My 1st experience with unflooding my 3rd Gen was solved with a couple of phone calls. I would like to thank RotorSport Racing, Rotary Performance, and Pettit Racing for their assistance over the phone. I left the car with a body shop to get the bumper painted. They started the car pulled it to the rear of the shop and cut it off without allowing it to warm up. The next day they tried to start it by using the gas pedal. I went to the shop yesterday and of course it wouldn’t start and all you smelled was gas out of the pipe. The procedure on rx7.com for the 2nd Gen tells you to pull the EGI fuse and try to start. There is no posted procedure for the 3rd Gen, but it’s pretty much the same. I pulled the fuse tried to start holding the gas and clutch down for 15 seconds, then put fuse back in and tried to start normally. Repeated this procedure five times before calling Rotary Performance and was told to just hold the gas to the floor on the 3rd Gen and pulling the fuse wasn’t necessary. Turned it over with the pedal to the floor and she started with tons of smoke and a little from under the hood. If that wouldn’t have worked I was told to pull the plugs and turn over. I talked to Pettit and was informed that pulling the plugs and trying to start would destroy the ignition pack. Now, I’m confused about what should be done if the simple procedure doesn’t work. Should they be pulled and then try to clear the engine or just pulled, cleaned, and reinstalled without trying to start? Everyone should know this information because I have had my car for almost four years and never had this problem until yesterday and this is the second 3rd Gen that I have owned and sooner or later some shop or friend is going to do it to you, so lets find out the RIGHT way to unflood the 3rd Gen and I know between all the Rotor Heads on this forum we can come up with the RIGHT procedure.

ALWAYS try the simple method first - and bear with it. If you do a search, you will find advice about pulling the fuse and/or the plugs - no doubt it's good advice - but definitely (IMO) should be used as a last resort only. I've had about three or four times where I've needed to unflood - and all have been solved by the basic method. The worst was actually last week - and I was certainly contemplating the advanced methods - but after about 10 minutes of trying - bingo!

WOT + turn the key for 15 seconds
no throttle + turn the key for 15 seconds
repeat until she kicks over (and resist the temptation to pump the pedal when it starts to chugg into life).

I can't remember who posted this info first - but whoever it was - you are a champion.

well i dont know if i would crank the engine for 15 seconds sounds a bit excessive to me, i wouldnt wanna fry the starter motor. i dont know if it would but i like to be safe. when my car was flooded and wouldnt start after many trys my mechanic told me to put all the plugs out and spray them with brake cleaner and light them on fire with a torch to clean all the gas and oil off of them. this trick worked wornderfully for me my car started the first try. Wouldnt WOT + turning the key for 15 seconds flood the engine even worse?

No, it won't flood the engine as the fuel is actually cut off during this procedure, it is part of the logic of the ECU evidently.
I posted this same technique years ago, though I recommend only cranking for 5 - 10 seconds at a time. Using this technique I have never, repeat NEVER not got my FD's engine unflooded. (Though I have had to hook up two batteries on occasion! )

Well, it's not.....

You can cycle the starter for 2-3 minutes without damaging it. The key is to let it cool down between attempts (30 minutes to an hour).


So would putting in a new set of plugs. Are you old enough to be playing with fire?

Did you miss that part about the ECU switching "OFF" the injectors during start if the throttle is to the floor????
