7.3L Power Stroke Engine and DrivetrainDiscussion of the 7.3L Power Stroke diesel engine and drivetrain in the 1999-Up Super Duty trucks and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
Where to start. I have a '03, 7.3, CC, SB, 4x4, with 4" exhaust, AFE stage2 intake, Edge w/attitude.
I drove the truck approx. 120 miles yesterday with no problems and leading up to this in the past 6years no problems of this sort.
The short and sweet of my problem is that after the truck sat for about 5 hours after the 120 miles, I had hooked up to my 10,000lbs trailer to move it to the other side of my street 150 ft total trip, which went fine including turning around on a hill untill I pulled into my yard to strighten out. I put the truck in reverse, you could hear the trans go from drive to reverse but when I hit the accelartor, nothing. You could put it to the floor. Went back to drive, still nothing with the accelartor. The truck moved but only at idle speed. I also notice on my instument panel my odometer was out, and fuel, tac, trans temp.... the whole cluster to include the head lights only on auto would not work. Everything else electrical and mechanical is working. checked fuses I thought would be related to this problem (williing to check again) and none blown. Fluids seem fine (on a slope) HELP!
Just when out this morning hoping it was just a gremlin, not. Still same deal and I have a job to do. figures! I guess that wasn't very short, hey?!
Well, our accelerators are electronicly controlled. So the assembly could have failed, fairly common. HOWEVER I have not heard of anyone loosing other gagues and such on the instrument cluster from that. SO I WOULD really figure it's a fuse or wireing problem. Maybe mess with the wires behind the fuse panel? (I had a problem with the wires on the starter relay there recently,, just a thought and easy to check out.)

I'll give it a shot. Thanks. Ii also tore apart the column and check the wires and disconnected the edge system. found one blown fuse for the trailer charging system.
I just had the same EXACT thing happen to me 2 weeks ago. I drove it to where I was going. No problems. Went to start it back up and just like your problem. Shell start and idle. But no gas or guages. Autolight did not work, either. My shifter wire for the OD button was broke. Fixed that still same problem. Took it to Ford, I could not find the broken wires. Turnes out I had three other wires broken somewhere down the column. And according to ford a broken connector. You got me on the connector. But thats what they said, its been fine since they fixed it. I really needed a wiring digram.
Had the same thing happen on my 2000 F350, the OD switch in the column was a shorting out, blowing a 5 amp fuse. Replaced the shifter lever, all was good.
Same with me. I bought a new shifter and all is good.

Not completely off topic and maybe a dumb question but could that be an issue with a manual transmission?
Not a dumb question at all.
The manual doesn't have that wiring in the column, so it wouldn't get broken and take out the instrument panel/IVS fuse.
That doesn't mean that the fuse blew for some other reason however. It's also possible that the IVS (Idle Validation Switch) went bad. It's there to prevent the engine from revving up unless someone has actually pushed on the go-pedal. If it fails, the PCM only lets the engine idle.
Some of you are replacing the column shifter and others are replacing the throttle assembly...
Help...I'm having the exact same problem with no throttle response (I did not notice the gauges working or not). The problem is getting worse but if I'm patient I can usually get it working again until the next stop light (and now it's so bad it's happening at most stop lights). The fact that I can get it working again tells me that my problem is NOT a fuse (but please tell me if my logic is flawed). What fuse should I be checking anyway? Nothing in my manual is labeled Idle Validation Switch. I'm going to go out and pull the column cover to inspect the wires but please someone feel free to chime in...is the problem wires in the column (column shifter assembly) or the throttle assembly? If there is not an obvious broken wire in the column how would I diagnose?

Reason: update
Okay...so I pulled the column shifter lever...disconnected the 3-wire connector and inspected the wires. There is no 'obvious' break or wear mark on the insulation. No way for me to be positive but the wires 'appear' to be okay.
HELP

If you find that it is the overdrive wire loom, insulate the shorted wire, tape it up, and replace #45 fuse. Thats what fixed the broblem for me 2 weeks ago on my 2002. Exact same symptoms.

Check-Engine light is on but the ODB 2 reader I own will not pull codes off my truck (works fine on my jeep but not the truck - must not be compatible)
I'm going to 'try' to borrow a code reader but other than that I'm still open for suggestions.
