I need help on how to deflood the rx-8

 

There is a DIY on the forum here somewhere but if it truly is flooded, I would call MNAO and have it sent to the dealership. The dealership will deflood it, and most likely upgrade the starter, battery, and spark plugs. (along with a reflash if you still have the old one)

If you do a quick search, you'll find how to do it on your own if you really don't want to go to the dealership but then you'll miss out on all the upgrades. (which are free) Have you flooded before? Did you shut the engine off while it was cold?
