Question about 1988 Jeep Cherokee
I kind of agree it may be the ecu. but first, look for a green 20amp fusible link, turning into a red wire. Your wiring diagram shows this fusible link is the power source for the fuel pump relay. It is called Fuse Link G. Should be near the battery.

I agree. you probably shorted a circuit in the ecu. pick up a cheap one from a junker and plug it in. at least you will eliminate that if its not the ecu but i bet it is.

check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

Check the crank position sensor. I had the same problem in a 1989 cherokee 4.0, and the solution was simply to acomodate the sensor wiring. No replace was necesary

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered
