Well I finally finished up taking all the car alarm/remote start out of the jeep. that solved the doors locking and un locking themselves ever few seconds, but now it will crank but not start.....sigh back to trying to locate the new issue! Sorry it took so long to update but the weather has not been very conducive to working outdoors in the driveway!
If you have removed the car alarm system you have possibly killed the SKIS anti-theft operation!
You should have a red LED on the LHS of the cluster which is the SKIS LED.
This should light up when ignition is first turned ON then should go out within a few seconds if the ECM is happy with the chipped code that the SKIM module on the top of the steering column reads and sends up to the ECM.
If the LED light does not go out but flashes then the ECM is not happy with the chipped code sent from the SKIM module....engine will fire up but will cut out after a few seconds.
If the LED is ON all the time then the ECM is happy with the code it received from the SKIM module but is not happy that the ASD relay has not reported back to the ECM that it...the ASD relay....has energized. The motor will turn over but not fire.
So first check if this LED stays ON or flashes at you....if it stays ON then try swapping over the ASD relay with an identical one.
I had this problem with the Jeep turning over but not firing and the SKIM icon....older KJs use an amber "key" icon....staying ON.
This I overcame by removing the ASD relay and jumping the empty socket female pin 30 to pin 87....Jeep would then start and run until I managed to trace a broken wire going to the ASD relay coil to fix the problem!
