Fuel guage always shows empty


It sounds as if the fuel tank sending unit is faulty. This is a small float connected to a variable resistor on the fuel pump/sending unit assembly. Unfortunately this assembly is fairly expensive (over $300) and the fuel tank may need to be removed to replace it.

This problem is caused in most cases by a defective fuel level sending unit inside the gas tank. To replace the fuel sender you must drop the fuel tank out of the car, this requires allot of equipment and a friend to assist.

The problem needs to be properly diagnosed, but the most likely cause of your problem would be a malfunctioning fuel level sensor in the fuel tank. It could also possibly be a problem with the wiring to the sensor.

Hi, take the connector off the temp sensor, turn the key on, and have someone watch the gauge while you insert a paperclip to short the terminals together inside the connector. If the gauge goes from one extreme to the other when the terminals are connected, the cluster is probably OK. It may just be that both sensors are bad.

Dash pannel fuel indicator lamp shows empty but tank full


This would be very common of the fuel pump and level module in the tank. The module from auto zone runs about $280. This must be purchased as a module and replaced. The tank then needs to be dropped out of the car to make this repair. Let me know if you need further instructions to complete this.

97 cadillac deville fuel gauge.


Not a current owner, but knowing Cadillac, that may be the way they meant for you to think of the fuel. How many miles till refill. Maybe that made it easier to swallow the high priced, too frequent fill-ups! I'll ask my friend, he's got a '99.

Fuel gauge showing empty


open circuit in the fuel level sensor. mounted in tank. as the fuel level in the tank starts to drop the arm will move past the dead spot on the sensor and the gauge will start reading again.i dont recommend diy replacement of the fuel level sender.
