Your problem is fuel gauge is hanging up on the fuel pump. The slide bar/fuel sender is located inside the fuel tank alongside the fuel pump. Today I removed my fuel tank and replaced the pick up strainer on my fuel pump and previously my fuel gauge didn't work, but all I needed to do was slightly bend the slide mechanism and my fuel reading read correctly on my gauge. Previous to that I showed no reading on the dash meter.

Youmight have to check if your fuel tank contains water or moisture and results in the deterioration of the unit. There is not much that can be done but to patch up the potentiometer and the readinds may be wrong.
So this time clean out your tank, check for rust wash out and replace. Fill from reputed pumps only
Suplemental Restraint System is the air bag system, When the light comes on there is a problem with the system. The guage could be the tank sender, the guage in the dash, the instrument circuit board or the wiring.
The most likely cause is that the fuel sender in the tank is faulty or that the wiring to the sender is bad.
Less common causes are a faulty fuel guage or circuit in the instrument panel.
Test the sender as it is the most likely cause and easiest to eliminate.
First inspect all connections that are readily visible to insure that they are secure & free from dirt or corrosion.
Disconnect the fuel tank sender wire at the tank. The guage should continue to show full (ignition on). Ground the wire from the sending unit at the fuel tank to any good grounding point on the car. The gauge should go to "Empty". If it does this is a strong indicator that the sending unit is at fault.
if you know the wiring to the fuel guage is ok then could be the fuel sender in the tank,if the ssender is bad youll have to buy one and connect the wiring to the new sender andcheck it if it works fine then you ll have too replace it. if it doesn t then it s in the guage cluster. good luck
ITs nothing atall to do with the fuel!!
some people ?????
check the fuel sender wire for a loose connector at the sender unit on the fuel tank its usaully located on the top of tank in the trunk or could be located on the side of tank [depends on the manufacturer]
the cable going from the gauge to the sender unit is an earth return. if you take it off the sender unit wire if the gauge does read hot the sender and earth it out the gauge should go to the hot segment.dont leave this cable to earth very long do it quickly. if the gauge does read it is ok, there is no earth to the petrol tank. if it does not read it will be faulty. hope this helps.
Very Hard!!!! There are no specs on this, the only way out is to go to your nearest dealer and look at a sender unit and measure its resistance and compare the 2 sender units resistance. It should be measured in Kilo holms, the way to measure it is read the resistance when the floats at its 'lowest' point, and the resistance sould either increase or decrease when you move the float 'up', this depends on what resistance the fuelguage requires, to test if the fuel guage works,'take the positive cable that plugs into the sender unit, fuse it with a low ampeage fuse and connect it to body/chassis while key 'on' and check fuel guage, it must go to full position, there could be another problem, check cables for opencircuits, and check earth(-)connection to the sender unit, plse post to me for further assistance Mishdaman.....
