If the engine isn't in normal operating temp. then you are supposed to rev it up to like 6000 rpm for 30 sec. before killing it. I do the same thing when I wash mine, but I drive it around the block and make sure the engine temp is up to normal before I kill it. That is the way I took what the cold start procedure said to do.

:
1. Turn the ignition switch to the START position and hold (up to 10 seconds at a time) until the engine starts.
2. After starting the engine, let it idle for about 10 seconds, then move the vehicle.
3. After moving the vehicle, let the engine idle for about 5 minutes.
4. Rev the engine to 3,000 rpm, and then let it return to idle.
5. Turn the ignition switch to the OFF position.

The procedure I've read in this forum has you revving to 3K briefly then switching it off, WHILE revving. Then, I assume, as it spins down the vile gasoline is expelled or evaporated from the chambers. True, false, more internet propagated BS?

My flood story
Ok, I know there have evidently been lots of posts on here about flooding. But, there are not a lot of people telling what they did to cause it or how they fixed it. I thought I would share mine for future readers.
I have had my RX8 for almost two weeks now. It was a 2004 CPO vehicle with 19k miles on it. The dealer told me to let it idle for 8-10 seconds before I touched the accelerator. I have been very aware and done that.
I drove my car home from out of town. It was a 100 mile drive solid with no break. I parked it in the drive way. The next day, I needed to move it from our upper circular drive to the lower driveway. I went out, started it, let it idle, put it in drive and moved it. I put it in park and turned it off. Total time running was probably 1-2 minutes. That was around noon that day. At 7PM, I went to get in the car. It would not start. It sputtered at first. Having not read the manual or any advice online about a flooded engine, I tried to crank it several times.
After freaking out, then being pissed off I went online. I came here first, but really found no solution. Most people here either called Mazda or claimed that this car does not flood.
I turned to Google. After much searching I found a comment somewhere about the instructions in the manual for starting a flooded engine. (sidebar for those that claim this engine does not flood: if the manual tells you how to start a flooded engine, chances are, it can happen. Most cars don't have this instruction).
I read the manual. The process to "unflood" the engine was to depress the accelerator and hold the starter for 10 seconds. If it did not start, you then remove your foot and start for 10 seconds. That is where the instructions stopped.
By this time I had flooded it good. Now this is where my upbringing came into play. My father is a career motorcycle mechanic. I have been around many a flooded engine. Of course, those had a carbourater, not EFI, but I knew the drill.
I repeated those steps about 8 times until my car started. 10 on, 10 off with a break of 5-10 between attempts.
Now, when the car started, it was smoking something terrible. Again my experience being around flooded engines helped me not to panic. I drove it around for 10 minutes or so and the smoke cleared up.
I am lucky I did not foul the plugs. I still may have it checked when I take it in for the next oil change. Flooding an engine can allow gas to get in places it is not supposed to be and can foul plugs.
Just thought I would share my experience.
And hey, not everyone knee jerk posts about their problems without searching.

Well, I will be going to a different dealer for service. It is closer and my father (2004 Tribute) says their service is better than the dealer I bought it from.
In fact, I will be using Trussville Mazda who has banner ads on this site for RX8 parts. Anyone bought from them?

Moving a cold car, even after idling for a minute or two, and then quickly shutting down is one of the classic ways folks have flooded the RX-8. To be on the safe side, I always make sure the car is warmed for about 7-10 minutes before shutting down.
Good for you on getting it started though, I bet most of the folks give up after a few tries of starting their flooded car. I recall years ago on my first gen RX-7, took me about 8-10 tries to get it fired up after it flooded (similar procedure, but it had a choke back then). Same thing, big cloud of smoke, but after that it ran just fine.

Mine is an 06/03 build. There are 3 labels under the hood. Two are similar and have something on them about a port code. 030A or something like that. The other says something about modifications made that meat EPA guidlines and then a hand written 10 character code of some kind. That is all I see that looks post production.

I only have two numbers on my car. Guess I cant get the file name that they used.
N3H6-18881-M
SW-N3H60M000 I think..

the first is the part number for a flash with the last digit being the level
second is the actual file name except after H6 it should be an E. letter after the E is flash level. that number is for the original Mflash. new part number and file names have replaced the H with a Z and the number after the H for auto/manual has changed.

Well, I joined the mass of "floodeds" this week. I came back to my garaged 2004 "8" AT after a winter vacation of 8-9 days. The starter cranked, sounded like it was going to catch for about 1/4 second, then just spun. All the clearing stuff of foot to the floor didn't help. Charger overnight boosted battery but to no avail. Off it went this morning on a flatbed, thanks to Mazda RoadSide service call. Car has 14 months on it and 17,237 miles of trouble -free driving pleasure. I have no idea what Flash my ECU is but suspect that the battery issue is the key in this case.

Same problem for me in S. Jersey, I have submitted a certified letter to Mazda under the Lemon Law, and an fyi, supposedly the cut off for the Lemon Law is 18,000 or one year.
