SOURCE: Jeep Headlights not working. High beam works
had the same problem on my 92....check under the hood on the drivers side,towards the front,there is a "junction box" with all of the lighting wires connecting from the switches to the lights.My wires were all corroded inside,so I cleaned the ends and bought a new box from the local electronic supply store.The problem has not come back.
Cheers

There could be two problems here:
1. That buoy floating tank is not working properly
2. That the electrical system that fails to submit the dashboard.

Good luck... and remember rated this help.

I hope help you with this (rated this help). Good luck.
Hello! There is a sensor ground wire ...Color is Black/Light Blue (pin#4 of a 22 pin connector on the PCM which is sensor ground...That is the same wire multiple that feeds ground to the fuel pump unit (a variable resistor that senses whether the tank is full or empty)...When the vehicle heats up this ground which is more than likely corroded or rusted becomes resistive and opens...The vehicle has some years on it and it's not uncommon for ground straps to rust through,,,The gauge drops to empty...This tells the system; "I'm out of gas" and Sets the fuel level sensor signal to the PCM shutting down the engine...
Your going to need a multimeter (preferably digital) and a wee bit of experience using it...If your not up to this just send a comment and you can then take it to a mechanic and describe the problem specifically...
If you have a meter ( home improvement stores sell them for under $20)...Here are a couple of test procedures to narrow down and solve the problem...
There is a four wire connector that comes out of the top of the gas tank that may be to difficult to reach...Wire colors are...Black...Dark Green/Black...Black/Light Blue and...Light Blue/Yellow...The wire you are interested in is the "Black/Light Blue"...This is a chassis ground wire...There should be Ground straps on the frame...With the meter set on X10 ohms scale... Search under the vehicle for that section of wire harness comming out of the top of the gas tank that contains the above mentioned colors...When you find it ...push the point of a safety pin into the Black/Light Blue wire...Clip one meter probe to it and the other probe to bare metal chassis ground...Or make that probe wire long enough to touch the negative battery post...You must read zero ohms or very close to it...Record reading...Next clip one probe to bare metal chassis ground (a bare fender or firewall bolt...The other to the center of the negative battery post...Meter set the same...Record reading...Next move from chassis ground to the engine block (bare metal)...Record reading...Send results to Saailer
