I have had my 2009 RX8 for almost two years now. Last year when it got cold, it flooded out and would not start again. I spent $75.00 on plugs and after jumping it finally started slowly and then blew a bunch of smoke and came out of it. Again this year I went to start it when it got bitterly cold and it flooded again. I changed the plugs and put in a new battery and this time it will not start, it just sits and cranks and cranks. I can smell that it is getting gas. I know I am getting tired of changing the plugs (laying out in the street in 25 degree weather. Does anyone have any advice?

You keep replacing the plugs, but have you paid any attention to the rest of the ignition system? The plugs need sufficient coil performance to send them a charge, as well as conductive wires to get the charge to them. Coils and wires fail over time too, and I'm guessing you have been ignoring those?

How cold is bitterly cold? Mine has to get up regularly in -10F weather and doesn't have any problems, though I do have a heating pad on the oil pan that I use regularly.
Consider changing the coils and wires if you haven't already.

What deflood procedure are you using? It should not be getting gas if it is already flooded, that would be counterproductive.

kevinande

If you continue to turn the key and crank without Holding the throttle to the floor, pull the fuel pump fuse, or disconnect the ESS, it will continue to dump fuel into the engine. The car has no idea it's already flooded and just stops delivering fuel.

RotoryVirgin

^ that's what I was getting at. He may know what he's doing, may not. I was trying an open ended question to have him answer with what procedure he's using, or think to himself "wtf is he talking about?" and go look up the procedures on his own.

kevinande

I did not see you logic at first, but after a quick re-read, I see where you were going.

Coryell

The other day I did remove the fuel pump fuseand cranked for a while, but still to no avail. Everytime I try I also hold it to the floor, but still nothing. I will try again sometime this weekend. I have been wondering about the coils. How often do they need replaced? Is this common? The car only has 50000 miles.

kevinande

Typically the coils fail some where between 20 and 30 thousand miles. As pointed out earlier, if you don't know how many miles are on the coils, change them as well as the leads and the plugs.

Series2 RX-8s (2009-2011) are supposed to have the latest coil revision from the factory that lasts longer than the original coils, however there has been little proof to back this up and the recommendation stays at about 30,000 miles average till coils can start suffering bad. Average ... some last longer, some do not. If it helps sway you any more, A couple years ago an RX-8 with 30,000 miles on it's coils, plugs, and wires was dynoed, then brand new ignition was put on and it was re-dynoed the same day. It re-gained 28whp.

I really recommend replacing your coils and wires before you keep trying to deflood.

No proof that the revision is actually superior although time will tell. N3H1-18-100C only came about in 2012 though, the last year of the RX-8 which is why people refer to them sometimes as the coils for RX-8 Spirit R.

Agreeing with you and everyone else. The OP needs to do that and hopefully has not already damaged the catalyst or the starter. I wish we knew what country, city, State as well.

If you are asking my location it is in Southern Indiana. I will just go ahead and replace the coils and such before anything else. Any recommendation on aftermarket parts?

With a 2009, I highly recommend ordering them from Mazmart, who posted right above you ~$250 for a set of 4 coils. The alternative would be a BHR ignition upgrade for $500, another forum vendor.

Avoid ebay at all costs (counterfeits mostly), and I don't feel comfortable recommending older coil revisions (from auto parts stores) on the Series2 RX-8.

Southern IN, my guess is the Evansville area.

I would listen to them. I have heard nothing but good things about the BHR kit.

FWIW I have been using OEM replacements from advance auto parts for a while now (i'll have to validate mileage, dont want to guess) without any issue. Based on their design vs the mazda Brevs ... they are very similar looking, almost exact. YMMV

RIWWP

Yeah, I believe the BWD coils are the original supplier for Mazda's original coil revision, just selling the line to the public now. My concern would be more for the ECU interaction with the coils. I know there would be problems in JDM RX-8s, and I just don't have enough S2 knowledge to be able to talk about interactions there with any confidence. So I'd rather refrain from making a statement about what works and what doesn't.

Not that far south

Ok, so I have replaced the plugs, coils, etc. ( and three of the coils were burnt). It is still not starting. I had to wait until it warmed a little, as it was I was outside replacing them in 35 degree weather. Anyway, any other suggestions?????????????? I am about to blow this thing up

Have you done a proper deflood?

Can you pull start it?

Are you getting spark?

Are you getting fuel?

Coryell

I know that I am getting fuel. How do you say is the proper way to de flood? It got to cold to see if I was getting spark.

I have taken the fuel pump fuse out and let it crank for awhile. and when I go to start it I hold the pedal to the floor.
It did almost sound like it was going to hit once when I first tried to start and then it just kept cranking.

I always recommend that people deflood with ONLY ONE method at a time. Otherwise there are situations like this.

Pulling the fuse is doing the same thing as holding the gas pedal to the floor. BOTH methods cut fuel while cranking.

Either cut fuel with the pedal to the floor, or cut fuel with pulling the fuse. Don't bother doing both. When you go to restart, restart normally, foot off the pedal.

Repeat the no-fuel cranking 10 times, 5 seconds each, waiting 5-10 seconds between each. Then try starting normally. If it doesn't catch but seems to want to, repeat another set of 10. It may not start just yet, but it should be closer to starting. Repeat another set of 10. If it still doesn't start, then you will want to start looking at another starting option.

Make sure your battery can hold up to this, I recommend hooking up jumper cables to another car while you are cranking. You don't want it re-flooding due to a low battery

Coryell

Thanks I will try this this weekend and let you know.

Coryell

Well I could not wait until the weekend, especially when it hit 48 degrees here today. After 4 x's doing the de-flood procedure I again have a running RX8. Thank you for all of the help and patience.
