I have a 92 Dodge D-150 with 76,000 miles on it. It has, on 4 occasions just quit running, always seeming to be brought on by hitting a bump in the road. The first time, I coasted to a stop and tried starting it. No go. Turned off the key, then back on, fired right up. Second and third occasion, pretty much the same except it seemed progressingly harder to start. The last time it happened, it wouldn't start at all. For lack of nothing better to do, I turned off the cruise control switch, started right up. I checked the wiring diagrams but found no shared components between the cruise control system and either fuel or ignition systems. I changed the Auto shutdown and fuel pump relays, but no help. I now shut the cruise control off when not in use, instead of kicking it off with the brake, and have had no more trouble. Head Scratcher. ?
It is a head scratcher. I have a 96 t& c and recently mine has started doing the same thing and the only thing I can come up with is that a sensor has gone out somewhere. Now don't hold me to that answer, couse this is new to me to. But I have had more trouble with this vehicle than what it's worth. Sensors gone out had replaced and the samething is happening again. But the stalling hitting a bump thats new.
