Have you actually tried to complete an unflooding procedure yet? Pulling the plugs out and letting it sit isn't going to do much to get rid of the excess gas.

Well for One thing you are In Edmonton!..and If I Know Edmonton,It is Freakin Cold!..so you may have a Frozen Gas line...as far as Deflooding,Try this.Take the plugs out and Clean them.Take the EGI FUSE out.(engine bay Fuse block),Roll the Engine over 30 seconds.NOW,get a Milkshake Straw.Dip it in oil,until almost full and empty the Straw's Contents into the Plug holes.roll over engine One Rotation.Now put the Plugs back in and Put the fuse back in,and Try to start it.DO NOT touch the Gas...you may have to do this more than once,and If the car WAS flooded.It should Start.Pleas make sure that the battery is fully charged too.....MATTYL..the engine will sound like it Has no Compression If the Engine is flooded.It makes a Whiney/Spinny sound ,no Chug/chug Sound..(sorry that is the best I can describe it!)..and 90psi is getting into Rebuild time,but lots of guys have Run on less compression than 90psi per rotor.
k dont laugh at me for askin these questions but i do not know alot about rotarys.... it does sound like how u described it but will the engine still start if the compression is really low? i havent dont a compression test on it but i will be doing one sometime this weekend, i tryed all the de-flooding stuff like pullin the egi fuse and putting oil into where the spark plugs are and all that and it still wont start..... maybe just leave it for a few days would that de-flood it or something?

Cold temp effect on compression affects any engine, but tends to rear its ugly head on rotaries that may be affected by carbon build-up & wear, weak starter, weak battery, fuel & spark issues. If you've ruled out any fuel and spark issues per previous recommendations, a quick way is to bump start it if your car is manual. Get a buddy with a tow rope/chain to drag you 10-20 km/h while you have the car in second gear with the clutch pedal depressed. When you reach a reasonable speed, pop the pedal. It will moan and groan but should start if everything is OK. If the engine starts after a series of pops and eventually runs fine, bring it to operating temperature and shut if off. If you realize that it's only running on one rotor, shut if off 'cause it's time for a rebuilt engine. If it runs fine, it should start easily on its own immediately afterward. Even if you have a broken apex seal, you'll be able to run it on one rotor but you'll know right away. If the car still won't start easily once warm, you may have further issues to diagnose. I hope your car is manual and you can try this. My experience with these cars goes back to the 80's and I remember many frustrating winter days with all my RX7s. On some of them, the tow rope was neatly tucked away by the spare.

There are only 3 elements to getting your car started. Fuel/Air, Compression and Spark.
Since you have a 2nd gen, I wouldn't have a clue how to troubleshoot FI, so I can't help you there, however you seem to have *too much* fuel, which is easier to solve than too little. When these things get flooded they can *really* get flooded. Take out all four plugs. Dry them off with a lighter then wire brush the heck out of them until they shine. Blow them off with compressed air if you have some. Crank the engine with the plugs out for a good 10 seconds (after disabling your fuel supply to the engine somehow.. dunno how it's done on FI but I'd assume there's a way to kill the fuel pump or stop the injectors from spraying or something). That should get most of it out. Then put your plugs back in and hook 'em up, and give fuel supply back.
So that solves the too much fuel and the not enough spark. The last is compression. Now you don't need to have stellar compression to start a car, but the faster your crank speed, the better the compression you have will be. Hook a running car with a good, solid, clean set of jumper cables to your 7 and crank away.
My car tested this spring with a "whopping" 7.2kg/cm2 compression. Not stellar in the least. In fact, boarderline. But it starts no problemo every time (knock on wood). It's got brand new battery cables, battery and starter, so it cranks at 300rpm, and a good dizzy cap, rotor, plugwires and plugs. I always keep a wirebrush and a lighter with me in case I need to deflood
