This is typically a problem with the fuel level sensor that is integral to the fuel pump, in the tank. the only way to repair this issue is to remove the fuel tank and replace the pump. this is a common issue on GM's. the level sensor is a potentiometer, and with wear and tear the "wiper" electrical contact just wears out. you can also try having the vehicle scanned for codes, to eliminate the possibility of another electrical / computer problem (unlikely). good luck!

THE FEUL GAUGE ON MY 2002 BUICK LASABRE DON'T WORK. WHAT COULD THAT BE?


You can typically expect that the sender unit in the fuel tank has failed and requires replacement. You can sometimes access this from an inspection panel, beneath the rear seats and carpet, but often you have to drain and drop the tank out to get to it.

My gas meter doesnt tell the real gas amount. what do i do?


The fuel sender is part of the fuel pump module.the gas tank has to be removed and the module and fuel pump replaced..usually the gauge sender failure means the fuel pump failure is not far behind.On alot of GM vehicles,the fluctuating gauge will trigger the check engine light.

What would make a 1993 buick lasabre act like its not getting gas would tht be a fuel filter


Your vehicle has fuel injection which requires an electric fuel pump. If your vehicle is not getting any fuel I would suspect the fuel pump over the filter. Make sure you have voltage at the pump.

How to replace a fuel pump on a 1995 buick 3.8 lasabre Thank you


The fuel tank must be drained, fuel lines and vent lines disconnected. Disconnect the filler tube that leads to the filler neck. Unplug the wire harness that leads to the top of the fuel tank.
Remove both straps holding the tank into position.
Remove the gas tank and the pump is located in the fuel sending unit that is accessed thru the top of the fuel tank.

The tire shake may be a tire that is out of balance or a bad outer tie rod end. The tank has pressure on it and when you take the cap off the pressure is relieved. Try putting the nozzle in not so far in to pump gas.

Can I remove the fuel gauge from another complete fuel pump assembly and put it on my fuel pump assembly? That is all that is wrong with my fuel pump assembly and a mechanic gave me a used fuel pump a


Yes, if it is mounted to the tank the same way and is from the same type fuel injection system. By same type I mean "port fuel injection" or "throttle body injection". Your system is "port fuel injection" so the used one has to be from a "port fuel injection" system. Also is the tank that the used one is coming out of the same size as yours? If it doesn't hold the same amount of gallons the gas gauge might be wrong. Make sure the the electrical connectors are the same on both assy"s. Hope this helps you out. Good luck.

2002 Avalanche gas gauge problems


Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.
