When it quits - Does it crank? Keep spark tester handy to see if spark, also check fuel pressure and pump. Sometimes when a bad fuel pump has been on for a while, it drops out then works again when cooled.

Grand Cherokee stalls when parked in idle or starting through intersection?


I would suggest a fuel pressure test to see if you are getting enough fuel to the engine. If not, then you either have a plugged fuel filter or a failing fuel pump. If you have adequate pressure then something is going on with the fuel injectors.

Stalling 1998 grand cherokee


stalls are complex. over 50 ways to stall any gas engine.
first is not doing a tuneup.
then.
1: lost 12vdc power to EFI system (dash goes dead)
2: lost engine compression
3: lost spark
4: bad fueling. (too much or too little can stall any engine)

early 4L engine has EGR and it can stall any engine.
and on all 4L, he ISC loves to stick.
so the #1 test, is , can you save the stall, with a fast right foot.
no one ever answers this.... sadly.

How to engage the 4 wheel drive on a 1991 jeep cherokee


You can "shift on the fly" at up to 45mph - just let off the gas and pull the shifter back to 4hi. DO NOT try going to 4lo while moving.

Another way is to stop, put it in neutral, and pull the shifter back to 4hi or 4lo.

This is vacuum activated - so if you can't get it to engage - the vacuum motor is failed - or you have a disconnected or rotted vacuum line.

Cherokees have the command - track. You'll see a lever next to the transmission shifter that has letters 2H, 4H, N, 4L on it.
You can shift from 2H (2wheel drive high range) to 4H (4wheel drive high range) at any legal speed.
If it's an automatic, I recommend just taking your feet off of both pedals, so there's not a lot of torque being passed thru the transfer case.
If it's a standard I recommend stepping on the clutch when you shift, but it's not necessary.
To go to Neutral just pull the shifter back one more position to the N position. To shift into 4L (4wheel drive lo range) you must be stopped.
I also recommend shifting the transmission into neutral when you do this. Push the shifter to the right, then pull it back.

Thanks!

Jeep stalls


try doing the procedure below, should cure the problem.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

199 Jeep cherokee stalls without warning


Does it start right back up after it stalls? make sure all conections are tight at fuel pump, sounds like it could be loosing ground at pump, or hot lead is loosing its connection at pump.Also fuel pump relay could be getting hot and quits working.
