p0683
I have a 2002 ford excursion. I know they have cali emissions. It runs fine then suddenly dies while driving. We've replaced the glow plug switch and relay. Neither one fixed the problem. we washed the motor a while back and it fried the programmer wiring. Wondering if that has anything to do with it. Any help would be great

Not sure what you mean by glowplug switch and relay. I believe excursions have the GPCM
like the Cali trucks do. Maybe the relay you are referring to is for the air intake heater, AIH but I don't know if EX's have that or not

Yeah, I'm confused too? All Excursions have GPCM (not relay) and that is what your code is. That would have nothing to do with stalling... And what is programmer wiring? I (aggressively) wash these engines all the time!!
More info would make it easier to help. Does it stall at a given time (coasting to a stop, when downshifting, etc...).

P0683 Glow Plug Control Module to PCM Communication Circuit
I believe this code refers to PCM PIN #8 (Comm from the GPCM to the PCM)

I've had this code P0683 appear twice, both times I replaced GPCM, code went away. Never had any stalling while having code.

The stalling is something else. Has it been raining and have you had your windshield recently replaced?
