flywheel issue causing no start?

[myjeepisDEAD]

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 video showing the flywheel (looking through the CPS hole in top of the bell housing). Of the twelve timing notches, eleven look perfect and one has an obstruction. Can't figure out if it's metal or rock or something, but it's definitely not plastic from the old melted CPS. Check out the obstruction toward the end of the video (1:00-1:25).

Check out the video of the flywheel here.

Would this cause a no-start? Seems like a minor issue...

Already replaced CPS, pickup sensor, ignition coil, cap, rotor, ECM. Checked all fuses, relays, wiring, grounds, etc. Something is definitely wrong with the flywheel, just not exactly sure how bad or what.

Did you get that crap out of the flywheel notches?

 

[myjeepisDEAD]

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..

Its apparent that you're in need of taking out the trans and trying to figure out what went wrong. You have two threads about this issue now and know what you need to do

You would think so by now, wouldn't you. Pretty much reminds me of the Black Knight's denial in Monty Python and the Holy Grail.

Yeah, I can understand if he hasn't got the best place or tools to do the job. Who feels like taking the trans out of an XJ if they don't need to. But making more threads about the same problem isn't going to get it out any quicker. Anyway, good luck with the task ahead.

OK, what caused the cps to melt?

( -Just a guess-
VERY HOT clutch/flywheel from slipping the clutch during offroading melted CPS?? (with help from VERY HOT exhaust) ??? )

It will have to be opened up to determine what is to be repaired AS PER PRIOR POSTS.

Any Jeep clubs in area?
