Question about 1994 Jeep Grand Cherokee
My jeep dies as I am traveling dwn the road with no warning. It happens every time I drive it. Then after a few minutes, its starts up again. I have disarmed the security system which helped, but it still dies, any suggestions? PCM maybe?
This is 100% certainly the "CKP" or crank possition sesor. I had the same problem on my SE 4.0L cherokee, i replaced the ignition pack - leads, dizzy cap, coil as the dizzy cap had major dirt and arc marks inside, king pin lead was loosing connection when warm also.
However this did not solve my problem, it helped, thats it.
I then used the in car diognostic system to see what that told me, sure enough - code 11, code 12 and code 55. meanings as follows.
11- no signal from crankshaft sensor
12 - main battery power disconnected
55- end of test
Once i replaced the crank shaft sensor and disconnected the battery for 30 mins to reset all fault codes it removed code 11.

Hope this helps people out there!

I had this problem myself. It turned out to be the crank sensor. It bolts into the bell housing.

I did read this problem with the car shutts down if you will pull your feet out from the gas pedal, or pushing the brakes, i had 5-6 diffrent Grand Cherokee, from 94-98 all the same problems, and after changing the battery of the car, everything went fine, i used to be a car dealer, and when the crs were not running, the battery drains a little, even i could start the car from the first time.
So, i suggest that you change your battery to known good one.
Hope this Helps.

I have a 1994 Grand Cherokee, and I can tell you first had that the first place to start when jeep just start to turn off is the CPS, or Crank Position Sensor. it is mounted on the driver side top of bell housing, just at firewall. I have gotten to the point I can change it in 15 min on the side of the road, and I always carry a spare. it's held in place with one 10mm bolt, and the wire lead wraps around off to the Distributor harness plug area.

I have read that this problem of stalling, or engine dying while in motion, is due to a bad cam position sensor. Replacing this sensor should solve the problem.
I don't know much about this, but I am researching problems with '94 Grand Cherokees prior to possible purchase of a used one and found this to be an oft-cited issue. The aforementioned solution was suggested by several sources. I have no verification of the utility of this advice.

Hi when it doesn,t start up you need to see if there is a spark at the plugs or if it is fuel as there are quite a few possibilties and guessing can be expensive if you find out just get back and lets see if we can sort it out for you yates210456
