Hi: It Sounds like you Either Have a bad Connection on Your Gauge or the Sending Unit which is in Yout Gas Tank.Your Fuel Pump and Sending Unit Are Located In Gas Tank.Check and Make Sure your Connections are Good and Clean 1st. But it Really Sounds like your Sending unit has Gone Bad.To Replace Sending Unit You'll Have to Drop The Fuel Tank,Empty As Much Fuel as you Can Either Drive till its empty. Holding your Tank Up is 2- Metal Straps with Threaded Bolts and Nuts, Spray with WD-40 And Let It Set awhile Cause Normaly the Are Dirty. Then Take Eiter A Deep Well Socket if it will reach the Nuts,Or Use A Wrench -Remove BOTH NUTS And also at the Filler Tube You'll Probally have a2-3 Screws you'll need to Take Out. Your Tank Should Come on Down.NOTE: Don't PULL the tank out Until you take your Wire Connects Off Remember Which ones Went where. Then Slide Tank out Away From Vehicle, On The Top Of Tank where you remove the wires where thers a Metal Retaining Ring, You'll need to Spray with wd-40 and Remove that Ring,Buy taking a Screw Driver and small Hammer and Tap it out Going Counter Clockwise. After its Off you will be able to Remove the Complete Fuel Pump Assembly. All you'll Need is to Remove Sending Unit.Since Fuel Pump Was Working Right.See if your Auto parts Store has only the Sending unit.if not try Dealership, Hopefully You Won't Have to Replace the Complete Unit. Hopefully this will help you. Please Let Me Know By Voting for me on the Quality of Solutions i've Given you,And Leave a Testamony if You Will. Thanks From The WYOCWBOY

Dorman makes a fuel level sendinding unit $25 online or $40 @ oreilly's. If you pull the carpet up in the trunk you'll find an access panel with 6 speed nuts. Remove lock ring and fuel lines. The only tools necessary are 10mm, flathead, and small hammer.

My 2004 chevy impala fuel gauge go to full when its gets low in gas, can u tell me what makes it do that?


Most likely you have a faulty sending unit in the fuel tank. The sender is a rheostat and can lose its electrical contact in parts of its travel distance from full to empty.

I have 1990 Mazda Protege Se. Gas fuel guage is showing empty but about 2-3 gallons gas is in tank. When I fuel it up to full, gas guage showing full again. What's the problem? How to fix?


the extra fuel is "reserve" to get you to a fuel station... this is normal. If you were to run it completely out you will damage your fuel pump, fuel is used to cool the fuel pump. Soo... DON'T run it so low!

When my fuel runs low, approximately 1/4 tank, my car acts as if it's out of gas and dies. I originally thought broken gauge; obvious, right? However, when I filled it up; it didn't take a full tank. ...


funny that you mention ' Dark Matter ' -- there is a possibility that you might have water contamination in the tank (?), you can try and get some gas additives that remove water from the fuel. also, there is the possibility that fuel pick up line has been damaged and is not getting fuel from as low in the tank as it use to.

2004 mazda 6 with 3.0l V6..WHen the gas guage falls below a quarter tank the car shutters really bad getting on and off the interstate. Almost as if no gas is getting pushed to the engine. Dealer ship said...


Find out how many gallons your fuel tank holds. Once it falls below a 1/4 tank and starts to shutter. Proceed to the nearest gas station and fill up. If you fill it up with 12 gallons and your tank holds 12 gallons then your fuel gauge is off. So it should be reading empty instead a 1/4 tank.

2001 Chevy Impala gas guage incorrect


The level sensor is bad. They are easy to do. You don't have to pull the fuel tank down. There is an acsess hole in the trunk. Look in the rear of the trunk at the rear of the seats. You will notice there is a spot in the middle that the capet comes together, Pull them apart and there is metal plate with some 10mm nuts, pull that off and your fuel pump is there, remove and replace the sensor.
Also there will the a code in the pcm. you will need to clear it to pass emissions

Message center states service 4wd


not sure about the fuel gauge, but I am willing to bet you need a new 4wd switch. This is pretty common on these trucks.

The fuel thing might be a bad cluster. This is also a common problem on the gm vehicles. I have 2 silverados, an impala and a malibu and they all have had funky problems with the clusters.
