A few weeks ago I ran into a no spark/no start condition with my 99 Cherokee se.
I changed the ignition coil, plugs, wires, distributor cap, and rotor. - nothing.
So last night I thought that I had it figured and I installed a new crank position sensor, this did the trick! My jeep had life! .. I drove it around for about an hour with no problems.
Until this morning... out of nowhere back to a no start/spark condition.
Any ideas?

Start by checking the wires to make sure they didn't melt. It's common if they aren't routed correctly. If it isn't that, try starting it in Neutral instead of Park to rule out a bad Neutral Safety Switch.
i have a 98 xj with a speaker system with 2 12' subs and a 500w amp. it will start and run, but my volts will dip way down and my radio and subs will shut off, my headlights will dim, and my wipers will slow down. then my jeep will not start. but if i let it sit for a few hours it will start right back up. somebody please tell me whats wrong

Explain this one. 89xj 4.0 w tow package and abs. Because of abs is has a d35 in the back. In the front it has a hp non vac disco Dana 30 with 3:55 gears.
The brake calipers are the type where there's a bracket and a caliper. And it has the weird bottom ball joints with the insert. I don't understand lol, it definitely appears to never of been switched out.
