jeep kept moving the oil filter, and also this part.
on every generation of 5million made.

There is no switch. The relay gets a signal from the computer. If there is no signal from the crank position sensor the computer will not close the relay. If it runs with the relay bypassed, chances are good that the relay itself is bad.

relay should be in the poser distribution center near the battery.

You can get a Haynes '93-'98 Jeep manual ($25) from the auto parts store, in the back you'll find your wiring diagram.

The driver in the computer may have fried. This means PCM (powertrain control module)replacment. First check #26 20A fuse and the automatic shutdown relay in the power distribution center.

Could be one of several items...I'd check the fuel pump relay, auto shutdown relay and the ignition switch itself. I'd bet on it being one of those relays but, we all have been fooled at least once!!! I'd also make sure that body and engine grounding is good and clean. Relays can't work properly without a good ground.

The auto shutdown relay in your vehicle is controlled by the computer. If the computer does not see a signal from the crank or cam sensor, it will turn off power to the relay which in turn shuts off power to the fuel and ignition system. Unlike those in many passenger vehicles, it's not connected to an impact sensor. (as jeeps are off road vehicles as well as being transportation, if they had an impact sensor, they would be prone to shutdown when traveling over rough off road terrain)
The fuses to the relay are affected by shorting or overload of any components they serve, or by a problem with the relay itself.

wall5552: there were two engines used in 1992 Jeep Wranglers.
A 2.5 liter and a 4.0 liter. HOWEVER>>>> The location for the crank angle sensor is the same for both.
It is located on the bell housing up near the front at about the 10:00 PM position.
The Cam position sensor is located in the Distributor on both engines as well.

When I drive my 2000 Jeep Grand Cherokee I can hear water. I was told to blow out the lines of the heater core with a compressor. Where is the heater core located?

Auto shutdown relay and fuel pump relay are by the battery under a cover.
