1998 Jeep- Turns Over But Won't Start
Asked by GuruZNP7J Nov 10, 2017 at 11:12 PM about the 1998 Jeep Cherokee Sport 4-Door 4WD
Question type: Maintenance & Repair
Just bought a 1998 Jeep Cherokee Sport as a
winter vehicle and to plow. Ran great for a day and
drove to work. Went to start it to leave, it took a
couple times but started. Let it warm up, came
back out and it had quit. Tried starting it, just
cranks and won't fire. Replaced the coil and crank
sensor. Same problem, cranks but won't fire. It's
not worth taking into a repair shop, ready to cut my
losses at almost $2000 and scrap it. Any ideas or
help? At this point don't want to put much more
into it.

A couple other things, had a computer hooked up and the code was for low voltage to the distributor; and, also replaced the cam position sensor.
Check o2 sensor first... always overlooked and common problem or another guess...and (I'm sorry to say) is fuel pump may need to be replaced.
Thanks! It was actually the new crank position sensor. When it was put in the connection was loose. It's up and running again!
Ok Guy's to all that have this problem. Of crank no start one of three thing's.#1:check plugs for spark none #2check coil for same no spark then replace brain on fire wall engine compartment by overflow and if it still cranking and no start check timing. Worked for me hope it does for u good luck. P.S You can be sure if you're distributior is turning it's not the timing chain or belt it works of the cam and it won't turn if broken.

I replaced the cps in my 98 gc laredo and jeep continued to just crank after about 5 or 6 diff ppl looked with,no luck so I just let it sot for 6 months!! I started reading this very site and decided to see what codes i could see if any and i also put it in neutral might be the safety switch or whatever it's called so after doing the ignition switch thing and moved to neutral back to park it fired right up I almost had heart attack! Man was I happy lol
i have heard a lot of BS about your 1997 jeep Laredo have someone turn over the engine while someone pulls on the brain on the firewall left side facing engine pull on the bottom & back & forth when it starts or hits leave it there it will run i have a stick wedged in mine broke down on side of the road one night & GOD gave me a stick after all the experts said i needed a brain i think they meant for the jeep haha been 5 years every now & then i have to readjust
Check out your nutra fuel shut off switch

Replace TPS sensor, and pick up coil in distributor. Sounds like no spark, also check ignition coil for spark.
