how to tell if my 2008 rx 8 gt flooded

Bought the 2008 rx 8 gt in september 2014, had it parked since then went to start it today and i could hear the sound of the engine misfire and sputter white smoke out of the exhaust after about 4 minutes i shut the car off cause i seen the engine light flashing. I tried to start it again a couple of hours later but it wouldn't turn over i had pumped the gas at the very last second to see if it would turn it over but nothing. Its winter right now where i live and i did do a cold start. Any suggestions or procedures i can take. Its a manual transmition
