SOURCE: RE: Fuel Gage

The sending unit is the culprit, most likely the arm for the float is detached.

Had new fuel pump put in, now fuel gauge won't work, registers right when you start but goes to e immediately


I need the year--make--model. I can't look up any wiring w/o year--make--model.
Some vehicles will do a gage sweep when you first turn on. On some, the fuel sending unit is monitored by the pcm, the pcm will send serial data to instrument cluster for the fuel level gage. If the pcm detects a problem, the gage may default to empty.
It just depends on the vehicle.

1993 chrysler new yorker. Fuel gage doesn't register. Low fuel light stays on even when tank is full.


More than likely the sending unit is not communicating with the fuel gauge so even when the tank is full the unit doesn't register it.There could be a short or a loose connection from the sending unit to the guage

Wiring diagram of fuel gauge for toyota corolla 2006 - frozen fuel gauge


It is the sending unit, usually the veryable resister and arm. Remove and replace sending unit. It is , unfortunately, located inside of the fuel tank. To confirm gage operation reverse wiring to the guage and it will reverse the guage, confirming tha the gauge.is ok.

My fuel gage registers empty when I just fill with gas


Most likely it is either the fuel level sending unit attached to the fuel pump or the stand alone unit (there are two sending units, both located in the tank), or, as counter-intuitive as it seems, it could be the speedometer assembly. Personally, I lean toward the latter.

Fuel gage not working. Only a smsll light seen. Does the fuel pump need changing?


As long as the car is running fine it's safe to say the fuel pump does not need to be replaced. However the fuel tank sending unit may need to be replaced assuming the fuel gauge itself isn't at fault. First check your owners manual if available for your fuse block info and check fuses then I'd look into the sending unit. Let me know if you need help with that

The gas gage on my 2002 deville does not register correctly. I never know how much gas I have. What are the problem areas to consider?


The problem is either a faulty fuel sending unit located inside of the fuel tank, the wiring between the fuel sending unit and the fuel gauge, or the fuel gauge itself is malfunctioning.

A good repair shop can find out for you which one is at fault by dis-connecting the wiring connector to the fuel sending unit and then use an adjustable ohms box to simulate the fuel sending unit, and the fuel gauge should read at a certain level of fuel according to the amount of ohms being put through the wire.

Fuel gauge not give proper reading.. register full


Sorry to say,but the fuel sending unit is the problem,the fuel tank will have to be lowered out of the vehicle to replace the unit.If the fuel sending unit is not available by itself you will have to replace the whole fuel pump assembley.

Fuel gage


Classic symptom of a failing sending unit. It's inside the tank and on most cars it's replaceable separate from the fuel pump. I usually see them in the $45-75 range. Some cars have an access panel under the rear seat or in the trunk, where others require the fuel tank to be dropped - I'm not sure offhand which your car requires, however.
