Question about 1993 Jeep Grand Cherokee

1 Answer

Jeep won't start

Theproblem started w/ jeep starting running about 3-5 mins. then stalling as if the ignition was shut off. I started by replacing fuel filter and doing a tune-up.First thing I noticed was the spark gap was .50 instead of .35. I gap @ .35 per man. specks. The problem persisted, then I replaced the crank position sensor. Still same problem. I have spark and fuel I'm assuming the timing is correct, since I didn't do anything with it. Oh this is a 93 jeep cherokee w/ 4.0L. What's next the ignition control module?

Check voltage at coil. Check coil output (spark should be healthy even at 1/4" away from ground). If OK, then change module The only testing on module is with a special tool. Therefore if contacts are clean, that's all you can do with it!

It would be worth checking/replacing the ignition module ( see if you have a spark when it WON'T start) . Coil assy are plentiful and the most likely given your description. Very prone to over heating and shutting down. Good luck

After driving for 15 min stalls. when i go to start it cranks but doesnt start. after one min of sitting starts right up.repeats every half hour


Sounds like you need to replace the ignition coil,they heat up and go open but when allowed to cool they make contact and then the engine will start.

Runs fine for approx 15 mins,then stalls out and wont start again


sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.
