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

The cam sensor also is tied into the coil.

I think I would freeze the coil before buying new parts. I also think
the distributor has to come out to change that sucker.

Ok, I know I talk about the stupid body ground lots because I live in
the rust belt and see tons of rotted ones all the time so here goes.

If the wire mesh strap from the rear of the engine head to the firewall
is dirty or ratty, it can cause strange stalls by forcing the
electronics to steal a ground connection. It sure can't hurt to verify
it's connections are good and the mesh isn't rotted.

Our Cherokee acted 'exactly' like it had a dead CPS. It then up and
died within 10 feet of me replacing it. My trouble was a rotted ground
strap.

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

Well, still no resolution to the problem. I replaced the fuel pump,
crank sensor, cam sensor, and even the ECM! It still starts when
cold, but then after running for about 20min starts to sputter, and
dies. Then, you can't get it started again until it cools down. I was
told to possibly check the MAP sensor ??

What about a blocked gas tank vent? That will sure give your symptoms.

I don't know where it is on your vehicle, but if the air filter on the
bottom of my charcoal canister gets plugged with mud it puts a vacuum on
the gas tank and does a nasty immitation of running out of gas. Let it
sit for 10 minutes or so and away it goes again.

The fast test for this is to open the gas cap when it dies and see if it
starts right back up.
