Question about 2004 Mazda RX-8
If u start an rx8 without letting the engine heat up fully before switching it off then it floods the engine with fuel, a rotary engine problem, ring the dealer and they will be able to sort you out, is costly though... ALWAYS LET THE ENGINE FULLY WARM UP! before switching off!!
also rev the engine to 4000rpm and turn the key with foot still on the throttle when turning the engine off, to prevent flooding

If you start a rotory engine and dont let it warm up before shutiing it down chances are its flooded common problem. the only thing you can do at home is to hold the throttle pedel to the floor( which cuts out the fuel) and crank for 10 sec turn off and try again the biggest problem is people stop cranking when it starts then the car dies again, keep cranking until the car is running for at least 3 seconds.

Flooding seems to be a common problem with the RX8 engines. The spark plugs are very cold from Mazda (heat 8 leading & heat 9 trailing)
Changing the leading plugs to a warmer heat grade will help with this problem.
I picked up a set of these for £75 delivered after reading this - RX8 spark plug install guide
Hope this helps.

Please a little more info. you started the car for 15 seconds - why did you shut it off? have you had any other problems? An engine cranking but not starting is either missing fuel or spark. The easiest to check is the fuel. Get a can of starting fluid from an auto parts store and have someone spray into the open air filter box while you are trying to start the engine. If it fires then you are not getting fuel and the fuel pump might be the problem. If not then spark is probably missing and you should check plugs wires ditsributor cap and ignition module. if this helps please reply as this helps me keep answering questions here and good luck
