like njoutlaw88 alluded to, your engine is probably flooded. You don't need a tune up though, just fuel injector cleaner. To get it to start, push the gas pedal to the floor for a good 10 seconds and keep it to the floor as you attempt to start the car. Once it starts, keep a steady pressure so that it will not stall and it will burn out the excess gas. Good luck man.
