Just a word of thanks to forum members - As a new RX-7 owner, I found myself with an unusual problem. Got gas, got spark, no start - almost as if a cutout switch was active.

Came to the forum, browsed a bit, and found out about a very peculiar habit of rotaries.

I had moved the car - just backed it up a foot. Next time in, it wouldn't start. I learned that short runs without letting it warm up will cause flooding upon the next start, and that there was a procedure called 'unflooding'. Also found a link to Rotary Performance Inc. that gave me the step-by-step.

Went out to the garage, ran through the procedure, three times, and the car is alive again!

Without the help of the forum, I'd still be trying to figure this out. Thanks to all, and special thanks to Rotary Performance for some good documentation.

 

You are doing it the hard way then
one of mine is stock with true dual exhaust and a cone filter and it floods unless I either turn it off and on in under about 30 mins or wait about 7-7.5 hours.
The easier way: Crank it, if it floods, unplug the fuel pump, crank it till it starts (or tries to) and then plug it back in. That's why so many people run fuel pump cutoff switches.
(optionally you could just remove the check valve in the pump and solve the problem altogether)

Oh yeah, welcome to the forum!

 

Ever since I got my injectors cleaned the car has flooded very rarely, even when I shut it down cold. Fuel cut switches are band-aids as many have pointed out.

 

Yeah well if you were as lazy as me you'd get one!
I only really need it on one car thow... I have one that floods about once a month and one that floods on the second monday of every week.

 

this works very well when it comes to unflooding. look under the dash ull see a relay thats black with yellow sides, i think its along the sterring shaft. disconnect it and hold it to where u can just push it back on easly. start ur car and let turn over till it sounds like its gonna start, push in the relay in give it gas and it should start. u might have to try it a few times, good luck.
