When your car is cold, it needs a very rich fuel mixture in order to start (rich) means lots of gas and very little air. But if all that gas pours into the cylinders, and, for some reason, the engine doesn't start, the spark plugs can literally get all wet. And when they get too wet, they can't make sparks and the car won't start. That's flooding. When a carbureted car is flooded, you "floor" the gas pedal while you turn the key. That opens the throttle (and, to some extent, the choke), and sends in as much air as possible(I'm shure you already knew this). Ok On a fuel injected car, you floor the gas pedal while turning the key. But what you're doing is sending a message to the computer (which controls the fuel-air mixture). When you press the gas pedal to the floor in the (crank mode)- (when the engine is trying to start), you let the computer know that the engine is flooded, and the computer automatically cuts the fuel flow in half. doing this in repetition however will override the system and cause flooding.
