Good evening Mr. Lamar and other rotary people,

I have a starting problem with my rx8, 2004, hi-power version. 108 000
KM.
My car will not start. I replace apex seals and all parts which was bad,
but engine not start too.  I replace starter 2004, e-shaft position
sensor, igniton coil + cables, spark plugs, knocking sensor, throttle
body activator,  SSV actuator,. Engine allways wont start, but  when we
pushing car, on 10 metres car start, and car drive ok, but engine has a
unstable idle, 750 -1500.
Please help me.

You need to get an OBD II program for your PC computer and a special
cable that connects to the OBD II connector under the dash.
That will tell you what is wrong.
Obviously none of the stuff you changed so far was the problem.

Thank you very much, but I was on PC in Mazda service. PC tell me that
range of ex.shaft position sensor is bad, and second rotor has not good
combustion.

Well if the shaft sensor is bad the engine will not run.

The latest thinking on early 2004 2005 RX8 problems is the newly designed coils
were misfiring allowing the unburnt fuel to wash the apex seal oil
out of the engine. Check the coils that you have now.
If the part number marked on the side of the coils is not
followed by a "B" replace the coils.

If the rear rotor compression is still low the engine
will need to be over hauled. With less than 100,000
miles (not kilometers) it will be done by Mazda
for free.
