To the right , i am assuming to the "full tank" reading. am i right?

if i am right, the wire from the gas tank is sending a full tank signal what ever the content of the tank.

meaning the wire is shorted to ground.
or the sending unit is faulty. there is a short to ground reading between the sending unit.

you can test which one is faulty. remove the wire from the sending unit. observe the gauge. if the gauge would go to " empty" then the culprit is the sending unit. if it stays on " full tank", then the wire is faulty.

WARNING: GASOLINE IS EXTREMELY FLAMMABLE. BE VERY CAREFUL IN HANDLING NEAR THEM.


tnx 4 using fixya,

Why is gas gauge not working correctly since fuelpump was replaced.


Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

Fuel gauge on my 2004 f250 will suddenly drop to empty and it changes the ambient temperature gauge to a really low temperature. It will some times change to the right fuel level after I turn it off and...


IT IS SIMPLE YOU HAVE A DEFECTIVE FUEL LEVEL SENDING UINT INSIDE THE GAS TANK. REMOVE THE GAS TANK AND REPLACE THE SENDING UNIT TO CORRECT THE PROBLEM, ABOUT A 4 HOUR JOB WITH A HELPER.

Gas gauge goes to empty and then full after fillup


very well sounds like the sending unit in the tank. Try running some octane booster and fuel injection cleaner in tank of the truck to loosen any deposits on the float.

HI, MY FUEL GAUGE WORKS BUD ERRATIC, I MEAN IT DOESNT SHOW THE CORRECT AMOUNT OF GAS LEFT. WHAT COULD BE WRONG? THANKS.


In a case like this, the culpret is most likely the fuel level sending unit, which is located on the fuel pump in the fuel tank. In most vehicles, the pump and the sending unit all come in one assembly, which means in order to get a correct reading on the gauge, you'll need to replace the fuel pump. And actually, considering the fact that you have to drop the fuel tank and remove the pump anyway, it's just good measure to change them as a set.

I hope this helps! :)

Gas gauge does't work properly


this almost always stems from a faulty fuel level sensor in the fuel tank. It's a part of the fuel pump, so you have to replace the whole thing at once in order to fix it. If you have around 100,000 miles on it, you're getting due for a pump anyways, so you may keep this in mind. Symptoms for the fuel sender, will be intermittent readings on the gas gauge, when it reads, it's correct, but when it doesn't, you get a low fuel message and the gauge goes to empty. This may have a tendency to do it when the fuel tank is within a certain level; but not at a fuller or lesser mark.

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 Gauge Stuck on Full 98 Pontiac Montana


When gauge is pegged at full, usually means a bad ground. Check wires at fuel tank, wiggle around, maybe one came off. The bad news is it is hard to get to without removing the tank. Sometimes you can reach arm in and get to them. Also check body ground at read of van.

My 01 bonneville oil pressure gauge is showing 120 and my gas gauge is all over the place


HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.

Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gauge via wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.

Please rate and god bless:)
