No throttle, elec issues

[CanadianDiesel]

Well my truck got stuck tonight in some snow, trying to get out a Jeep Rubicon and an Avalanche. Anyways, that's irrelevant.

We fred up the jeep, to then help pull me out. the front end of these trucks with the 7.3 specially are heavier than hell. I just kept sinking. Final pull, she's comin out, givin her good throttle (thinking alright, I'm out!)

She just revs right down to 900RPM as if I let off the pedal.
Door lock actuators are going insane, wait to start beeping is constant, now here are the SYMPTOMS:

-IN 4WD and 4WD-LOW, I have absolutely no throttle.
-IN 2WD, I have perfect throttle, but whenever I let off, the wait to start tone is heard and door locks go nuts.
-I have no speedo, no tach, sweet f-all on the entire cluster. Radio works, lights work, signals works, brakes, everything.

Note I still have 4wd and low, and they lock and spin the tires but no throttle.

I'm pretty depressed right now, hoping for some insight, but I'm prepared for bad news.

Last item that might help: the truck was hoping/shaking during last pull, trying to grab traction jumping around.

Any help much appreciated. 1 Foot of snow coming this week and a truck with 2wd/no go in 4wd is useless to me

Thanks again, and sorry for the rant and very long post.

I remember reading somewhere about someone that had similair problem that when they would shift to 4wd electronics would go nuts. Turns out it was most likley PCM, because everything electronic runs through it. Here is the thread Matt, take a look.
2002 7.3 Dies when 4x4 is engaged or high beams are turned on .

Thanks for the link Tyler. I started pulling fuses from inside the cab, and #19 is blown. I'm making a run to get mini fuses...hopefully that solves it. If it does.....man will I be happy!

Right on dude, glad I can help. Let us know how it goes. I'm leaving the house for the day, but you can reach me by AIM KCharger9, it goes to my celly. See ya dude.

Well, replaced fuse #19, and everything is working perfectly again!

It's amazing how one fuse can collapse so many other features! I'm really glad it was just a 1$ fuse and not 10-15 hours in the shop or something like that.
Thanks for the help!

Yeah, I'm lucky it was this simple. I just checked the manual, and this is what it's for: Auxiliary Powertrain Control Module/APCM, Instrument cluster, GEM module, Overdrive Cancel switch, Idle Validation Switch.

Thats a lot of s*** for one fuse. I wonder how you blew it? That could be another thing to think about.

On a good note though, glad to hear you got it working Matt, now go blow some snow!

[CanadianDiesel]

Well, Tyler like you said I should be worried about why it blew the fuse.

It blew again today when I was in a parking lot. Lucky I still had the spare 10-amps in my truck...

Does anyone know what could be causing this? By the looks of it, I'm the only one that's had this issue
