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).
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.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?
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.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.
