Try first using the ignition key to unlock the system , in case this is locked.

If it is not this, then you can reset the whole system by unplugging battery cables for ten minutes.

Ensure you have your car stereo code if you decide to unplu the battery, as you will be asked for security code when you connect back the battery.

SOURCE: 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.

Sounds like the solenoid(s) in the transmission are bad. I'm assuming the engine is shutting off because your maxing out the RPM's in second gear?

Mazda 2 has 105k miles. Why do I notice less acceleration and more RPM change?


If you accelerate especially when using high gears such as the 4th and 5th gear and the RPM is able to increase freely with the speed struggling to catch up with the RPM, it means your clutch is worn out and is slipping.

You need to get the clutch replaced in order for this issue to be rectified, especially if your clutch have not been changed before.

Low fuel pressure on mazda rx8 2008 model, car does not accelerate properly on gets full power after 6500 rpm


You will need to have the fuel pressure monitored under a load with a special tool and also drive it for a while and see if the check engine light comes on, if it does have the system scanned and diagnose the codes received.

96 mazda 626 not shifting into 4th gear


You basically need the trans rebuilt. The only way the speed sensor could affect any of the shifting problems is if it broke off into the trans. somehow. You could try checking the trans fluid first, or having it changed.

Hi to all ihave mazda rx8 2005 model and it start


you have a big issue the cyclinder is firing due to a timing issue. You will need to check if the timing belt, the ignition system is aligned to accurate settings. use a strobe to check for timing result according to the manufacturers setting.Or else you will need to check for defects in valve/cam settings.

Misfiring in 3rd and 4th gear


This sound like a timing issue, Check the points for proper gap, ck for proper timing, also ck the distributor shaft for looseness, or wabble, remove the cap and button and grab the shaft with your fingers and see if it moves back and forth, not in/out thats ok, but in a side to side type of movement. This can cause a missfire at hi rpm.

Water leaking from spark plugh


Hello;
Water / coolant coming from a spark plug hole is not good. However since you have a rotary engine, the probale cause is an o-ring that has gone bad. The older rotary engines were notorious for the o-rings going out. The o-rings seal the combustion, oil and coolant passages. The engine will need to be resealed. Hope this helps.
Thanks;
