Has anyone had this problem where the tj will crank and no start there’s fuel but now spark. There are no codes. Checked voltage and grounds to the ECM there ok the one thing that not there is the negative for the shutdown relay the one from the ECM.
ECM issue?

My '97 had its distributor rotor break last year causing it to die while driving and then crank but no start with fuel and no codes. $10 part.
Holy Cow! I kinda expected the plastic to be what broke. Anyway, How old is that old one?
Have you tested the new one? Measured the ohms? What brand? New parts these days are garbage.
I put a Holley Accel rotor, cap and coil on my 97 and Summit 8mm wires.

I think everyone overlooked this? I don't think it can run without the ASD closing.
About 10K miles on it as I recall. Haven’t seen that before but now I keep a spare in my recovery bag.
Go look at the FSM and follow the test procedure for you coil.

Cranking with fuel and no spark, first thing that comes to mind is the crank sensor. Just happened to me on my YJ.
