Customer Question

hi i have a 96 Cherokee it dies as I am driving I have changed the pcm and after 3 days of driving the problem occurred again, the crank and cam sensor, cap and rotor, fuel filter,have been changed prior to the pcm, shuts off and has to sit for a while and it will start 1/2 hr or so later
I check for crank signal to coil and not getting signal once it dies
prior to the pcm being replaced it would stop and stall after 1/2 hr driving
after the pcm was replaced it was good for 3 days of daily driving, then reoccurred

Used snap on scanner and there's never been a code cannot get a code and no check engine light that's one of the problems

Okay good thank you .

When you try and start does the RPM show 250 +/-50 rpm ,or is dead and not move at all.

Crank shaft sensor was this an aftermarket or OE.Check on the scan tool in live data for RPM signal .

Customer: replied 1 year ago.
When the car shuts off there's no RPM function when cranky and there are no codes and it's an aftermarket crank sensor
Customer: replied 1 year ago.
It is a 4.0 6cyl.
Expert:  Greg replied 1 year ago.

I would honestly try a OEM sensor first .been down that lane many times .
