Replace the ignition coil.
try to get a new ignition rotor
check the rotor botton in the dizzy
A fouled spark plug, high tension wire breaking down, a bad distributor cap/rotor, coolant leaking into the combustion chamber, etc.
With the new fuel injected engine and improved ignition systems you should be able to go 100,000 before tune-up
With the distributor cap off have some one turn the engine over. If the rotor doesn't turn you broke the cam or a timing gear.
A plugged or partially plugged EGR valve could cause that.
it has to be the distributor cap or rotor or wires...plug wires.
Check/replace Rotor Check for spark at plugs
Bad spark plugs, spark plug wires or distributor cap and rotor.
have you tried chageing the ignition ampifier ?
Every time that a spark plug its changed, the new plug needs to be calibrated ( regularly at .45 ), sometimes the new plugs are not calibrated.
The RX8 has 4 spark plugs or two plugs per rotor. Each rotor has a leading and a trailing plug, the trailing fires a little bit after the leading plug.
try the moduel
You can either take out a spark plug on each rotor and spin it over or you can pull your fuel injection fuse and spin it over.
try to get a new ignition rotor
Could be spark in the motor, or the distributor and rotor need to be replaced.
broken timing belt, check it- you wont get a spark if its broken
