How to Start a Flooded Mazda RX8


The rotary engine of a Mazda RX8 tends to saturate easily if the car turns off before the engine warms. Flooding the cylinders by injecting excessive fuel into the combustion chamber causes the fuel/air ratio to become disproportionate. When this happens, ignition cannot occur, and the engine cannot start. Dealing with this quirky problem in your Mazda RX8 can be frustrating; often steps taken to try to start a flooded car will only aggravate the issue.

  • Depress and hold the accelerator pedal and crank the engine for eight seconds. This will clear out any fuel that has flooded the combustion chamber.

  • Release the accelerator pedal and start the engine. It is not necessary to press the pedal again. The engine should start without adding more fuel.

  • Let the car sit and run for several seconds. There maybe some smoke; allow it to clear. Do not press on the accelerator pedal again until you are ready to take off.

Tips & Warnings

  • Attempt to start your Mazda up to three times, turning your key and allowing your engine to crank for no more than eight seconds but not less than three. Wait at least three seconds before trying again.
  • Warming the engine prior to turning it off will help prevent future flooding. Once the engine starts, let it run to make sure the engine has warmed before turning it off.
  • Purchase a battery with the highest cranking amp. Extra cranking power can keep your engine from flooding.
