2000 Grand 4.0 missing on 2 4 and 6 cyl HELP PLEASE!!!
Hello everyone.
I got a 2000 Grand Cherokee 4.0
It is missing on number 2 4 and 6 cylinder.
I have replaced the coil pack, pcm, crank sensor and the cam sensor.
The jeep came to me and the pcm was from autozone under warranty.
So we shipped it off and they said it was fine.
The coil pack removed will fire on number 1 3 and 5.
It will not spark on 2 4 and 6.
Does the pcm control the firing on the coil pack?
Also is there any testing I can do to see if the pcm is working right as far as correct voltage to the coil pack.
I have read and read but I still havent found what I am needing.
Also the injectors are pulsing correctly.
Thanks for any advice.

Also does the computer have a driver for these cylinders as far as in the pcm?

I tried 2 new ones and it does the same thing.
I ohm ed the old one compared to the new one and it is the same.
Is there a manual on here anywhere that I can download.
I looked at the Chilton at the zone and it shows the drivers for the eight cylinder but not the 4.0
Does anyone have this information???
Thanks!!
