Ok. So I bought this Cherokee running. It's got a 1991 motor in a 1999 body. The swap was done well. Haven't had any problems until this happened. I took the doors off and cut the wires (probably shouldn't have done this but it's a play toy so screw it). The battery died the next day so i jumped it off. I took the cables off the battery and The engine died. Replaced the alternator and the battery. Now it is not getting spark. It's got fuel pressure at the rail.

Things I have changed:
the ecu(spare one I had laying around), coil pack, distributor, crankshaft position sensor, and the camshaft position sensor.

Need help. Trying to ride this weekend!!!

Did you check the under hood fuses? Especially the ecu. Had a 96xj where the ecu kept popping the fuse. Swapped in a good used one and solved the issue.

Just a random guess.

Thanks bro! I figured it out. When checking the relays. I accidentally pushed one of the wires out of the bottom of the relay box.....
