I just replaced the CPS in my wife's 1989 after doing Search and Research here.
Now it starts up and runs for a short time (under 5 minutes) and just shuts off.
Somewhere in my search I found a a reference to "Chrysler service bulletin 18-51-88" (Google it to find the PDF). The Cherokee has the upgrade already installed.
The bulletin says, in part;
Is this a different CPS sensor than the one I just bought at NAPA or am I having some other problems?
After the replacement I cleaned all the under hood connectors, battery conections and ground wires.
Thanks!

The symptoms described above could be caused by a weak signal from the CKP sensor. A new CKP sensor and harness is available to correct this problem. The new CKP sensor is available in a kit, part number 83100066. The kit includes the new CKP sensor, and a sensor patch harness for connecting the new sensor directly to the engine control module (ECM).

7. Locate the old CKP sensor on the bellhousing. Remove the CKP sensor lead from the retaining clip. Remove the CKP sensor retaining bolts, and discard the CKP sensor.
