What happens when you run your fuel pump too low?
The fuel in your tank helps to cool the electric fuel pump, which frequently generates a fair amount of heat as it runs. Thus, chronically running the car with a very low level of fuel in the tank does expose the pump to more heat than if it was run with a higher level of gas in the tank.
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.
What to do if your car won’t start after running out of gas?
Priming the fuel pump will remove any air that may have gotten into the lines as a result of the vehicle running out of fuel. If priming the fuel pump does not start the vehicle, I would recommend having a fuel system inspection performed by a qualified professional, such as one from YourMechanic.
Why does my fuel pump feel like it is surging?
Irregular resistance inside the fuel pump motor may cause vehicle surging, and indicates a fuel pump in need of repair. Surging feels like the gas pedal has been used. However, it occurs at a random, consistent speed.

Why does my fuel pump start before I crank the engine?
This is normal as once you turn the ignition key before cranking the fuel pump is activated. It has to build up pressure before you crank the engine so it can start at a moments notice.
