It's only in one of the timing notches, and no I have not been able to get it out whatever it is. It's pretty stuck in there, feels solid..

99 XJ 4.0L manual died offroading, due to a melted and destroyed CPS. Replacing CPS turned the no-spark issue into a one-spark issue (only spark is to cylinder 4 from distributor), which is where we are now. The destroyed CPS led me to believe something went wrong in the bell housing. Here's a...

I'm going to see how difficult it is to pull the transmission and get access to the flywheel with my limited work environment. Chances are I'll have to bite the bullet and take this beast to a shop. :( Thanks for all of the help and knowledge everybody!

My biggest question is would this even have any effect on SPARK at all? From everything I've read and heard, the cam sensor functions to synchronize fuel timing with spark, thus it does not actually have anything to do with spark generation...

After reading through the entire article, here's the tip: "Bringing the crankshaft around to zero degrees top dead center (TDC) compression, I removed the cam sensor and checked the hole in the vane where it was supposed to line up with the hole in the housing by inserting a toothpick through...

No, it has a single coil, single crank sensor, single pickup sensor.

Didn't know that syncing was necessary... Thanks for the tip, but that link doesn't work. :rof: There is absolutely no room for crank sensor adjustment. There are two bolts that attach the sensor directly to the bell housing with no wiggle room or anything like that. There is no sign of...

Here's a video of the spark coming from the ignition coil: http://www.youtube.com/watch?v=HILeRjsHxvs and here's a video of the spark coming from the distributor to the only firing cylinder (4th from the front of the engine): http://www.youtube.com/watch?v=O6upD1BGQzU Any ideas?

Thanks again. There is definitely only spark at one cylinder - 3rd from the back. Is there any way to examine the flywheel for damage without pulling the transmission? I'm at college with no place to really work on this thing. During the week it sits in a backyard, but during nights and...

Thanks for the help. How sure are you that this is the problem? I mean it would make sense, but it doesn't seem like the flywheel could possibly be so messed up that it's only send a signal to one of six cylinders.. That just seems crazy. Then again, this is a Jeep we're talking about...

I just looked further into that "weird spark". Here's the deal: The coil is shooting a spark every 5 seconds or so. Right off the bat I realized this was weird... The coil should be firing much more rapidly when cranking, correct? I traced the spark through the distributor cap and it is...

The Cam Position Sensor in the distributor is the same thing as pickup coil - and yes, I replaced that. And yes, there was a bit of moisture under the cap immediately after wheeling. Let it dry out and that didn't do anything, so eventually replaced the rotor, cap, and cam sensor. Basically...

My girlfriend drives a 1999 Cherokee (4.0L, manual trans) and it died when we were off-roading. We checked fuel and air - both fine. We narrowed it down to spark - there was none. No spark at the plugs and no spark from the coil (using spark tester). Checked fuses - all good. Swapped relays -...
