No, a flooded engine typically will not start. When too much fuel is in the engine, it prevents the spark plugs from igniting the fuel-air mixture. A simple fix is to let the car sit for a few minutes to let the fuel evaporate. Alternatively, holding the accelerator pedal down while attempting to start the car can help clear the excess fuel from the cylinders.
