I have a 1994 saturn sl2 and the fuel gauge is not working and stays on empty, in addition the gas indicator light may not work, what do i need and how do i replace it?

The fuel sender is in the gas tank. If the gauge stays on empty then the sender may be bad . If the gauge reads anything else the wire between the sender and gauge is open. A bad sender can also give the same indication.

A common problem with older Chevy trucks is the fuel level sending unit. This is located in the fuel tank and is very likely your problem.

possible fuel sending unit for the gauge check engine light try putting on a new gas cap.. sounds funny but if its the original and its bad it will trigger the check engine light wow i cant believe they told u to use a differnt gas b/s hope i helped good luck

check fuel filter if it clog or fuel pressure regulator...see if you got fuel pressure

It sounds like the fuel sender is bad in the fuel tank.

Assuming nobody stole all of your gas, the fuel level sending unit is bad, the wiring to it is bad, or the instrument panel is failing.

The wiring can be accessed inside the trunk, on the left side, by pulling the carpeting up. The sending unit should read about 35 ohms when full and 235 ohms when the tank is empty. My Haynes manual says the wires are Purple, and Black-White.

If the sending unit reads correctly then the wiring to the instrument panel, or the panel itself is malfunctioning.

If it is the sending unit: the sending unit is attached to the fuel pump inside the fuel tank. You must remove the fuel tank to replace it. While you are in their you might as well put a new fuel pump in.

Try checking and making sure you are getting fuel to the fuel rail there should be a serator valve on the line on the engine. If you are not getting fuel to it make sure the fuel pump fuse and relay are in good working order. Check and see if you can hear the fuel pump running. If you are not getting fuel to the rails and can not hear the pump running the pump is possibly bad.

replace tranny filter and fluid, do not do tranny flush, could cause more problem. just filter and fluid change

yeah replace the odomitor cable that should hook into the side of the trans by the fire wall. also check the fuel tank float and fuel pump

The problem is with the sensor inside the gas tank since the method of indication used is by passing an electric current & the resistance to that current is a measure of level of liquid in the tank , i.e. the gauge consists of two parts:

• The sensing unit
• The indicator

The sensing unit usually uses a float connected to a potentiometer. As the tank empties, the float drops and slides a moving contact along the resistor, increasing its resistance. In addition, when the resistance is at a certain point, it will also turn on a "low fuel" light on some vehicles.
However if this float gets stuck to the bottom of the tank or a leak fills up the float making it sink to the bottom of the tank, thus always indicating 'E' for empty.........................sodeep
