YJ Ignition Problem

[Ray VanBuren]

I need help. Last weekend, my '91 YJ, w/2.5, just quit running. Has fuel pressure so I checked the codes. Says "ignition problem". I replaced the coil, cap, rotor, and ECM. Jeep will start sometimes, but dies within seconds. Any help diagnosing this would be appreciated. One thing I forgot to mention is the fact that I pulled the "Auto Shutdown" relay from the PDC after I swapped all the other parts. After a few minutes, I reinstalled it, turned the key, and it ran... for about a minute.

when my 95 yj with 2.5 did this .....
I replaced ECM and .... Nothing ! wasted money !

Cleaned all contacts and fuse connections good and she fired right up and has run ever since.

I agree on the wasted money. One thing I forgot to mention is the fact that I pulled the "Auto Shutdown" relay after I swapped all the other parts. After a few minutes, I reinstalled it, turned the key, and it ran... for about a minute.
