To unflood an engine, first, stop attempting to start the car to prevent further flooding. Press the gas pedal completely down and hold it. Then, turn the key to start the engine and keep it turned for about 5 seconds. Do not pump the gas pedal. This signals the engine control unit to clear the excess fuel. If the car doesn’t start, wait a few minutes and try again. Remember, patience is key, and repeated attempts without waiting might worsen the situation.
