Back in 2004 when I bought a brand new RX8..... 3 days after I bought it it would
not start. I tried all sorts of things but no luck. Called the dealer and he sent a truck
to pick it up. Took him a week to get it started. Mazda then had to re-flashed the EFI program
in all RX8's. That fixed it.

Turns out it is rather easy to flood the rotary engine with fuel.

Recently I had taken the plugs out on the TTC engine and my
helper turned on the Motec and electric boost fuel pump.
Then he pressed the starter button. A lot of fuel vapor came out
of the spark plug holes. NOT GOOD. The Motec was injecting fuel.
A lot of the fuel remained in the engine I am sure.

Then we tried to start it after putting the plugs back in. No way
would it start. We ran the battery down trying.

The apex seals collected all the fuel and oil in the engine and forced
it into the spark plugs holes shorting out the plugs.

The TTC mechanical fuel pump will not supply fuel when the engine is being
turned over by the starter. It is also a good idea to use the emergency
fuel shut off valve and turn off the fuel supply when you are cleaning
moister or fuel out of the engine with the plugs out.

In the past 18 or 19 years we have received many messages where people
found the engine hard to start. I suspect it was the same problem.

Take the plugs out and make sure you do not have a supply of fuel
to your fuel injection or your carburettor. Turn the engine over and
hold a paper towel in front of the spark plug hole. If there is any
wetness of any kind the engine is not ready to start. Only warm
dry air coming out is acceptable.

Once you have that condition the engine will start after you reconnect
the fuel supply.

Same goes for water of course.
