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

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 -

Apart from that, the actual throttle pedal could be bad. This is a fly by wire system, so no signal - no throttle.

Sure - put a scanner on it and watch the TPS signal. Do you have functional gauges? Do you have an OD light? If it is intermittent is is most likely the TPS (pedal assembly) - the PCM going out would be much more unusual.
I had a no throttle response on mine and put 4 or 5 different assemblies(same part no.) in and continued to have intermittent issues for months until I tried a different part # that NAPA had. No problems since. Both part# were ford reboxes and the assembly that worked looked completely different but it fit. I'll see if I can get a part#.
Isn't there a recall out on the pedal now?

My 2003 7.3l once lost all throttle response on me. Ran fine just nothing from the go pedal. I found a blown fuse and replaced it. My Excursion fired up and I had throttle. I dropped into drive and lost throttle. I did this about 3 times. Had it towed to the stealership and it was the Overdrive override button wiring. It had shorted out. When I would drop it in hear it would blow the fuse. It was a simple fix. But expensive diagnosis. Good luck.
A momentary short in the OD switch wire on the gear selector stalk will do that.

It applies to your truck. If you read through, it lists fuse numbers for the 99-01 models as well as the 02-03 model. The circuit is the same. For a temporary fix, pull the steering cover, unplug the OD wire and replace the fuse. Then, you can drive the truck while you are waiting for the new shifter to arrive.

My 2001 did this, blew the #19 fuse, repeatedly. Worn wire from the O/D switch shorted to ground. Took it apart, taped the wire, re-routed it a bit, a little slack in the clip, and back up running perfectly. Thanks in no small part to this thread and the internet search that found it. Thank you, thank you, THANK YOU!
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.

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).
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.

Got it fixed. Found a wire that was rubbing on the clutch pedal up under the dash. Every time I pushed the clutch the fuse would blow. It was easy figuring it out from that.
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
