Your problem is common in the RX-8. It occurs when you start a cold engine and shut it off before it reaches normal operating temperature. If your car does flood, you can first try depressing the accelerator completely and holding it (which shuts off the fuel pump) and then crank the motor for about 10 seconds (not longer or you may damage your starter). If this procedure above does not work, here is the technique a Mazda dealership will normally use (to be performed at your own risk): 1. Use jumper cables to connect to another car battery. 2. Unplug Air pump connector (the black circular motor housing to the left of the oil filler cap) 3. Take fuel pump fuse out (number 22, a 20 amp, 3 from the top of the second column of the fuse box 4. Crank for 4 seconds, pause for 2 seconds, repeat for about a minute 5. Leave for a minute 6. Crank for 4 seconds, pause for 2 seconds, repeat for about a minute 7. Put fuel pump fuse back in 8. Crank for up to 10 seconds, if it catches but doesn?t start, stop cranking 9. If not started go back to step 3 10. If started, wait 30 seconds for oil pressure to rise 11. Stand on throttle until white smoke stops coming out of the exhaust 12. Disconnect jump leads 13. Leave to warm up on idle for a few minutes 14. Put air pump connector back on (see note 3) 15. Go for a nice long drive to recharge the battery

If you flooded the engine then you will likely need to put in a new set of plugs,and recharge your battery.Put booster cables to the battery while you are replacing the plugs and then by the time you have them changed it should start.Just in case,add a bottle of gas line deicer also before you start changing the plugs,hope this helps.

Not sure if I flooded my rx8...


if you hold gas pedal to floor while cranking, it shuts off the fuel supply to clear a flooded engine. Try it & report

I started the car for 15 second and then shut it off. when tried the following morning it engine would crank but would not start


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

Engine rolls over does not start


I had this problem. Twice! It sounded like it wanted to turn over but couldn't. Your engine may be flooded. I had to have mine towed to the mazda dealer (if under 100,000 miles it is under warrenty) so they could fix it. The second time they had to replace my engine because of a bad compression ring.

Rx8 car has trouble starting you need to step on the gas 7-10 times for the car to start


The RX8 has always been a bit problematic at starting, at least until Mazda started fitted uprated starters (~2006). The standard, weak starter motor spins the engine quite slowly, causing problems getting compression to start the engine.

There's various things to try...

DON'T pump the gas whilst starting - foot OFF the accelarator (might be beneficial to depress the clutch just to reduce the loading on the starter motor). Check all the RX8 owners' forums - standard advice.

DO use a confident turn of the key - keep cranking until it catches (but not for more than 10 seconds - in which case leave for 10 seconds before trying again) - don't just crank for a second or two, then retry. That's as per owner's manual.

DO ensure that you leave the engine to warm up ALWAYS before shutting off - to avoid fuel being left in the rotor - that affects compression badly if left any period of time, resulting in very poor starting (risk of flooding).

If non of the above helps, get a hot-engine compression check to ensure that the engine isn't shot. If the engine is okay, then consider getting an uprated starter motor, or 3rd-party replacement. Many 2004/2005s have had their starters replaced (I considered mine, although I've had no problem over winter :)

Mazda RX8 starting problem


Check that your battery is fully charged. If it does not sustain a charge , replace it. Clean the cables and battery posts with baking soda and water mixture. About 1/4 cup to a pint. If it still does not turn with a fully chared battery, it is probably the starter that is bad. It will have to be replaced. One click usually means the starter is bad. Several clicks usually means the battery is bad.
