Hi, my names Jacob from pa and I'm a New guy to this Forum and to a mazda RX8 6 speed all black, looks beautiful. Owned a Speed protege. I got an RX8 that was run out of gas and flooded due to not cycling the Key on and off. Am I able to post my problems about it here or should I wait till I can go to a technical section? Thanks.
second, you can post it here some of us will help.
third, did you have a compression check before buying? more info on the car will be required for any of us to start guessing at any sort of problem that may or maynot be present
forth, what part of PA?
fifth, how can you be flooded and out of gas? any who deflooding is easy and talked about in the thread I mentioned (if your lazy, hold gas pedel to floor crank car for 5 secs wait 15 secs, then try and start(rinse and repeat) if that dosnt work try compresion starting it but pulling it or down a slight hill( not super good to do but will work))
Ok, so here goes
I'm from northern PA. Hour south of Erie
So the kid I got it from Ran it out of gas. When he put gas In it he didn't cycle the key to get gas to the motor. He said he got a compression test done an it was ok. He changed the started as well. So when I got it, I drained the oil, put fresh in and new oil filter. Changed the plugs wires and coils all at the same time. I went through the deflooding process several times with the gas peddle to the floor. As I was lifting my foot up it wouldn't attempt to roll over to start and would only back fire, like a gun shot. So I'd keep trying to deflood it. It also has a grumbling sound coming through exhaust but That didn't work, so I tried pop starting it in 2nd but would not stay running at all and I did not have throttle at all, it would only pop and backfire.
Thanks for the time and help everyone
Did you also change spark plugs? Check to see if they work properly.
VISUALLY inspect inside your cat converter.
Clean eccentric shaft position sensor, followed by 20 brake stomp procedure.
READ the thread sonic posted a few times. All of the info is in there. If you can't find it, check the areas I posted using the Google search feature. There is literally TONS of info that can help you out.

okay doesn't mean passing, did he give you any numbers for it?

Are you 100% positive you didn't swap any of the wires when you changes out the ignition components?
does the car still have a catalytic converter? you might want to look and see if its still intact.
are you 100% positive it even getting fuel? if the car was ran dry there is a chance the fuel pump may have gone bad.
Like I said before please read the new owners thread all of this info and whole heck alot more is in there
So on the body there is 130xxx miles. Motor is Roughly 40xxx miles I was told. It's an 04 6 speed. I changed plugs and I triple checked the wires. I will be checking to see if there is spark and will be checking the fuel pump to see if its working properly. The kid I got it from told me the compression reading was a 7.4.. And I know there is more then 1 reading... I'm just going by his word that the compression is fine. He had it checked a month ago. It also does have the Cat still and have not checked that.
When your pedal is to the floor while starting, you're not getting fuel, so you need to do about 5 seconds of that, then stop, then a regular start. So in no situation are you lifting your foot up while cranking, and little things like this matter. However, when you put new plugs, that should have solved the flood condition anyway. So I don't think flooding is your root problem.
Have you seen this car run at all? What was the condition of the old plugs when you pulled them? Any gas? Coolant?
I also don't fully understand the point about the kid not having cycled the key. He might have had a rough firsr start, but with a working fuel pump that should have cleared itself up. That's a sketchy reason for selling a car :/
Ok. The reason why I had lifted my foot is because that's what I had seen on vids to do after about 6-8 times of the deflooding process but I'll steer from that. When I pulled the plugs they were wet and smelled of gas. The reason the kid got rid of it is because he doesnts have patience and gave up on it the day he ran it out of gas. I appreciate all the help as well. Also, he said afterput gas in it and tried until the battery died. Then hooked it a jump pack and kept trying. I'm getting the feeling the fuel pump may have burned up?

