2001 Excursion 7.3 blowing #19 fuse, no throttle response
This is now happening to mine as well. There have been no recent modifications.
After about 5 times of starting, running it, and everything seems fine,
the next time I start it things still seem normal until I shift it into Drive and then there's no throttle response. As I recall the anti-theft red light flashes as well.
Next, upon stopping the engine and attempting to restart it, the "Wait to Start" instrument light is then gone, there is no cranking or turn over of the engine. Maybe this is when the anti-theft red light flashes (unsure).
I check fuse #19 (10 amp), and it's blown. Replacing fuse 19 solves the problem. The Service Engine Soon light illuminates and goes out after a few start-ups. NO CODES are showing.
Might anyone have an idea of which wiring harness section and its location, to go about checking for shorts?
Thanks,
Matt

Happened to me today
What a great site for quick, and much needed, information!
Drove to work site today, everything ran perfect. Left running while I checked out a work location and when I shifted her back into gear all the gauges just went dead. The throttle also did not respond but I was able to idle all the way back to the office. After checking the FTE forum page and reading this information, I went out and checked all the fuses. Sure enough I found a blown 10 amp mini fuse. Replaced the fuse, restarted and everything working perfect again. Have driven it a couple times and so far the fuse has not blown again.....I hope this does not happen again but I bought some extra fuses just in case.
This fuse was in a different position than what was stated earlier. Mine was located in slot #45 in the very bottom horizontal row of fuses, 4th one from the right side. Thanks everyone....

The FIX for mine was opening up the steering column and finding a hidden short from the wires rubbing against the metal steering column brackets. The wires are tied to the shifting lever (on the right of the steering wheel), and the short was hidden. Had to disconnect the shifting lever harness, install electrical tape padding on the metal bracket, treat the wires so as to seal them up again, and wrap them. No problems since, and it's been 20,000 miles. The harness was routed too tightly, and so every time I would shift into 1st or 2nd, the wires were pulled into direct contact with the metal bracket, which popped the fuse.

Well......I spoke too soon! The damn thing blew the fuse again today and stranded one of my drivers in the middle of an intersection, so you can see why I'm a little bummed out. Now, however, the fuse blows every time I replace it! Anybody have any ideas? I think the GEM module, overdrive cancel switch, instrument cluster idle validation switch and Auxiliary powertrain control module are on the same circuit. Guess I'll just start trying to isolate them. Thanks for any help...

The harness was routed too tightly, and so every time I would shift into 1st or 2nd, the wires were pulled into direct contact with the metal bracket, which popped the fuse.
I disassembled the column shift lever, retrieved, repaired, and rerouted the wires, reinstalled the shift lever, started up the truck, ran through the gears to test, it all worked, and then boom.. problem again.
My rerouting of the wires to prevent the same chafing from repeating... ended up not taking into consideration the full travel of the shifter in all positions (It stopped working when I shifted to Manual 1).
This "short" sightedness cost me $80 for an entire new shift lever, as I now had an OPEN inside the lever arm (wire ripped apart), and the design is such that the wires cannot be retrieved and rethreaded through the lever arm within the number of hours, paid at half of minimum wage, that it would take to buy an entire new arm, which is the only way that Ford services and supplies this harness made up of three wires that are about the gauge thickness of a human hair.
Lesson learned... be cautious in creative attempts to prevent an obvious problem... the consequence can be the creation of a new, not quite so obvious problem.
There also could have been another force at play...
