Gas gauge flashes on and off.

it evaporates normally on hot weather when not in use for long period of time but on cold weather i dont think it will evaporate that much.with 323 sometimes there is something wrong with the gas gauge..

If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

you may have crossed the wires. on the read wire some were but if your pump is in the tank then you have put the wires in the way of the gauge sensor easy thing to do when putting the top back on. just take the top back off and move the wires to the oher side wile holding the top and putting it back on.

it's just either the gas gauge is being faulty

FLOAT INSIDE OF THE TANK , STUCK

file pump

You weren't low on gas - your fuel tank sending unit is failing and needs replacement. It's inside the tank and usually can be replaced without replacing the fuel pump as well - don't get suckered into that.

This is a common problem with Malibu's. It is due to cheap metal in the fuel gage that corrodes. Chevrolet knows about this but they refuse to issue a fix. The check engine light staying on and the faulty fuel gage are related. This is a defect and they need to recall this part! Raise hell with the dealership!

Defective sending unit in gas gauge.

most likley a sticking fuel sending unit in the tank, if it starts happening more consistantly you will have to replace the sending unit
