How does a low fuel light work?
The light has one function: to warn drivers of the low fuel level. When the light comes on, there will still be some fuel in the tank, but not much. The low fuel warning light will always turn on when starting up the engine to check the bulb, but should go out once the engine has turned over.

What happens when you run low on gas?
This typically isn’t a huge issue, because it settles to the bottom of the tank. But when you run low on gas, the likelihood of that sediment getting drawn in by your fuel pump increases. This can clog the pump’s fuel filter, which will slow the flow of gas to your engine.
Why does my check engine light light up?
If you’re loosing pressure from gas cap leak the check engine will light up not the low fuel light. Somebody has mentioned about the fuel sensor/sender (?) going bad. I wonder if this is part of the fuel pump/ filter. were any warning signs like this?
Why is my fuel light blinking but I have 2 tank of gas?
Had ML in shop this morning for same problem, after stopping truck and restarting, lite off. System showed no codes or problems, customer indicated hard braking and cornering just before lite came on? The Fuel pump assembly does incorporate the sending unit, which tells your dash and trip computer how much gas is left in the tank.
Why does the low fuel light come on when the tank is full?
All the sudden, the Low Fuel light comes on and the gas gauge is showing empty. I know this is wrong because I just filled up two days ago and have hardly gone anywhere.
Is it bad to let the Gas Light Come On?
It’s still bad for your car to let the gas light come on, however. Gasoline serves to cool and lubricate the motor of the fuel pump, which moves fuel from the tank to the engine.
Running low on fuel can also cause the fuel pump to pick up sediments, which clog the fuel filter, fuel injectors, or high pressure fuel pump. If your gas gauge isn’t working, it’s important to identify the source of the issue, then make a plan for repair.
