my 88 4.0L cherokee won't start. it'll crank, but won't start. there's no spark from the coil, and the coil is recieving 12 volts. replaced the coil, still no start. had the ignition control module checked, and it checked good. any ideas on what it could be?
thanks
josh

Josh, welcome to . :wave:

Try unplugging and replugging the CPS. The plug's located at the rear of the engine on the driver's side, with a wire harness that goes down toward the bellhousing.

If it starts after doing this, I'd replace the CPS. Common problem with our XJs.

I know this will sound stupid,but any way..my 89, sometimes ,will crank but not start....I pop the hood unplug the TPS,and kinda wiggle the injectors a little...and it will fire right up....none of the injectors is leaking or anything like that.
Another thing...turn the key on and wait a few seconds listen for the fuel pump..I can hear mine if I'm the only in the vehicle...then try to start it

Get a new CPS it's not the plug, that's the way the CPS acts when it's going bad.
