DIY: Deflooding ,For the average Joe the plumber.

Worked!!!
The post worked out for me.....thanks guys....just one note, us old piston heads are listening for certain sounds...ie...compression strokes. At first I thought my engine was toast because all it would do is turn over and I couldn't hear what I thought was the compression stroke....Don't give up!! These Rotary's sound different and even more so when they are flooded...I had to take the plugs out and turn it over several times (could have lit off the fumes of raw fuel..it reaked!!!) then it cranked differently when I put the plugs back in. Must have been a severe flood...My 8 fired right up...Don't give up hope. If you take the plugs out and crank that will determine if you have compression because you can hear it blowing out the plug holes...Thanks guys you saved me again!!!

Mine won't start and the remove fuse and crank doesn't seem to work, neither did the floor the pedal and start method. It may have been shut off cold last time, just from the drive way into the garage and been sitting in the garage for a couple week. I don't do that often, and that has never been a problem before. Car only flooded once by body shop a few years back. I do not smell gas at all when it cranks and the car ran fine before (seals are good hopefully?). I guess checking the plugs is next.
the fuel gauge is at 1/8 of a tank, now with the split tank and all, what are the chances that the pump is not getting gas even the gauge says I do?

Flooding Nightmare?
Hey guys..I feel I must first apologize for the long post
I have viewed these forums for several years. I own a 2005 Rx8 with about 96k miles on it (Lots of highway miles). About 4 weeks ago I flooded my engine. I tried the standard de-choking procedure with no effect. I removed the spark plugs and cranked the engine per mazda specifications to try to clear the combustion chamber. I put in new plugs and wires and still could not get the car to start. I put in new ignition coils and tried the DIY deflooding technique posted on the forums twice and still have not been able to get my car started. Meaning I drained my battery to next to nothing even with a booster car with no success. The second time around I tried spraying a little starting fluid in the air intake past the air filter, again no success. I did this after deflooding and before trying to start it with my foot off the gas. Both times it seems like the car wants to start but then doesn't. No one has said anything about needing to recharge their battery and keep going so I did not know if this could be expected and I need to just keep at it or if there might be something else wrong? Compression perhaps? According to the mazda tech manual about it that I found, if you replace the plugs and clear/deflood the combustion chamber and the car doesn't start then one needs to restore the engine compression. I simply just do not know whether this is something that is done and it is not the problem whether it will be damaging to the engine?

Third time was the charm...I also cranked for 10 second intervals on and off this time instead of 4-5. The car came to life and sputtered down twice but on the third time it came to life and is running like a dream....now I just need grind off all the built up rust from the last 4 weeks
The main thing if you're doing this is to give sufficient time for the starter motor to cool off - the worst thing you can do is burn out the motor.
#106
I have a question...under what state was the car operating before it "flooded?".... How was your car running before this happened?...My situation had me stumped because I too hadn't driven my car for a couple of days. When I shut it off it ran like a dream. Only until later did my son fess up and tell me that he drove it 10' and then shut it off....Remember that Rotary's are a different machine...meaning when they crank they sound different...and...they need to turn over at a certain speed in order to fire so your battery has to be fully charged and that's why I cranked mine with the plugs out and the pedal to the floor (pulled the fuel pump fuse as well)...I would try a couple of things: Replace the battery...if you are cranking it down to nothing all you are going to do is kill the battery and the starter motor...Check for spark. You can do this while cranking...Third...when you replace the fuse for the fuel pump, turn your key to on...stop....wait 4 seconds (listen for the fuel pump to charge you can hear it from the inside of the car but it has to be quiet) then turn it over.....Many times we hit the key and go straight to start and don't wait for the fuel pump to charge...if you hear nothing..then it's obvious...you aren't getting fuel and the pump is bad.
I also tried starting fluid...just a small spray in the intake but while cranking held the pedal to the floor...it worked.

