ENGINE DIES WHILE DRIVING.

2000 Jeep Cherokee • 147,000 miles

I have a 2000 Jeep Grand Cherokee. While driving the engine just stops, have changed fuel filter hoping this might fix it. It didn't. Any advise for troubleshooting?

Check fuel pressure to verify pressure.
If that is ok, crank sensor may be failing and needs to be verified by someone with a scan tool.

I'VE SEEN THIS CHEROKEE ISSUE MANY TIMES

I'M W/ YOU, ASEMaster6371, ON THE CRANK SENSOR THEORY

THE COOL THING IS THEY'RE NOT REAL EXPENSIVE....I LOOKED UP THIS ONE FOR A 2000 GRAND CHEROKEE 4.7L

MY BUDDY NOW KEEPS A SPARE ONE IN HIS RIG, THIS HAS HAPPENED TO HIM TWICE....THE 1ST TIME, THE DEALER REPLACED IT (WHETHER THE OEM PART WAS THE PROBLEM IS NOT KNOWN) ONE OF HIS FRIENDS REPLACED IT THE 2ND TIME. HE'S NOW RUNNING ON AN AFTERMARKET ONE.

KEEP US INFORMED ON PROGRESS

What type of scan tool do I need and does have to be attached to the jeep or the crank sensor/

A real scan tool, not a code reader. It plugs into the car but unless you have about 2500 or maybe you have a scan tool. Let a shop with the tool check it for you.

Got the sensor out, but lost the bolt somewhere in the jeep. Can anyone tell me how big this bolt is so I can go buy another one?

The bolts that hold the crank sensor in place on that specific jeep are a dealer item only. Its a specific shouldered bolt that you wont find at a hardware. If you ise the wrong bolt you will damage the new sensor.

OTHER POSSIBILITIES YOU MIGHT HAVE ARE A AUTO SALVAGE YARD OR MAYBE AN ENGINE MACHINE SHOP

I DOUBT ANY ONE OF THE THREE WILL "BREAK YOU"---IT'S A MATTER OF THE TIME/TROUBLE IT WILL TAKE TO GET ONE.

I WOULD BE JUMPING UP AND DOWN ON THE BUMPER/ SHINING A FLASHLIGHT EVERYWHERE/ SHOVING A TELESCOPIC MAGNET IN EVERY HOLE/ BUYING ICE CREAM FOR THE NEIGHBOR KID WITH LITTLE HANDS. WITH EVEN A LARGER REWARD SHOULD THEY FIND IT!

Thank you all for all the help. After finally getting the crank sensor installed, had to purchase a new battery, and ended up changing the fuel pump after all. By the way, the bolt for the crank sensor did not come from a dealer. Come from an auto parts store. Thanks for all the help.
