How do you remove flood mode?

Remove the spark plugs and leave them out to dry. Once you've done that or once you install new plugs, you need to start the engine in a special way called “clear flood mode”. On a fuel-injected engine, if you depress the gas pedal, usually past 80%, the fuel system goes into what's called clear-flood mode.

Can spark plugs get flooded?

This happens when there's too much gas and not enough oxygen in the engine, causing the spark plugs to get wet and making it difficult to ignite the fuel. This is one of the most common problems for carbureted cars.
