Hey guys so I'm brand new to the RX8 club but have been on here searching many times for various types of issues with my 8.

To Start Off:
I own a 05' 6 spd White RX8. already had my engine replaced under bad apex seals and failed to pass the compression test along with about 1200 counts of missfire in rotor 1. So mazda warrentied the engine and replaced it for a brand new one ( or so they say ). 700 miles after that im driving about 25 mph and everything electrical in the 8 stops and engine dies. Ipulled hood open and saw a mess of melted wires everywhere. Mazda told me this was due to a weak battery over powering my alternator and it caused that issue. kinda sounds like a hunka **** to me. got that fixed car has been runing great since.

Problems now:
I just Recently had gotten a flat tire and let my car sit for about 3 days went to start it just to make sure everything's going great. car started right up i let her run for about 10 minutes you know letting the rotary warm up and such. then went back inside. 3 days later, Went to go start her up and the engine turned over just fine, but no rpm gauge movement at all. tried to turn it over some more and still.. thought maybe the starter wasn't initiating the flywheel or something..

turned it over again and noticed white smoke out the exhaust smelled like gas. kinda got to looking at videos on you tube of flooded 8s. most of the videos i saw pretty much sounded like the exact problem I'm having. in the owners manual its states you know unplug the fuel pump fuse and turn over the engine for 8 seconds and leave it for 5 seconds.. repeat untill the engine sounds like it wants to start. put the fuel pump fuse back in and start her up to run out all the excess fuel... Tried this series of steps with a buddy who owns a 7 and about the third cycle in, i started loosing power seemed to be that the battery was getting low because of so many attempts.. so we put on some jumping cables connected to both batteries and let it sit for 5 minutes and tried again.. only this time to seem to loose even more power..

anyways i haven't been able to get it started since then, any tips ideas anything would be greatly appreciated guys!

Yes, it sounds flooded. Yes, if you go through many crank attempts it will drain the battery like crazy, ideally you should have it hooked to jumper cables from another car during the crank attempts to help mitigate this.

When you had the engine replaced, did they replace the coils, wires, and plugs? It sounds like one or more of those was failing as well, and is probably causing your flood now.

One thing to keep in mind that if your 8 is flooding because of a problem that you haven't fixed, you won't get it to start through a deflooding, because the problem still exists.

It's like turning on the hose to fill the kiddie pool, and then trying to keep the pool empty by bailing it out with a bucket. You aren't really getting anywhere.

Still the original starter? If you haven't gone over 100,000 miles yet, take your car to the dealer and get a new one ASAP. And RIWWP is right about there being something in the ignition system causing your flooding, check all of your coils for voltage from the starter, then check the end of the wires where they connect to the plugs. You will probably find something is weak which would be causing your flood problem. The starter could be causing it as well, the 04/05 came with a starter @ 1.8kw and Mazda put out a TSB for an upgraded starter @ 2.0kw that cranks higher RPM on startups. If your starter is original and is weakened from deflooding, you might not be getting enough spin to get proper compression for combustion.

FYI, he can only get a new starter from the dealer if he hands over the cash for it at the same time.

The free starter was only under the TSB, which is only free-of-charge while the vehicle is under the bumper-to-bumper warranty, which is 3 years 36,000 miles from date of first purchase. And since that TSB is only valid for 2004s and 2005s, the youngest 2005 would still be at least 2 years past warranty expiration. (Mine for example was purchased Sept 2006, making my B2B expire in Sept 2009 if I hadn't passed the mileage well before then)

I thought the starter fell under the same TSB as the engine and was covered for 8 years/100k. I could be wrong, I didn't research it much because I'm at 103k

No, the engine warranty is an extension of the original factory powertrain warranty, not a TSB. The warranty was only extended for the engine core and internal engine components, and does not cover anything else, including things that have to be replaced at the time of engine replacement.

I should restate TSB coverage though, as it only covers the repair free of charge if it involves something that still has an active warranty. The starter is not part of the powertrain warranty, engine core warranty, emissions warranty, or rust warranty, and thus falls under the only remaining "catch-all" warranty of the Bumper to Bumper.

Mazda was very sneaky with the faults of the early models...those bastards lol

I have no idea what generated that comment....

Easier way for him to tell on the whole starter, is to get the model number off of it and tell us what it is.
Anyway...........yeah, sounds like flooding due to ignition which you guys are all over, just thought I'd point out that he could check to see which starter he has.....even though it doesn't really sound like that.
Hey, RIWWP.....don't you have those model numbers in your Noob thread?

basically it's................

ENGINE STARTER INSPECTION / IDENTIFICATION
Some vehicles will require engine starter replacement depending on VIN / production range, and / or visual
identification. Use the inspection procedure below to determine if starter replacement is necessary.

AUTOMATIC TRANSMISSION VEHICLES:

1. Is the VIN at or below JM1FE17N* ** 148961?
No = Starter replacement is not necessary
Yes = Replace

2. Inspect vehicle’s starter label to determine starter type. Starter label can be seen under hood on driver’s
side.
- If label indicates “N3H2 A”, replace.
- If label indicates “N3H2 B”, “N3Z2” or later, do not replace starter.



MANUAL TRANSMISSION VEHICLES:

1. Is the VIN at or below JM1FE173*** ** 150745?
No = Starter replacement is not necessary.
Yes = Replace

2. Inspect vehicle’s starter label to determine starter type. Starter label can be seen with vehicle on hoist and
using a mirror.
- If label indicates “N3H1”, replace starter.
- If label indicates “N3H1 A”, “N3Z1” or later, do not replace starter.

Hey guys , i bought my RX8 about 2 weeks ago and for the first 3 days the car was running all good and smooth , problems started right after 3 days and it was not starting straight away while its warm. Because it was weekend i didint get a chance to take the car to the mechanic. On monday morning i jumped in the car i was on my way to local Mazda dealer and when the car hits 3000 rpm to about 4500 rpm it had a lag and a lack of power. When i got to Mazda they told me its the sprak plugs and the leads. Hooked up the car to the computer and it showed an o2 sensor issue, they cleared all the errors and the car was fine for about 10 minutes and the issue came back again. I got back to the dealer and they replaced my o2 sensor and spark plugs and all and the car was running exellent for about an hour and the same problem came back up. My spark plugs are fine i checked them and if i had any bad Apex seals the sparkies would be black or oily. It seems like the air and fuel mixture isnt right because the car is choking and backfiring. I'm thinking its my ECU playing up,sending bad amount of air or fuel. Anyone had any similar issues ?
Anyone else had a similar issue ?

There are a multitude of answers for your issues. What condition is your cat converter in ?Have you reset the ECU/PCM ? the list goes on......
