95 Jeep Grand Cherokee Dies	Sign In

Good Day,
I have a customers 1995 Jeep Cherokee 4.0L that dies. Fuel pressure normal and no codes. When customer had vehicle it dies and sometimes would restart. Finally in their drive way it completely died. Found it was not getting any spark. They had towed vehicle to shop and it has run nearly 6 hours in a 24 hour period and only died 2 times. My initial though was a coil or bad pickup coil in distributor but the 2 times it died here at the shop it restarted and runs great. What are your thoughts? I told customer to let me know if it completely dies again as the problem for sure would then show itself.
Thanks, Fuzzy1

Common and known for failure on these is the Crankshaft Position Sensor on the bellhousing.
Causes intermittent stalls and/or no start conditions.

Thanks for the info. Next time customer calls me with the same problem I will in fact look into the crank sensor.
Thanks so much for your help.
