Default Jeep Wont Run Need Assistance

I have a 2001 Jeep Cherokee up until today not a single problem ran great. Started it up and got about 5 minutes down the road got to a redlight and the jeep died. It just cranks and cranks I finally got it to fire a couple times but itd die after a few seconds now it wont start. "Update" I got it to run started it up and it runs fine. What should I look at replacing, Thanks in advance this is my vehicle for school.

crankshaft position sensor is likely the culprit

This. It's located on the trans bellhousing, driver's side, pretty annoying to get to but not impossible. If it's not that it's probably the cam position sensor on the passenger side of the block.

Crank position sensor:




Camshaft position sensor:

As it's running now, there are definitely a few possibilities, but that being said...the crankshaft position sensor is the #1 culprit.

If you replace it, do yourself a favor and buy a genuine Mopar crank sensor directly from Jeep. Aftermarket crank sensors are "hit and miss", with a LOT of miss.

Good luck and keep us updated!
