Can the fuel pump be the reason your gas gauge doesnt work?
Loose connections and corrosion can also cause problems, particularly at the Fuel Pump Module, which is usually exposed to the elements. Gas Gauge Failure is less common, but still a possible issue. If the circuit is open, the gas gauge will likely sit at EMPTY and never move.
Why is my gas light on when my tank is full?
Could be as simple as the fuel cap is not tight, or a evap line is leaking. Or because gas gets in there when you over fill it. The fuel indicator flashes for a evap leak when the evap system tries to check tank pressure. This only happens at 3/4 of a tank and 1/4 of a tank of fuel.
Why is my gas gauge going down so fast?
Ray: Actually, you probably just have a faulty gas tank sending unit. There’s a float in your gas tank that floats down as the fuel level drops. As the float goes down, the metal contact attached to it slides down a variable resistor.

Why is my fuel pump not working properly?
It could be due to the fuel pump which will need to be checked. To do this a fuel pressure gauge will have to be hooked up to read the operating pressure. The engine should also be scanned because there might be a problem with the crank sensor which could cause an intermittent running situation.
What does a bad fuel pump sound like?
A priming fuel pump sounds like a high-pitched whine for a few seconds and can be heard with a sharp engine right after the ignition key is turned, but before the starter is engaged. The symptoms of a bad fuel pump match a lot of other common problems that can occur in the Hyundai Elantra.
