01' 7.3 Died

[Ronney]

This one has me baffled.

I'll try to make this short but include as much detail as I can, considering the situation.

Driving home after getting the groceries the truck (01’ F-250, 7.3L) dies. I pull off and eventually get it started and it only makes it 200 feet then dies again.

I checked all fuses, wiggled all the wires and checked vacuum lines; she would not crank. I did get an intermittent check engine light. The only time it would start was after I turned it completely off and let it set for about 2 to 5 minutes. Once I placed it in drive it would die or if I pressed on the throttle.

I finally ended up wiggling the pedal wire bundle, (don't know the technical name right now) anyway, it started again and stayed running in idle for quite a while. When throttle was applied it started to die then I increased throttle even slower it seemed to work fine. I dropped it into drive and it died. I got it cranked up again and repeated the process again it died when I went to drive.

I shut it down then turned the key on and started wiggling the pedal wires again and the tachometer started jumping up to 1K. Additionally, there were electrical shorting type sounds as if it were not quite connecting?? I stopped at this point.

Good news is I got my groceries home bad news is I'm stumped.

My plan of action is to have it towed to the nearest dealer and have them throw the computer on it and see what comes up. From what I've read it could be a number of things however, when dealing with spark chasing the experts need to be called in... ANY HELP IS APPRECIATED: confused:

when you went to crank it over, did the tach move?? if not, your CPS is probably going out. there is a recall on this part at Ford.

Mine did the same thing it was the CPS. I found several on EBAY for a lot less then the dealer.

Get a CPS....

Sounds like the CPS to me also mine shutoff at a light cranked back up and did it again the next day got a new Cam Position Sensor and has been fine ever since.

Mine was doing the same and the recall on the CPS fixed it good as new.

[Ronney]

Thanks

I have it at the dealer right now ($$$ ouch!) I have them running a diagnostic on it as well, since the Tach was jumping all over the place the sounds of it shorting out with just the key on without being cranked up. Dealer thinks the same thing...CPS

I started up the next day and it drove about 50 miles to the dealer just fine.

I appreciate the help folks.

There is a recall out right now for all 7.3 cps sensors,don't let them charge you if that is the issue.
