Why Does My 1989 Jeep Cherokee Die At REGULAR Running Temp And Not Start Again Until It Cools Off.
Posted in Ignition Systems | Asked on Aug 8, 2010
I’ve replaced the crank shaft sensor as well as the ignition coil. But it still dies at regular running temperature. and it wont start again until it cools off.
To all of you out there that think this is the thermostat, it’s not. A thermostat in a 1989 Jeep Cherokee will not cause it to die.

It sounds like the iginition module. You are having classic symptoms.
need more info – do you have a check engine light on? if you do take it to a shop & have them tell you whats wrong – in the long run you’ll save money….
we have a jeep in here right now that stalls out in second gear only, in all other gears it runs normal, with a little lack of power. we found the catz broken internal. — that would have been very hard to find without the computer to point us in the right direction.
Two off the top of my head ideas…..
1. Fuel pump ballast resistor. Its a white porcelin resistor on the fender by the air box.
2. MAP sensor Its mounted high on the firewall almost over top of the motor.
The Cherokee does not use an ignition module that can be affected like this. Both Cherokee motors in 1989 used an ignition module that is underneath the coil mount. No it can’t be a thermostat either. Its not hooked to anything, and the coolant temperature sensor is in the other end of the motor and doesn’t affect the system in this manner.
sounds like a controller problem, they overheat and will not kick back in until they cool off
