What causes a car to stall on the side of the road?
Stalling problems trace back to three primary causes: a lack of fuel, not receiving enough air, or insufficient power. Common reasons include an empty gas tank, a faulty fuel pump, a bad ignition coil, fouled spark plugs, water in the fuel, or a failing sensor. An engine stall is never fun.
Can a lack of fuel cause a car to stall?
One of these is the fuel pump, which is in charge of delivering fuel from the tank to the engine. As we mentioned earlier, a lack of fuel will stall a car, causing the engine to die while idling or driving. Thankfully, fuel pumps last a long time, as much as 200,000 miles.

Why does my car stall when I press the gas pedal?
Pressing the gas pedal means opening the main throttle plate, which introduces more air into the engine. The engine has to respond by delivering more fuel, and more aggressive spark timing to set it off. Massive vacuum leaks can cause stalling under acceleration, but more often the cause goes back to a failure in fuel delivery.
The fuel system. Whether it is a fuel quality issue or a fuel supply or fuel injector issue, the fuel system can be the cause of your car stalling. Three things from the fuel system can cause your engine to stall: bad fuel, too little fuel, and too much fuel. When poor fuel quality is the problem, your engine’s combustion process isn’t efficient.

It can cause a stumble, or can cause the engine to stall if it happens consistently. Your engine can stall if it is being starved of fuel.
Can a faulty fuel pump cause a car to stall?
The fuel system. A faulty fuel pump or incorrect timing can cause this. If the engine is over-fuelling, that can cause it to stall. More commonly known as flooding, over-fuelling wets the spark plugs and they aren’t able to ignite the fuel in the cylinder. It causes a misfire that can cause the engine to stall.
Spark plugs are used to ignite the mixture of air and gasoline in the engine at the precise moment it’s been compressed by the cylinder. Old, worn out spark plugs may fail to fire, causing a misfire or even making the engine stall.
What happens when a car starts and then dies?

If your vehicle stalls and won’t start again, but then starts without issue after sitting for a few minutes, it may be a clogged fuel filter.

What to do if your car stalls at a red light?
Fuel pump. If you haven’t replaced the fuel pump in the last ten years, the pump may be worn and unable to deliver the correct amount of fuel the engine needs above idle speeds. Check the fuel pump if your vehicle stalls when stopping at a red light and then starts right back up.
What causes a car to stall at a stop light?
An engine that stalls when you reach a stop light or while idling may point to a faulty idle air control solenoid (IAC). The computer uses the IAC solenoid to bypass the throttle valve and inject more air, depending on engine operating conditions.
What makes an engine stall in a car?
There are three things an engine needs in order to run: fuel, air, and ignition. Ignition means spark, by the way. If one or more of these three things isn’t present or doesn’t happen at the right time, you’ll soon find your car stalling out. The problems that present themselves might be worse than a simple check engine light.
