Vehicle Quits While Driving
Engine Goes Dead While driving Q: Jeep Cherokee runs well 99.9% of the time. However, sometimes when driving, it will go dead. Usually it cranks right up when I pull to the shoulder of the road. Sometimes it will run for days with no problems. Other times it goes dead two or three times a day. I had it in the shop for a week, but they could not find anything wrong with it. Any suggestions? A: If your Jeep is shutting off like someone turned the key I would be critical of the crankshaft position sensor. While your Jeep is running you can unplug just about every computer sensor on the engine and it will still run, not great but run. If the signal from the crankshaft position sensor is lost on your Jeep, the curtain drops like a rock on that show. The fuel injectors, along with the ignition system, are shut right down. Just bang, end of show! While the crankshaft position sensor is off line from the rest of the vehicle, you can crank the engine over until the battery goes dead...
