92 jeep cherokee engine cutting out after 30 minutes drive. Random occurrence/highway driving at 45 to 65 MPH. Engine cough/sputtering is dramatic and eventually corrects itself.


Sounds like you may have dirty injectors. Have you tried a good fuel injection cleaner? Lucas is a good product that works. You may have to use it in 2-3 tanks of fuel if the injectors are real dirty.

It would help if you found a shop with a code reader for a 92 Jeep and had them give you the codes. Unfortunately the free code reading service offered by auto parts stores only works on 1996 and later OBDII vehicles. Pre 96 is OBDI, from around 89-95, and requires a different reader or module for each manufacturer. Many shops use a Snap-On reader with different modules, and should have the Jeep module. Cost will vary, but the codes will help diagnose your problem if the injector cleaner doesn't fix it.

Check Fuel pump seal at top of tank. Check carbon canister to see if it full of fuel and or carbon. You will have to disconnect the hoses to it and tip it upside down. Plugged evap hoses from tank to engine. Leaking fuel injector.

92 jeep cherokee wont stay running


Check the fuel injectors and rails for clogging or maybe a seized up ECU. my only other thought is that your throttle position sensor may be shot.

1998 jeep grand cherokee will not start


Try resetting the asd "auto shut down fuse had a similar problem the jeep would crank but did not get spark or gas also check your fuel pump? and the asd relay may be bad it will prevent the jeep from getting no spark and will not fire some jeeps have security problems

My jeep grand cherokee is smoking really bad. Black smoke and it also skips. What might this be?


Black smoke is too much fuel. Bad spark plug, or plugs, bad spark plug wire or wires, bad injector, allow engine to cool, pull the spark plugs. does one look bad? Replace one or all. Plug wires don't last forever. An injector can stick open an pass too much gas :)

PROBLEM WHITH MY XJ 92


Give it a good tune up by replacing the following:

Spark plugs and wires
distributor cap and rotor
air filter
fuel filter

Now add a fuel cleaner to get any water out and clean your injectors. That should do it.

1992 Jeep Cherokee Laredo ... no spark and no fuel pressure


sounds like your crankshaft position sensor has failed it is located on the bellhousing and has a thick black lead off it with a three wire plug, also it should have 1 ten mm bolt holding it in place, this provides an impulse signal for spark and fuel injector pulse and the car wont run without it -jeff ps please rate and goodluck http://www.autopart.com/CrankSensor/CrankSensor1992JEEPCHEROKEE.htm this is also a suspect part but my money is on the crank sensor, this part is this camshaft sensor located in the distributer and will not kill the fuel in most cases just spark http://www.rockauto.com/catalog/raframecatalog.php?catalog=301&partnum=C1929&a=FR301-C1929
