#246 of 275 1992 Jeep cherokee, want crank by forhisglory07

Sep 12, 2011 (7:02 am)

I have a 1992 Jeep Cherokee, 6 cylinder. It was running fine, then noticed at times it wasnt wanting to turn over, so i would turn ignition switch off, then try and it would crank. Friday, went to the store, fine, came out wouldnt crank. We replaced the ignition (with key) cranked up, ran fine for 2 days. this morning i get gas, turn off engine, want crank or turn over, the lights, horn, etc all work. the dash gages come on. but want crank. could it be the Ignition switch? If so, where is that located> in steering column or in hood? HELP !

Have the same problem with my 2008. Put a new starter in today. Not the problem. The guy who towed my vehicle suggested some type of relay problem. With a 1992 you may want to check the wiring to the starter for corrosion or bare/worn wire(s). Be sure and disconnect battery before messing with the terminals on starter. Another possibility is the neutral safety switch (NSS). Won't allow the car to be started if it is not working right. Good luck. From what I have seen with these Jeeps you are going to need it.

Have you checked the IAC Valve for carbon build up? You may want to have your TPS tested as well. Both are located in the throttle body. If the IAC has alot of carbon built up on it, I would replace it first, or buy some sensor safe cleaner to remove the carbon. Cleaning out the whole throttle body out makes a big difference.

If the IAC has alot of carbon built up on it, I would replace it or buy some sensor safe cleaner to remove the carbon. Cleaning out the whole throttle body would be even better. I just did this on my Jeep and helped alot!

If it wants to stall when you stop at lights/or just stop and go, it is most likely one of the o/2 sensors. Is there a check engine light then just get the code checked to verify that it is a sensor issue, then replace the sensor that the code tells you is bad.
 
The symptoms you are describing have more than one solution. There could b e a jammed pinion on the AIC valve, you could have a blockage in the air intake and a filthy air filter. SO, 1st-get your code (if any) checked out. If it is an o/2 sensor have it replaced, If it is still acting up then you need to concentrate on the MAF and AIC as culprits. Good luck! -Chris

If there is a check engine light on your dash when it wants to stall when you slow to a stop, it is one of the four 0/2 sensors has gone bad. have that replaced first, but beware! There are FOUR (4) oxygen sensors on the WJ model Jeep you and I both have. (I just had this done by Merchants Auto repairs, I had to have ALL 4 of my sensors replaced. Cost me $375. Mine is finally fixed!
 
It is going to cost you $250 for the new sensors, then a separate fee for someone to install them for you. I would ask a friend who may be a good mechanic and then just slide him 200 bucks to put them in,

My experience is that it is either spark or fuel. Check the spark first it could be the distributor or cellonoid, unplug the distributor wire to the cellonoid and stick a screwdriver in there and start and see if there is spark. If it isn't spark then spray some starter fluid in the air flow and start if it starts for a moment then dies then it is most likely a fuel pump relay or a fuel pump. Hope this helps.

#254 of 275 Ignition we on 2001 Cherokee Sport by cski

The 2001 4.0 liter Cherokee uses a distributor-less ignition system that utilizes coil packs and is controlled by the Engine Control Unit...(ECU). Make sure the plugs are all good, make sure the intake is clean, and the fuel pump is working (u should hear a very slight whine from the back if you turn the key to the on position.w/o starting the engine). It should be throwing a code..so there should be a check engine light on. f so, then take it somewhere for a free estimate. I think its your ECU,and a refurbished one is about $2 - 3 hundred. If the shop buys it it will be $1200. So, my money is on the computer. Good luck. please post back when you have it fixed!
