No "wait to start light" and more.

[casacoboy]

97 F350 PSD, 1 owner, 170,000 miles, no previous engine problems. While driving the engine quit, no warning - just like I had turned the key off. It turns over but no "wait to start light". I have not found any bad fuses, I did change the crankshaft position sensor. The APC module (sets a fast idle for warmup) displays "C ERR" after self test.
Any ideas.
Thank you

you said no bad fuses, but did you check the ones under the hood in the power distribution block, possibly #22

I think I heard Marc say PCM if the WTS light doesn't come on...

But I could be totally off base. Doesn't help much, I know. Sorry.

Bump!

Sounds like the PCM to me too since all the fuses are good. the other thing to check is the fuel bowl heater and fuse for that

Found it in the other thread:

the #22 fuse is the one for the fuel bowl heater,been there done that, and that was it, also same symptoms, was running then just quit and no wts light, engine would spin over but that was all

Okay, the #22 fuse was blown. The underlying problem was a bad glow plug solenoid. Only bought 1 part I did not need, the CPS, but now I have a spare! I also realized that had I disconnected the lead to the fuel bowl heater and glow plug solenoid (and replaced the fuse of course)when the problem happened I could have been back running in minutes and figured out the real problem later. Not a problem this time (I was 1/2 mile from home), but I pull a 24 foot gooseneck full of cows quite often and it would not have been a good thing to have happen then.
The forum is great .
Thanks for the help, I am now a wiser man.

Sweet! Sounds like you came off relatively unscathed!
