I just wanted to say there was about 3 weeks that went by that my 8 sat in the garage. I tried everything...battery,ignition coils,wires,spark plugs, etc. I jumped on here and found a million problem solving techniques on flooding. To be honest, I guess most probably would have worked, but I tried a few that were just not gettin the job done Then I came across one by NYWoody that worked perfectly.
I don't want to steal the thunder but I did want to re-post so that everyone that has tried just about everything could stop here at this post. This is definitly for a severely flooded engine.

So kinda like NYWoody said (but with my own twist).... get yourself some good music, a 13/16 sparkplug socket a rag and maybe a stiff drink, this could be awhile!

(Be sure your engine is flooded before having to go through this!!)

1. Remove the Fuel Relay Fuse, the Circuit Fuse and the Fuel Pump Fuse.
(the circuit and fuel relay can be found in the fuse box under the hood at the very bottom left hand corner.)

2. Jack up the front left side of the car, remove the front left tire (it's easier to get to the plugs that way) and remove the plugs.

3. Spend some time cleaning the plugs very thoroughly ( I used an old tooth brush and some brake free) and make sure to completely dry them off when your done. Be extremely carefull not to brake them (they're about $30 a piece)

4. Here comes the fun part... Get in the car (music blairing in your ears of course) press the accelerator all the way down and turn the key to "ON" Now try and start the car for about 5-7 sec. Keeping the Gas to the floor, wait about 20-30 seconds and try to start the car again. Repeat this process for about 10 maybe 15 minutes. (Or about 3 songs)

5. Now get out of the car and check the holes from the spark plugs. You will have to clean all of the gas and oil from inside and around the holes to make sure you get a good clean area.

You will have to repeat steps 4 and 5 a few times until you have no more excess gas and oil coming out of the holes.

6. Put the spark plugs back in, the wires over the spark plugs and all fuses back in. Turn the car to the "ON" position and leave it there for about a minute or so. This ensures the fuel pump and everything has been "primed" Now simply try to start the car normally. You may have to give it a little gas to keep it running.

If your car starts then dies again, you may have to repeat steps 3 thru 5 all over again. But keep at it. Im sure if your engine is flooded, this process works. It took me about 2 hours, but it was all worth it!!

 

Wow, thanks! I am sure none of this information is available on our website using the search button!

 

Towing it for half a block is a lot easier

( unless you have an auto )

 

How did it get flooded in the first place..............that's what I want to know.

 

I found all that crap to be a waste of time

just made sure battery was good, jumper car hooked up and just rolled it over for 8 second intervals with my foot floored on the gas pedal with 20 second breaks for the starter to cool, 8th try lifted my foot and it ran

 

Good luck if you really flood it......You will cook your starter long before the wet/fouled plugs will start.

 

Well i freakin pulled the car out of a parking space at the hospital and drove it closer to my wifes car so i could put some stuff in it when she was having our baby. I wasnt really thinking, without letting it warm up i just shut it off. Had to tow it back to the house where the fun began. My starter seems fine, although this method will take some miles off it ya know?! I tried a lot of other things like what was mentioned and I couldn't get anything else but this to work.

 

Uh hello? Did you read my thread, which is very similar to what you did. However, you need to disconnect the eccentric shaft position sensor before the "purging" process. Also, when you're finally ready to try to start the engine, you should just press down on the accelerator (to prevent fuel injection) and crank for about 1 to 3 minutes. Then finally release the pedal and crank again. It will probably fire up or almost fire up immediately.

 

This is the good one too from DIY Deflooding in under 5 mins

That is the DIY that you DON'T want to read. For people who have just flooded their car, do you think they want to go through all that? The first part of the stupid DIY is simply go do the Mazda deflooding procedure. Uh, thanks for telling me that.

That DIY should be retitled "How to get ready for future flooding"

 

Hey, I didn't mean to ask the question with the intent of making you out to be an idiot or anything.
I've had mine for two years now and never flooded(Thank God) and don't want to ever have to go through this whole thing!
So........ I'm just merely compiling the data somewhere back in the dark resesses of my mind when I hear these flooded things, just so that I see the different situations where people cause it to happen.
The reality is that this shouldn't even be the case ya know? It kinda sucks in a big way that we have to deal with it....even though it's really not a big deal until you forget!

 

This is basicly what I had to do with a old series 1 Rx7 I had about 10 years ago, pull the plugs, kill the fuel pump, turn motor over, refit clean plugs.
But the rx7 series one didn't have a flooding problem--- had oil control seal problems, was fine when hot, but if you let it sit and cool down eg 4/5 hours, out the with plugs .. etc..etc, haven't had to do this with my rx8.
My 2c worth

 

Thank you for this. This morning I went to start my 8 for the first time since Novemeber!
I've never experienced a flooding issue, partly because I am always very careful to let the car warm up before I shut it down, and partly because I'm sure because it's a S2...but regardless the reason when I went to start it, it sputtered and shut down and would not restart.
I had great starter and battery performance so I decided to try the above approach. After the 2nd try with the gas pedal down and starter going for 8sec. there were signs of life so I kept on trying, and just like it said, around the 7-8th attempt I had a full restart.

The exhuast was cloudy with a slightly blue colour (incompletely burned fuel I imagine), but quickly cleared up.
I have my 8 idling in the garage now and all seems to be okay.

 

Guys yesterday I was driving my car on a highway, and engine suddenly stopped, it was my luck that it stopped at near a shoulder. So I pushed it there. There was smoke from the hood, from the coolant container. I waited for some time for it to cool down and then I poured some coolant, and also it had very small amount of engine oil, so I poured around 5 quarts of it as well. Then I tried to start it, it was not starting as the battery was also dead, then toll road assistance came there and the guy gave my car a jump start, it was cranking but the engine was not starting, and as I pressed the gas after a while of charging my battery, it started but the silencer was smoking really bad as I was pressing gas. And it turned of, every time to start it I had to charge the battery for a while and again same things happened. Can someone help me in guessing the problem.

 

Flooding doesn't suddenly happen when driving.

 

i just had the problem. Did his methods. It worked great. Thanks bro took 5-10 mins
