The fuel sending unit has gone out. This sending unit operates the fuel gauge. It is located in the gas tank. You will have to remove the tank to fix this. You can try banging on the tank, sometimes the float arm on it gets rusty and will get stuck in one position and the banging will free it up. From your description though, it sounds like the sending unit has shorted out and needs to be replaced.
Please remember to rate this fix.

Fuel gauge stays on full


You may have a unique problem!!! Normally I would say it is the sending unit- in the fuel tank!!!! But Buick LeSabre had a weird thing happen from time to time. Look closely at your fuel guage and focus on the PIN that acts as a stop for the fuel guage to not go beyond the Full mark. Make sure the pin is on the correct side of the pin!!! Sometimes the needle will somehow jump the pin on "E" or "F", and literally hold the needle in place.

Fuel gauge stoped working and the low fuel light stay on


The guage stopped working, because a code set , possibly due to a faulty fuel sending unit, or a wiring issue. This would neeed to be scan tested for the current code. After repair is made, and the code is cleared, the guage will work again. Thanks...

I have a 99 Durango 318 it acts like its not


U may have a defective fuel pressure check valve in the electric fuel pump, u have the classic symptoms, to check this buy a fuel pressure test guage for your truck, about $40, the test port for fuel pressure is on the top of th engine in the fuel rail that supplies fuel to the injectors, hook up the guage to the test port and run the engine, make sure u have no fuel leaks at the hook up, then shut down the engine, the fuel pressure should not drop more than 5 PSI, if it does the check valve is defective and you need a new fuel pump
