The symptoms of a flooded engine include the engine not starting, a strong smell of gasoline, and possibly the sound of the engine sputtering without coming to life. If you try to start your car and hear it cranking over but it doesn't start, and you notice a petrol-like odor, there is a good chance the engine is flooded. This often happens after repeated attempts to start the engine without allowing the fuel to dissipate.
