jeep turns off while driving,
check the crank sensor
check the mass airflow meter
i had the same exact problem it is the positive wire goin from your battery to your starter
Check the crank position sensor...
Several things can cause this but if your jeep has 100,000 miles or more there is a good chance that it is being cause by the screw in the front plate of the computer. IF it just quits while going down the road, or if it starts running rough while at an idle then quits it could be this problem. It will also crank right back up sometimes or it may take 10 minutes or longer. To correct the problem remove the reservoir on the passenger side. The computer mounts to the firewall directly behind the reservoir. Remove the screw on outboard side directly below the left wiring harness connector. IT is about ½” long. Using a good pair of cutters cut half the length of the screw off. Reinstall the screw and snug it down (do not over tighten). Enjoy your jeep. Jcdmtw@gmail.com
Check the 02 sensors, a shorted heater will caise it to shutdown randomly/
We just had this happen with our 2002 Jeep Grand Cherokee. 2 mechanics got to the cam sensor but it kept happening. Finally got a 3rd mechanic to check it and he replaced the crank sensor and got all the codes cleared. Back on the road again!
fuel filter changed crank sensor changed distributor worked on
Maybe its the hight temperature of the air in the motor. Yuo must design some ventilations...my truck did the same thing. Until I did some modifications.
i have tried crank positioning sensor , and then relays, then i have been cleaning all the grounds and any connections associated with the ignition area that i can find
Try changing the throttle position sensor located on the throttle body. Pull throttle body off 4 bolts disconnect the 3 wires clean throttle body with throttle body spray or carb spray. Spray the other sensor clean to a shine. My jeep was doing same thing no more problems. Hope this helps let me know.
