First time poster- I appreciate ANY help! Thanks in advance.I have an 02 F250 7.3. My wife called said the truck wont accelerate, just idles, and no gauges. I've had the fuse blow (#45 I believe) twice before. I drove an hour away to replace the fuse. Turns out there were NO blown fuses unbelievably. I checked and rechecked all of the under dash ones. After reading the posts here I was sure it was the OD wire in the shifter being chaffed. So I removed the steering column cover and checked. I didnt see anything, started the truck to see if I could get the gauges back while wiggling the wires with no luck. Turned the truck off, tried to restart the truck, and found the truck will now NOT START either! Anyone have any ideas?? Please help if you have any ideas. Thanks to all

 

First off welcome second did you check all the fuses in the under the hood fuse box also.

 

Thanks pipe... I've got great advice here on one or two things before, Checking the overdrive wire is one of the with great pics showing the procedure. I didnt check anything underhood as I'm unfamiliar with the underhood ones. I was so optimististic I would find a chaffed OD wire and fix it, but was confused on the symtoms without a blown fuse under dash. now truck wont start plus the original symptoms

 

On the drivers side fender well there is a black box you have to pop off the cover and there is lots of fuses in there also along with some relays.

 

In your owners manual it will say underhood fuses showing that panal and what those fuses and relays are for.

 

The 2002 7.3 doesn't have the fuse box underhood. Only 4 relays are underhood.

I had a very similar symptom with my truck. Pretty much exactly as you describe. It was a fuse. I can't remember off the top of my head which fuse it was...let me do some digging.

EDIT:

I found that for me it was fuse 23. It was not blown either, but not making good contact in the fuse box. You might go back to fuse 45 and pull it out and twist it a little bit and re-seat it. I would check fuses with a multimeter to make sure everthing is right.

Fuse 45: Clutch pedal position switch, Auxillary Power Control Module (APCM), Accelerator pedal position sensor, Overdrive cancel switch, 4 wheel drive control module, Instrument cluster.

Sounds exactly like what you are experiencing.

Any chance the battery may have drained on the truck?

 

Those are the Exact symptoms I have. The thing that threw me off was no blown fuse this time. I think I'm to blame becuase the last time it blew the fuse I put the only one I had in, a 25 amp fuse. So I probably melted down something before the fuse. I had to drop it off at a Ford mechanics house. He called and said he by-passed something and got the gauges working but still had the 4x4 light on. I believe he probably by-passed the power control module? Now he's working on the 4x4 light. I believe I probably could have fixed it with all the help from this site. I'll let you know what it turns out to be when I get it back. Thanks for the suggestions.

 

Same problem , no gauges and some time no start, i have to play with the shifter or put it in neutral!
My batteries did drain dead! No blown fuses! I checked under the hood as well!
Mine is a 2000 F-250

 

I had a cam sensor go out and my 7.3 quit running also 90 bucks to repair.
