You might have flooded your engine if, after several attempts, the car won't start and you detect a strong smell of gasoline. This can happen when too much fuel is injected into the combustion chamber, preventing the spark plugs from igniting the fuel-air mixture. To fix it, try starting the car with the gas pedal fully pressed down, which signals the engine control unit to stop injecting fuel, allowing the excess to evaporate. Release the pedal slowly once the car starts.
