When engine runs out of fuel does it stop running?
You might surmise that when your car runs out of gas the engine simply stops running, but it typically doesn’t happen that way. Most often the car will show signs of “fuel starvation” that include engine sputter, intermittent power surges, and perhaps even engine backfires.
Why do I have to hit the gas for my car to start?
The fuel injection system does nothing until the engine is turning (starting or running), so pressing the pedal before you start will make no difference. The fuel injectors work at any RPM, so a choke is not necessary. The computer simply feeds a little extra gas through the fuel injectors to start the engine.

And some older diesel cars needed to have air bled from the fuel system after they’d run out of fuel.
What happens when you run out of gas in your car?
When you run out of gas it can play havoc with your fuel delivery system. Here is what can go wrong.

That fuel pump uses the gasoline in the tank to both cool and lubricate itself.
What makes an engine not start or run?
All engines require three things to start and run: spark, fuel and compression. If any one of these is missing, your engine will not start. The fuel pump is running and delivering normal pressure to the engine
What causes a riding mower to stop running?
The gas cap should let air into the fuel tank to fill the space that occurs as the fuel is burned. If air is not let into the tank in sufficient volume to keep the tank filled with fuel and air, the fuel tank goes into a vacuum inside. When this vacuum occurs fuel stops flowing out of the fuel tank and the engine dies.
