I need to know what a yellow (!) followed by three low beeps.

Unfortunately, there is no way to get rid of the anti-theft deterrent in the 2004 RX8. The only way to disable it is by using the vehicle's key fob to deactivate the deterrent. If you are having trouble with it, you should consult the vehicle's manual or contact a Mazda dealer for more assistance.

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.

Usually the crank sensor. I would take a really good look at the electrical plug first. The female connectors in the plug tend to spread apart with heat. And wire tend to break right behind the plug.

The rx8 has the rotary ankles engine in it, these have porcelain tipped rotors instead of pistols and are prone to wear resulting in them not starting. The car should start with a bump or toe start. This will require an engine strip down and rebuild and should only be carried out by a qualified mechanic. (Mazda recommend rotors be replaced every 25000 miles)

Let me know if this helps

You already were told by a mechanic what your
cars issues were

Most likely you need a need timing belt or some
sort of engine work

Hi,

my 2004 RX8 has the same problem - can you let me know if you get a fix. [email protected]

Thanks very much

bad trailing plugs or coil packs will cause this problem

Check to see if you are getting fuel to the engine.If not replace the pump relay.Then change the pump if still not working.Check for spark at the wires if you have no spark then change the crank sansor.If still no spark then change the coil pack.

It is flooded. The only way to resolve the problem is to get to dealer to have memory chip reflashed

hopefully you didnt use too much starting fluid. you dont want youre rx8 to be a crack baby. but as ardyrr said it is common for plug fouling and packs going bad. check packs for discoloration on the back side. if present, replace packs. if plugs are fouled replace them too. wires are probably damaged too or next in line to go. and when replacing parts please use oem or performance parts. cheap aftermarket parts will only cause more problems in the near future.
