When flooded can you not just pull the fuel pump fuse and crank the engine over a bit to clear the fuel before replacing the fuse?
You can, and this is what you used to have to do before Mazda implemented the 'foot to the floor when starting turns the engine over with no fuel pump' on them. Can you imagine telling the wife if it doesn't start dear just pull this fuse thing out of here...
Put the accelerator to the floor has a far better chance of success.

You can,fuse number 22. Also holding the accelerator down and turning over for 10 secs shuts off the fuel pump too. But if it really flooded turning over might not suffice, a plug clean/dry is needed.

If it's badly flooded, and holding down the accelerator doesn't work, you will need to remove the fuse and keep turning it over in short bursts until the excess fuel is removed (if you just sit there churning away, you'll overheat the starter). This will probably flatten your battery before the car starts, the Mazda Assist mechanic will do it with jump leads and his engine running. When mine flooded, it took about 45 minutes of this to get it started; churn a few times with no fuel, put the fuse back in, try starting, take the fuse out, churn a few more times, put it back in, etc.

The cold engine shutdown procedure is to hold the engine at 4000rpm for ten seconds and then turn it off without first letting the revs fall. Better to let the car warm up.

If your rotary floods alot, it might be a little low on compression.

2 years old, 65K (lots of fuel) and no flooding problems whatsoever. I'm always the numpty who starts it on a winters morning and then realises I need my phone charger out of the locked glove box. Always starts again no probs. I knew someone who sold his on for the fear of flooding!!!!!!! Keeping mine til it hits 100k and then wondering what I can replace it with that puts a smile on my face on the twisties for the money. Hoping Mazda might release an RX9 otherwise I'll have to go and look at the new Nissan 370z but that only has 2 seats and will be more ££££££.

From my limited experience of a) using one for a few weeks, and b) Shuffling the round a car sales pitch flooding only occurs after repeated short starts and stops, with a good battery and not running the tank right down you should encounter no problems with the normal usage
nt to one last night best way take out the fuel pump fuse and crank for 25 sec then replace if no start repeat ,hope this helps all .ron

My RX-7 and RX-8 are ok.. The 7 I will let idle for several minutes if it is a short trip.

With the 8, I have the 'R3' version, which actually has a series of lights under the odometer so you know when it is safe to turn the engine off again.

On a hot day, its only a minute or two before the engine is ready to switch off. I've yet to see in winter though.

As the fella above said:

"theres a very simple way of getting around it by holding the revs at about 7k for 10 secs and turning the engine off and letting it spin out..."

Doesn't need to be 7k, about 4k revs count to ten, turn engine off as you floor the pedal and hold it down for a few seconds.

PH forum software is quite possibly the worse forum software I've ever come across. I don't understand why they don't just use something decent. There's plenty available.

if you search on youtube there is a video showing the correct warm up and shut down procedure
