I was driving home tonight and stopped at stop sign. I took off and truck died and coasted to a stop. I tried to start but all it does is theft light blinks really fast and will not turn motor over. I tried to reset pat by following procedure I found on internet. Still no start. I then unhooked battery cables and left off for 15 minutes then hooked up but still no start and blinking theft light. I also tried spare key and still no start. What else can I do. I had it towed to place that just bulletproof my truck. Truck has been running great. I did not want to leave it on the side off road in the middle of country all night.

 

It's a 2005 excursion 6.0 powerstroke.

 

It was the fan clutch wire. Some how the wiring got cut in half.

 

Glad ya got it . With just a couple of exceptions the F series SuperDuty didn't get PATS. Might explain the lack of responses.