Hi all, I just went through this nightmare as well. About 2 weeks ago, I I wanted to save myself a car wash, so I decided to pull my 8 out of the garage cuz it was pouring. I moved it out, revved it up to about 4K before shutting it down. The next day, the sun came out again, so I moved it back in to the garage; did the same thing with the engine, revving it up a few times before shutting it. As you can imagine, I realized that I had flooded the car the following day. Tried the standard procedure of flooring the gas pedal; no effect. Anyway, I did a lot of research everywhere and tired many "easier" methods, like drying up the spark plugs and cranking without gas pump fuse, etc. Nothing seemed to work for over a week. In the end, what actually worked was me installing a new battery, so I could crank the crap out of it. Here's how I found out how it worked: I would crank it withe pedal depressed for about 10 secs each time; I would do that 3-4 times with some rest period in between of about 15 secs. Then I would crank it WITHOUT stepping on the gas. Each time I tried it, it would sound like it was going somewhere. But then it would die again. I repeated that mistake for about 5 rounds until I decided to do something different. I would crank it with a depressed pedal for 10 secs for 10 TIMES with rest periods in between. On the 11th try, I would crank it without stepping on gas. It sprang back to LIFE!!! I think the logic is that the first 10 times were simply clearing out the fuel in the chamber, and the 11th try is the one that can actually fire. During my search, I kept reading that you should just crank it a FEW times which I found rather vague. Anyway, I should mention that I'm a total novice when it comes to mechanics of cars, including my 8, so if I could do it, most of you shouldn't have a problem.

Thank You
Once again the RX8 forum provided EXCELLENT information...
For the first time, I flooded my engine Memorial day. I never thought it would happen, after owning the vehicle for 7 years with over 130K miles. Went to the movies which is basically right down the street from my friend's house and thought the car was fully warmed up...After returning them home and spending the night, the next morning car would not start. I PANICKED!!!
After a couple of days of reading threw gobs of RX8 blogs, I concluded that I must have flooded the engine. Followed the procedure outlined and I was able to get it started...THANK YOU
Brief history on my car:
2004 6-speed with 130K plus miles. Original engine and starter.
By the way, if you want my advice on a battery: Optima RED TOP. I bought the battery in 2006 and he is still going pretty strong...Will say the cranking did take a toll on the Red Top, but he succeeded!

Im having the flooding problem also yet the method is unfortunetly not working for me. Ive even tried the method of removing the fuel connector under the seat of the rear drivers side.
I was wondering. If the spark plugs are covered in oil would this stop the engine kicking in? As i thought maybe removing the spark plugs, starting the engine to try flush the fuel out there, clean the spark plugs then replacing them might make a difference?
Ive added a video of the engine trying to tick over in case it helps.

well while i was out of town, i asked a friend to watch my car for me. even though i warned not turn off the car while the engine is cold, they proceded to do so. they ended up doing the owners manual for an hour. so my spark plugs where drenched. you would think they shoud just gaven up. but oh well, problem is resolved.
now i havent flooded a car ever since i was 17 yrs old ( i am 33 now) back in okinawa. now i can tell you, it was the most crappiest day of my life. all my friends back home are huge nissan fanboys, and me the only person driving a FC . so i had to hear, you should of gotten a silvia or a 180sx during that time period 92-97. but i can tell you, once you flood your car, you seem to learn alot from that experience.
well today i decided to post my own DIY to deflood. in fact is so easy. i also used this time to clean out carbon build up with seafoam, but you can skip that process all together. but if you want to , NYCPS has a good DIY for that which you can find here. https://www.rx8club.com/series-i-do-yourself-forum-73/diy-mazda-zoom-power-engine-cleaner-engine-cleaning-seaform-142852/
step one- go to your fuse box take the cover off. flip the cover over and look for FUel Pump fuse which should be 20A ( i have a 04) . but i hear its also 22 which i dont have.
step 2. go to Air pump and disconnect it. (which you find the picture down below) it would be to the left of the Bright yellow oil cap .
step 3. now i put in a new set of spark plugs, becuase it was my time to tune up any ways. but if you want to a easy DIY for that you can find that here https://www.rx8club.com/series-i-do-yourself-forum-73/diy-spark-plug-change-31872/ . but you want to skip all that,
then i should continue. get anothe car (unless you hve a battery charger) so you can do a jump. reason is, there is going to be alot of cranks , which will eat up your battery (also reason why i disconnected the air pump, it tends to use more power). after your 2 cars are set up for jump. start car 2 and let it run while you do the crank process. we will move to step 4.
step 4. you will need to crank your car for 4-5 secs , then turn back off for about 6 seconds (to save your starter) . you repeat this process for 50 -60secs.
step 5, get out your car start doing jumpings jacks for a minute or so
step 6- REPEAT STEP 4
step 7. put back in your fuel pump fuse, and crank the car. it should start wanting to turn on. if the car turns on let it warm up to correct temp. in my case since i did seafoam, i had to press the gas a bit to save it from turning off.
If your car almost starts, but after a few cranks it feels like its not wanting to start. go back to step 4 and work your way down the steps, till your car starts. then reconnect your airpump
now i am not a mechanic, but i do tinker a bit, especially when i was growin up back home. but the reason why i decided to post my own thread is, the DIY that i seen, never really told you how long you should try to crank your car, or you need so and such tool or item for the process, that you may not have while out in about. so i can see a person feeling like they are beating a dead horse, if they dont see progress etc.
only item you really need is car 2 and jumper cables, and that is pretty much it.
now i am not saying my DIY works 100%, but its the process that i learned back when i was in okinawa japan.
any ways, i hope this thread helps you in the future.

