I have a 91 Cherokee. It had been stalling intermittently starting about 4 months ago, started happening once every couple of weeks but gradually got more frequent. Sometimes after stalling it would start back up sometimes it would not. After a bunch of research and testing I thought I diagnosed the Crankshaft postition sensor as the problem, replaced that with a new one. That was on friday, and since then it has stalled while driving 4 times, twice it fired back up, once it took like 30 min. untill it would fire, and once I had to leave it and come back the next day and it started.
I am just looking for suggestions as where to look next before I start throwing parts at it. The symptoms of the stall are that it just completely cuts out, It doesn't bog or buck like it is not getting gas, just dies.

Here are some parts that are either new or relatively new to rule out.
-crankshaft postilion sensor
-fuel filter
-plugs,wires,cap, rotor ( 1 year)
-fuel pump(1-2yrs old)

Thanks for your help.

 

try your ignition module not sure where it is on the jeeps not much experience yet but i had an 84 chevy that did that

 

is there any way to test that without just putting a new one in

 

1. clean yout tb make sure no gunk is in your throttle body on the butterfly or in the bowl(the area under ther butterfly)

2. check for cracked or leaking vacuum lines (esp. the map sensor line)

3. make sure your tps is adjusted correctly.

4. make sure your distributor cap and rotor and wires aren't causeing the problem.

good luck

 

x2. Especially the TPS. I replaced mine a while back because it was causing a similar problem. Found out you could just remove it and reset it manually until you have a chance to replace it.
