Jeep was parked for about a month after hunting season ended, went to start it and it cranks but no start. No spark, replaced the CPS and nothing changed. It says error code p1389 manufacturer control ignition system or misfire. Has good fuel pressure, doesnt even think about sputtering, just cranks on and on. Thoughts?

That code means no voltage detected from the ASD relay. I'd start by checking the ASD fuse and swapping the relay.
Here's a picture stolen from CCKen showing the location of the fuse.

Thanks for that idea, replaced both and same result. Crank no start

MOPAR or white box part?
Have you gone over the wire harness to look for rodent damage?

Mopar, actually robbed the parts from my 98 that i know works. Do not see any rodent damage on this hotrod, so far anyhow!

i am having the same issue, replaced the ecm, tcm, crank and cam position sensors, asd and tcm relay. still same result wires look good, have fuel in rails but fire at the plugs.

P1389-NO ASD RELAY OUTPUT VOLTAGE AT PCM
When Monitored: With ignition key on, battery voltage above 10.4 volts, and engine RPM greater than 400.


Set Condition: No voltage sensed at the PCM when the ASD relay is energized.


POSSIBLE CAUSES


WIRING HARNESS INTERMITTENT PROBLEM
ASD RELAY OUTPUT CIRCUIT OPEN
FUSED B+ CIRCUIT OPEN
ASD RELAY
PCM

I just bought a Jeep with this code. Wouldn't start without starting fluid down the throttle body, then would run fine. Started checking fuses and a 15 amp fuse for an o2 sensor was blown. Replaced and she fired right up, I believe it was the top row middle fuse
