Why are the spark plugs on my car not working?

This can lead to engine flooding, which in turn can soak the plugs so they’re unable to form any kind of spark to start the engine. This often happens in cold weather conditions, when spark plugs that are previously worn or fouled require a higher voltage to ignite the engine.
