Having problems with your 1999 Chevrolet Malibu ?
1999 Malibu "Fuel Door light" is on and gas needle dropping
\015 I have a full tank of gas and as soon as I pull out of the gas station the gas needle drops down to empty and the "fuel door" light comes on and chimes.\015\012\015\012What is the problem? is it the sensor? I started simple with a new gas cap but it's still happening.\015
Fuel sender is bad or the plug to be sure unplug it from under the car and if you have a ohm meter the pumpside shoud be 40 ohm ety and 250 full the same wires on the bodyside should be 12 volts and ground
I am willing to bet the fuel level sensor is faulty inside the tank.
