I have a 1999 Cherokee Sport 2wd 4.0 that I bought with a blown motor. I put a 2000 4.0 motor back in it using all the external parts from the 1999...
NO Spark. I am getting voltage to the plug that plugs in the coil, but no spark out of the coil. Replaced the coil---- still no spark from the coil lead into the cap.
The truck was running when I drove into the garage 4 months ago...although it was missing a piston it would run and make a hell of a racket!
3 Questions----
1- could it be the distibutor? does the distibutor have to be "good" in order to get the coil to fire.
2-I dont THINK it's the CPS, when I unplug it with the ignition on, the check engine light comes on and immediately goes back off when I plug it back in. I also hear all kinds of electicss turn back on when I plug it back in, so I ASSUME its good. Could it still be the culprit?
3-I used the flexplate off the 2000, going back in a 1999.... did I screw this up? I know the 2000 is a distributorless ignition, but it still uses a CPS and the flywheel as a pick up right???
any help would be greatly appreciated!
