Help, Help, need help.
How many if you have had issues in warm weather flooding. Where your car sits for a few days and when you go to start it it's flooded.

I usually operate my car at least once a day but on occasions I have not used my car for 2-3 days only to find that when I try to start it it's flooded and the weather is warm.


Have any of you had any information in relation to this (Tech Bulletins or solutions)? Have any of you had this problem, mine has occured in temperatures between 55 and 80 degrees.

Not in my RX-8....

In my older piston powered car, (at least one of) the fuel injectors would dribble from residual fuel pressure, causing hard starting. A while after replacing injectors, it would happen again. The root cause of this was probably engine compartment heat coupled with poor design of the fuel system / Bosh injectors.

The remedy was new injectors and wrapping the fuel lines/rails in header wrap.

Mine did this once after I left it sit for about 2-3 weeks; I never did figure out why, and it has not done this since in hot or cold. The only solution the dealer gave me was to keep cranking it with the gas pedal down.

Do you make sure the engine sits at idle for a few seconds before shutting it off? You can flood it easier if you do not do this.

are you sure the car is warmed up completely the last time you shut it off? Is it flooded and will not start or just takes a long time to start/multiple cranks mabye like 5 seconds or so?

can't even get 2 cranks before a total shut down.
turn the key, nothing, not even a peep.
jumping the battery does nothing.

Mazda already replaced the battery and starter.

My guess is that there is so much gas in the engine that the starter
won't crank against the pressure, or some other electrical circuit shuts everyting down.
No way to get the 7 seconds that Mazda says to perform if flooded.
Push starting is a no go either.
and the temerature out side is 65 degrees or hotter.

Yes I got the Battery and starter too. If I don't start the car for two or three weeks then it sure cranks slow. The cars security system and other things are always draining the small battery. Have you ever checked the water in the battery or the connection of the posts. They say no maintenance on them but they still boil out from the heat. Charge your battery good and attach your jumpers to a running car then try to start it.

There is no way your engine is getting "hydro locked" and not turning

There is a problem with your starting system...either the starter/solenoid, wiring....or the ignition key, module or something, or the battery and grounding


I would try and jump direct to the starter to see if it works for longer than that...and then check out the rest of the system if it works

Well all that mazda has ever said is flooded, when the car is towed in to the dealer.

Now in cold weather 'flooded', I can buy that.
In warm weather, not so fast.

Even when jumped (and I presume flooded as mazda claims), the
started does not engage or turn over.
I thing there is more than one issue, but try telling that to Mazda.
Thanks for all the posible solutions, There good ideas.
And I'm fresh out of ideas.

I work from home so I could go a week without starting my RX-8. I live in Northern CA and even in hot weather 100+ I've not had that problem...

Have you asked Mazda about it?

Sounds like you need a new mechanic to look at it....obviously they are missing something.....

sandia8

the battery jump is a no go, I jumped it once (3rd time this occured), and a tow truck jumped on the second ('fllooded' occurance)

sandia8

the '8' makes me long for my 7.
It NEVER failed to start, hot or f'ing cold. (colorado cold)

As long as I never let the choke dis-engage until the engine was warm.