Just wanted to double check because I don't see that you mentioned this. Also, Did you let the fuel leak out of the spark plug holes before installing these new spark plugs ?
Has anyone tried using this Mazda TSB with good results ? http://www.finishlineperformance.com...5-08-1883f.pdf

Never flooded my engine in the 6 years I've had it, but left it with a friend for a week and it got flooded. Since we had just moved, we had no tools, heck we didnt even have a place to live so I ended up just taking it to the shop.
Now that I'm in colder weather I'll have to remember the procedures here in case I'll need them!

quick question - how does cranking the engine remove the excess gas (after disconnecting the fuel pump that is) - there is nothing "burning it". Yes there is no fuel coming in - but what about the fuel already in there.
The original poster does not mention removing the spark plugs and cranking - which seems to be a safe thing to do than having gas in mist form spray out of the plug holes waiting to ignite.
Thanks

Here's a video on how to de-flood your flooded rx8

Go fast, do it again
Thanks for the DIY, I followed it step by step and got it to start with the engine starting/dying about 4 times before it started for good. Little thing I did while doing step 4 is pressing the throttle all the way.
THANK YOU!

Hey guys, I had flooded my engine around a month ago, and I attempted to deflood it with the removing of the fuel fuse proceudre. Almost got it but I had to stop because the neighbors were getting angry.
I haven't tried since because I never have another car to jump mine with while doing it, but I plan on going at it again soon.
BUT my main question was: does it matter how long you wait to deflood it? as long as it isnt too long right? it's only been a month so far. Does waiting for more than a week cause serious damage?

Finally happened to me.
Tried to start the car but the battery died, a lot of blue stuff on the terminal, enough to eat through the copper terminal itself :O
Replaced the battery and tried to start it, starter was working but the car wouldn't turn over. Realized I had flooded it, used the method in the first post (didn't change the sparkplugs). It worked, had to keep revs up to prevent it from dying again. Had seen a few videos but didn't have crazy amounts of smoke pouring out, it smelled tho.
Thanks for the DIY! saved me a trip to Mazda
Other details: I'm in So. Cal. weather was a pleasant 65* F, while flooding and de-flooding the car.

My 8 flooded a few days ago after sitting for a couple weeks. Took me about 20 mins to deflood.
I used the method that has worked 2 other times for me.
1 Don't remove any fuses at all, but hook up some jumper cables to a running car
2 Hold gas pedal all the way down
3 Turn engine over for 10s
4 Rest for 10s
5 Repeat steps 2-4 5 times
6 Try and start regularly (no gas pedal depressed)
7 If no start repeat steps 2-4 7 times
8 Try and start regularly (no gas pedal depressed)
9 If no start repeat steps 2-4 10 times
10 it should start by this time.
Each start attempt you should feel it almost start or possibly start and die....you're getting close. If by step 7 it doesn't even attempt to start, probably not gonna work for ya.
