SOURCE: Fuel gauge issues

Sounds like you've got a defective fuel level sending unit. It's in your tank, probably attached to the boost pump assembly. Normally the top of the tank can be accessed via the trunk where you should be able to remove the assembly for replacement. While you're in there, look around in the tank with a very bright flashlight for any debris or pieces from the assembly laying on the bottom.

Horrible gas mileage can be caused by very many things. Try to buy an OBDII diagnostic scanner to figure out what's malfunctioning. Sensors don't last very long, and can wreak havoc on performance and economy.

SOURCE: fuel gauge fluctuates on 1995 chevrolet tahoe

if you replaced the tank and all i assume you didnt change the fuel pump. if you dint then all thats wrong is that the float on the fuel pump is gas logged and will move more than if you had put in a new pump thus the fluctuation in the guage.

SOURCE: gas gauge flucuates to empty and full so we never know if we have enough gas. What to do?

It is a common problem. It is a faulty in tank sender. You can just replace the sending unit by removing tank.

SOURCE: 2000 Buick Century gas gauge reads full all the time

You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.

Why does gas light continue to constantly come on even when full in 02 Buick renedivous


If the gauge is reading full and the light is still on, that sounds like a body control module fault. I would take it to the dealer or other qualified service center for a better diagnostic.

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

My gas gauge is stuck on empty, how to fix


if your gas tank is empty of course the gauge is empty,but if the gas is full and the gauge still empty all you have to do is to check the float valve inside the gas tank maybe it is stuck.Or need to change if necessary.

Gas gage went to empty and low gas light went on and low tire light


Put gas in your car and check your tire pressures. If your fuel gauge just "Jumped" suddenly to empty, you probably have a bad sending unit in the fuel tank.
