just got a call from a friend who was driving and his truck died going down the road like the key was shut off. just a total loss of power. at first i thought maybe a cps but he just called back and the wts light doesnt even come on before cranking. is this do to a pcm or are they even related.

 

No WTS light and the symptoms point to a CPS. Ask him if the tach moves when cranking. Also, make sure to get a dealer or Motorcraft CPS, NOT a parts store replacement.

 

10-4 for on dealer parts. i forgot about the tach, and didnt realize the wts light was related thanks and we will get a cps put in

 

Also check fuse 22.

X2 on what Jarrett said. I would also check fuse 22.

what all does #22 feed power to?

 

X2 ^^^ check fuse 22. If blown unplug the fuel filter canister heater wire, put another fuse in 22 (30A I believe), common problem.

 

#22 feeds power to the PCM.

Lots of things but most importantly the PCM and fuel filter canister heater. If the heater wire shorts inside the fuel bowl it blows fuse #22 and kills power to the PCM, thus no WTS light. IIRC it the second from top connector on drivers side on fuel bowl. Hard to remove because it's a spade type push on connector.

 

Yup, what these guys said

 

Thanks so much. Haven't dealt with that in quite a while it is almost a crutch to know I can turn here for help
