Signs of a flooded engine include a strong smell of gasoline, an engine that cranks but doesn’t start, and wet spark plugs. To fix it, turn off the ignition and wait a few minutes for the fuel to evaporate. Then, press the gas pedal to the floor and hold it there while starting the engine. This will help clear the excess fuel. Release the pedal gradually as the engine starts.
