Just thought I’d drop an update. The shop has been swamped so I haven’t been able to compression test it, but today was warmer then usual and my car was acting differently. Today the car started basically on the first crank, and when I went home (the car was still hot) it fired back up on the first crank. This was a welcomed surprise but I’m even more confused now. It did FAIL to start yesterday when I stalled it backing into my lane way. I also had a few issues today but as soon as I put the car into unflood mode and let it crank for a second, the second I took my foot off the gas it fired right up. I’m starting to think this could be a fuel related problem. Anyone any ideas??

Well if you are not having plumes of white smoke or blue smoke, but you still have flooding issues I suppose yeah it could be fuel flooding. I'd still check compression, but there is two ways you are flooding with fuel. Either the injectors are draining into the chambers when the engine is shut off/priming.......Or your ignition system is failing to start a low compression engine and at a certain point excess unburnt fuel coats the sparkplugs.

Now I dealt with a flooding motor(coolant) for the most of my 4 years at college. For me when you go to start can you tell that the motor is spinning slower or sluggish due to having to push fluid out of the chambers? Sometimes my engine would do fine, then sometimes it would be completely flooded, I attributed this to however the rotors happened to stop in their cycle when the engine was turned off.

i actually had this problem a year ago in my rx7 so I know it isn’t that. The car doesn’t have any coolant smoke on startup and it fires up on both rotors. My rx7 would start but would only run on one rotor until the coolant was pushed out of the second housing. I drove it like that for a couple months, fun times. The rx8 also doesn’t overheat at all and my coolant is still a green color lol.

Alright, thank you for everyone who’s replied on my thread.. but I’ve done a compression test... and the results are, 60psi on front rotor and 30psi in the rear. Guess it’s time for a rebuild after all. The car started missing like crazy yesterday and will barely run now. Sounds like she’s only running on one rotor. The strange part is the rear rotor has consistent 30-31 psi jumps and yet the car just died one morning. I went out to start it and it said no. So while the compression wore evenly it just quit all at once. Thanks again guys, I’ll be sure to pull this thing apart and get her going again

Completely toast. There is an easier way to go about it and just get a new engine. Doing a rebuild can be more expensive and far more time consuming depending what you need.

If you feel comfortable with an rx7 dont let these guys put you down and go for it! Basically everything you could need is here on the forums for REFERENCE

But dont say they didnt warn you against doing it yourself
