Nissan Micras ( older style) suffer with flooding too if started and stopped before warmed up. Quick way to sort is -
Remove fuel pump fuse or relay - crank car until it starts to cough into life - replace said fuse/relay and off you go.
Works well on most modern cars where flooded. Trick is knowing its flooded i guess.
Note - doesn't apply to flash floods caused by global warming or cows farting!
