Yes, I have noticed that the gas gauge is never accurate. I have a trip meter on my dashboard. It has become a habit to reset the trip meter when I fill up. I average 22 mpg, so the 15.5 gallons tends to give me roughly 341 miles..but I always fill up around 250 miles...that's the Most I'm willing to do to fix the problem. I think to fix the problem, you have to have the mechanic pull the tank and replace the fuel buoy inside. (Very Expensive Job) I'll just keep doing what I have been in the past...
Its not very expensive or difficult. My husband and I just removed the fuel pump from the trunk, you don't have to drop the engine. And we got a fuel pump, which does not come with the sensor anymore apparently, then we replaced the sensor. All was easy to do, my gas gauge still is not working, but I won't take it to a mechanic just yet.Its not very expensive or difficult.

sounds like a faulty sender unit or your just realy low on fuel before you spend any money on repairs try filling the tank up with fuel as if its been low for a long time the sender unit in the tank may be sticking the fuel will lube it and may start working again
There most likely isn't a problem. The fuel gauge works off of a reisistor board that's mounted on the fuel pump assembly. There is a arm with a float attached to one end. On the other end there are needles that touch the resistor board. The float level changes where the needles touch the risistor board and that changes your fuel gauge. Not all resistor boards read exactly the same, especially if an AC Delco pump wasn't used. The gauge is just reading off a little bit compared to your original one. Try filling up, resetting your trip meter and then driving a good bit. When you fill up the next time figure your gas mileage by dividing the miles you went by how many gallons you used. I bet your still getting around the same gas mileage.
theres two plugs on the fuel pump. one is for pump and one is for gauge if you take pump out of tank and put a volt meter on the two outer prongs in plug then the two inner two of them will read the same when yoou move the level up and down and when you put meter on other two it will change when you move level or the level part of pump isnt working correctly. my old tahoe did that and when it would get to a 1/4 of a tank i knew it was almost out of gas.
I can only think of two possibilities: 1) The Ground Wire (goes from the sending unit in the fuel tank to the frame of the car) is not getting a good connection or 2) The fuel gauge in the dashboard is bad.
If your description means that the change in the gas gauge is random then check the ground wire. If you have a volt-ohm meter, try checking the resistance from the wire where it attaches to the sending unit, negative side. Remove wire from sending unit first. Make sure negative wire on V_O meter is connected to frame of car. Reading should be almost zero. Anything else and the wire you are testing does not have a good connection. If your description means that you turn the car on and the gas gauge is reading full for awhile and then goes to empty, the gas gauge is bad.
Same thing happened to me. Keep an eye on your trip meter for gas usage, otherwise, change the sending unit.
I lost track of mine and ran it bone dry, causing the sending unit to overheat and quit working. Pain in the *** to do it yourself but cost effective. My Step by step instructions are in another similar thread. Hope it doesn't happen to you that way. It's an '03 Malibu, so it was going to happen anyway.
hello! there, fuel gauge not accurately reading or registering your actual fuel,this can spend costly so much on refueling of gas due to worries on drying of tank.there are factor to check on fuel sensor this maybe malfunction,or check the fuel lever sensor this was located on your fuel tank,This should be done on car service center
not by yourself this is due to hard work besides fuel is flammable in small spark of igniton by a certain object.be sure to take all necessasry precaution on doing this.so its beteer qualified mechanic to this.thanks and regads..
is the tank venting correctly and is the gauge reading correctly install a scan tool and read the gauge for proper operation and the vent solnoid kdc744
