96 Grand Cherokee - Stalling... Replaced CPS .... Different stalling
 

96 Grand Cherokee.
196K miles on it.

It was intermittantly dying with the RPMs dropping to zero immediately.
No rattle, no shake to suggest anything other than electric problem.
After investigation and error code 11, I decided to replace the CPS
(crank position sensor).
Bought the part myself, but didn't have the right tools to install.
Gave it to a mechanic instead.
Picked it up after labor done, started up fine.
However, on the way home, it died again. Can't get it started.
This time, there was sputtering before it died.
Not an immediate shut off.
Then couldn't get it started again, and it was catching and sputtering
unlike the stalls before the CPS was replaced.

Waited about a half hour, tried to start again, and stars up and runs
perfectly. I haven't tried to start it again for fear of it dying on
me.

Any ideas???

Could it be possible that the sensor wasn't installed properly?
Is there a way that the sensor gets heated up and doesn't work
properly?
I don't think it's a fuel pump problem.
I hear the pump start with the key turn.

Thanks much

If it's the 4.0L like the Cherokees then unplug and re plug the cps back by
the firewall. they are known for bad connections there.

Re: 96 Grand Cherokee - Stalling... Replaced CPS .... Different stalling
 

Already tried that. No dice.
It will start when cool. I let it run in my driveway and it ends up
starting to sputter after about 15 to 20min of running, and then dies.
Can't start back up. Have to wait again until cool down.

All I am getting is a error code 11.