Possible but unlikely, meaning your fuel pump is not likely to have burned up from this singular incident, but maybe was already failed? Maybe the fuel pump was the issue all along? When they stop working they tend not to pump fuel anymore thus acting like they're out of fuel.
Funny he got aggravated enough with his car for running out of fuel that he sold it? :
I understand. I'll look into the fuel pump. But that's how he is he says, once a car breaks down on him and gets rid of it and gets another one. He doesn't put effort towards them. He mentioned that he had it running for a minute then it quite, so he tried it again and it struggled but then the battery died

The wet plugs and backfires make me feel like fuel is still being delivered. There is a thing that can happen when the car is low on gas that would fit the symptoms, but it's not a fun thing. Check the fuel pump first for sure.
Under about 1/4 tank, in a hard left turn, the fuel sloshes away from the fuel pickup, putting air into the fuel line which creates a lean spike when it gets to the engine. If the car is at full throttle at that moment, you risk a severe detonation which can take out apex seals. Which means new engine time. To the driver it may feel like the car just ran out of gas, and it's unlikely it will start again, and the exhaust will sound weird. A comp test would tell you for sure, but it would have to be pretty severe failure to exhibit your symptoms, so even a regular comp tester for piston engines should show it and maybe save you the cost of a comp test. If the fuel pump investigation yields nothing, that might be a good next step.

Ok, thanks I'll look into it and go from there. He wasn't driving it at the time. It was either extremely low on Fuel or something went bad.
Yes I agree like I said but Loki articulated it better, it's unlikely to be the fuel pump for all of the reasons he mentioned and an air embolism is possible, but now you say he wasn't driving it? That's a bit confusing as well. But my point about him selling the car was that the car doesn't fuel itself, it has to have a caring and attentive human owner to do so so him taking out his oversight on the car by selling it is rather comical but not in a good sense, as after all it's not a break down, is this guy the kid with affluenza by any chance?
Hope you got a great deal on it and get it running for the sake of making a point, though it sounds like it'll probably be lost on him anyway.
What I got from it all was it was sitting in his driveway and he started it up and after a minute it died on him and it struggled to start again but it didn't. Sorry for the confusion.
I've had mine well over 3 years and only flooded it once shortly after I bought it due to a bad coil and plug.
Took me about a I/2 hour to deflood it.
Ok, I'm still doing research on what's going on with mine. I was told mine may just be really flooded because it's gurgling through the exhaust. So it getting Fuel, spark, was told it had good compression and obviously it's getting air. I read that it could take 20 minutes for some but I've also read it took somebody 2 days to deflood there's.

There is a DIY for deflooding.
Follow one method, don't keep trying different things.
Mine took about a half hour because I was waiting a while between cranks so as not to fry my starter.
I have a charger with boost mode on it.
I hooked that up to my battery after ensuring that the terminals and posts were clean, and I had a full charge on my battery.
If you don't have a charger, hook up jumper cables to another car or spare battery.
I chose to pull the fuel pump fuse.
I can't remember how many times I turned it over.
I probably cranked it for 10-15 seconds, maybe 6-8 times?
It was 3 years ago, so I'm not sure.
I let the starter cool off for a few minutes between cranks.
Put the fuse back in and it fired right up.
He mentioned that he had it running for a minute then it quite, so he tried it again and it struggled but then the battery died
If the battery died, take it out and bring it somewhere to get it checked before all else.
If the battery is bad or weak, you're chasing your tail trying to deflood it.

Thanks for all the advice dude. I'm thinking of just replacing the battery. It's alil over a year old, but it's been cold here now and it's killing it pretty quick.
Still dealing with this only because I haven't had time to do much. So I de-flooded the car awhile back, left the plugs out to help dry it out in there and only cranks but no start. Cleaned the E-shaft too. Will be getting a new battery but when I got this car, it sat flooded for like 2-3 weeks and plugs were soaked. Being that it sat that long, the motors more then likely ruined right?

If it's ruined, it's not because it sat. Sitting with gasoline in the chamber is fine. Sitting with water in the chamber is worse, but from what you're describing that's not your case... right? right?
While you were trying to deflood it, did the behavior change at all? Did it try to fire?
You might try entirely new plugs, depending on the condition of the ones in there now. By the way, can you take a picture of them? Can learn a lot from what's on the plug.
You said you were going to check for spark... did you?

. Time and abuse kill batteries not normal outdoor temperatures (but actual high bonnet temperatures do if added up over a long time period like idling constantly in downtown Phoenix for your courier job). A battery will lose ~1% of its charge every day if there is ZERO load attached - it is a chemical reaction that cannot be stopped with Pb-acid technology. And as it sits and is below 100% state of charge, sulfation begins. Deep draining of batteries effectively greatly lessens the life of the battery - think marine use without charging.
Ni-Cd is better but there is still a loss. In 90 days, you've lost about 90% of the CCA charge capacity. You must recharge the battery to do normal tasks like starting those awesome dual doritos in the cold.
