—and done. Problem gone.

Wish i knew about this before I got 2 TPS replacements
 
Now that i am at the pickup, it is actually a 2000 year model.... the throttle actuator/pedal is a sealed unit. sometimes it will throttle up momentarily, but then nothing.... is tbere anyway to trouble shoot whether its the pedal or the ecm?
There was a recall on the throttle position assemblies and Ford replaced the assembly on my 02. Maybe it covers your year model?
