    I told the dealership that was what I thought was the problem- they just ignored me and replaced the fuel filter and fuel pump- I replaced this same item on 1989 jeep I previsouly owned- this is a 2001 jeep grand cherokee and I couldn't find the sensor on it

Hello Howard.
Do you know for sure that it is a fuel supply problem?
This symptom looks to me more like a more common malady to the Jeep line. They are notorious for crankshaft position sensor problems.
What happens is once the defective sensor heats up it goes open circuit and will not reconnect until it cools.
The first thing I would look at when it occurs is does it have spark.
Not sure what year, engine or model you have here.
The sensor is usually mounted at the rear of the engine above the flywheel.
Some are tricky to change due to space problems and you need to be careful with the air gap between the sensor and flywheel on some.

My 1995 jeep will die just driving and sometimes will start right back up other times you have to wait about an hour. fuel pump is working fine you can hear it


The pump can be running but not pumping any fuel.
When it stops running you will need to figure out if you are loosing spark to the plugs or fuel to the injectors.

My jeep cranks but dont start has fuel


Have you done anything else to it? Did you install fuel filter or a shop? You might check too see if it was installed correctly, they fit in a certain direction. The next thing I'd check is the fuel injectors. Does the check engine light come on? If so, O'Reillys and I believe Autozone will check codes for free...

Jeep 96 dies sometime going down the road and wont start sometimes. will start after 10 miles at times and 24 hrs sometimes. the dash says check gauges. help woman alone need advice


Fuel pump intermittent, check for fuel pressure before dropping the tank to renew pump.
Otherwise check electrical connection at battery, and make sure you do not have an open circuit.
Loss of connectivity could cause this issue, failed fuel pump sometimes work, but are not reliable.
You should see 30-45 psi at fuel rail, and the regulator should bump pressure 5 psi when reving the motor. Higher pressure indicates failed regulator.

My jeep keeps stalling on me and the check engine light never comes on, people tell me it may be the fuel pump. i have been told it cant be hooked to compuetr because of the check engine light not com


A stalling problem doesn't have to turn on the check engine light . Try some basic thing's like cleaning the throttle plate (body) air passages for the IAC - idle air control valve . There are videos on youtube , also check for a vacuum leak !

hi if the check engine light comes on i would start by changing fuel filter or fuel pump, however sometimes sensors dont trigger the check engine light and if it doesnt come on i would pull out the cam and crank sensors and clean them as they maybe dirty and causing the spark to die randomly
