Short drive flooding and solutions ??????

Short drive flooding and solutions ??????
I've read through most of the sticky thread and am all to familiar with this scenario from my 13b 2nd gen. The fix in that car was to wire an interrupt switch for power supply to the fuel pump. Any time you were going to shut engine off you did so by cutting power to the fuel pump and waiting for the car to stop running. Then you would shut of the ignition. It allowed excess pressure to be relieved in the fuel system and prevented fuel from seeping out the injectors and saturating the plugs.
As luck would have it, my dad's car, the same RX8 with the SSV condition that I plan to work on this weekend, has flooded and he can't get it started. It took place right after shuffling the cars in and out of the garage. He's driving a rental for the time being, but when I get the Saturday I'd like to get the thing running for him again.
Swapping plugs and ATF or starter fluid (can't remember which) in the plug holes still work on these newer motors like it did on the 13b's? I seem to remember that helped evaporate the excess fuel in the chamber and the new plugs ensured there was no fouling. I think I need to pick up a Haynes manual or equivalent and some plugs for this thing. He's ready to sell as soon as he can get all the issues cleared up.

just try the mazda reccomended deflood procedure. press and hold the gas all the way to the floor, then turn the ignition on and crank for about 10-15 seconds. that helps clear the chamber of excess fuel.

WOW! I had previously read through the first 7 or so pages of the "flooded" sticky thread and I thought that was all. I just went back to re-browse and it's quite a bit longer than that.
I did find a link to the .pdf for correct procedures to get the car started again. I'll try those this weekend. Thanks for the help.
BTW, considering that this problem and the SSV (known by a different name on the 13b motors from 2nd rex cars) were well documented concerns from 20 years ago, how has Mazda R&D not been able to engineer a way to prevent this sort of stuff from happening? I suppose if it happens to few enough people that it won't totally kill their reputation, they may not deem it profitable to spend the $ in R&D to create a solution. Just a PITA and has my dad selling his car without hesitation.

Just a follow up to this thread....
I went to Dad's this weekend and tried a few things with the car. Mazda de-flood procedure didn't work. Tried it several times. Killed the battery and replaced it with a new one. Still didn't work. Put a booster on the battery. Still didn't work. Went to change the plugs and encountered more than I wanted to get into without a shop manual. Gray plastic covers that the plug boots seat onto. Started to loosen one to access plugs (assuming they were underneath) and thought I was losing the captive bolt assembly from beneath so stopped. PITA to access that area too. Looks like the shop may get his $300 anyway. That's the going rate local to him for the dealer to get a renesis un-flooded. Unrelated to this but mentioned in another thread, we were unable to tackle his SSV issue because we couldn't get the car started, so that's still looming large and the dealer quote was $3600. Nice freakin' car.
Sorry to vent but it really shouldn't be this hard.

Finally some good news. After trying for 5 straight days my Dad finally got his 8 "unflooded". It took a new battery, a trickle charger and about 2 dozen attempts before he got it to catch and run. As all have mentioned, smoke show was spectacular. Now that it's running again he'll try and get the SSV unstuck and hopefully get the CEL to go away. Thanks for the advice thus far.

...Well I have now, and it's P!55ing me off! Three times I've had the RAC out and this time he couldn't get it started. Garage isn't open till tuesday, so I can't even get it towed there till then.
I wish I lived on a hill! I don't think my wife is up to giving me a push. Could you elaborate on those "easy ways", please Max?
Toenail: Could you provide the link to that PDF please? I'll have a dig for it, but in case I can't find it.
