Thanks to all the 'no start' threads, I don't even worry when I can't get her started right away (which doesn't happen often anyway).

My engine has flooded a couple of times so far this winter, and it always starts after unhooking the 'blue blade connector' by the leading coil, turning the key with the gas pedal all the way in, re-hooking the blade connector, and bada-bing.

I just have a few questions about this, as I want to learn the 'why' as much as the 'how'....

-What exactly is this blue blade connector? (is it the fuel pump connector?)
-Why does this work?
-What would happen if i did this exact same procedure without unhooking the connector? I mean, by just flooring it while trying to start it.
-There's another blade connector by the trailing coil.... which one is that?
-Is this procedure applicable in a piston engine?

boy i feel so ignorant sometimes... surely appreciate the help.

I have that problem also.
3-4 times over the years, I have had to have the car towed in because it just will not turn over in cold weather.
It always ends up needing the simple procedure of "deflooding" done.
I have been told it it because of carbon buildup in engine, something peculiar to the rotary engine.
Apparantly a simple process to deflood engine.
Never has cost me more than 15 dollars or so to do that procedure.
Finally someone recommended changing sparkplugs, which was the reason for an earlier post here.
Let me know how you resolve this.

 

I'll let someone lots smarter than me explain 'why' the blue plug removal works, but it does cut off fuel supply.
Do yourself a favor and put a switch on it. I did, works great to un-flood when in the car, also a decent theft deterent.
If it floods by just sitting overnight, you've got leaky fuel injectors.
The 'accelerator to the floor' to cut off fuel option didn't appear on RX-7's until around 1989 or '90.

Good luck!

 

My -SE (#2 car) has the same issue. When I first got it, it would flood after only 5 min or so of being off. I drove it off the auction lot got gas and was stuck. I found that my injectors were leaking badly (front rotor especially). I pulled em out and back blew with compressed air and now they are sealed. I thought I had the prob licked but it still flooded(s), come to find out after removing the drivers side bin that a mouse had gotten inside (fuel pump wire grommet was loose) and chewed up some wires, well I’m sure the fuel pump one was in there. I put in a toggle switch on the fuel pump wires and haven’t had the prob since. One day I will clean them up but it is cold and rainy these winter days. I read that the 84's actually had a recall on this prob, the wires would chafe as they went into the bin. The blue spade sends the sig to the ecu that the motor is turning so it closes the circuit for the fuel pump. You must let the car warm up to operating temp as well, you can’t just move it and turn it off or it will flood. I guess the RX-8's have the same issue. Something to live with, the fuel cut switch has made a lot of folks happier, including me.
