My '87 RX-7 won't start

I have an '87 mazda rx-7. It hasn't restarted after I turned it off with out letting the engine warm up ( I know bad move!). I took out the spark plugs and let the chamber air out, thinking it was just flooded. When I replaced them, it still wouldn't start. When I put the key in the car, everything seems to be working fine, nothing out of the ordinary except when I turn the key the rotars spin. There is no jolt or feeling of the car wanting to start. I smell gas so I don't think that it is the fuel filter (which has been replaced recently, {and put on the right direction, I might add!}) Or fuel pump. This leads me to believe that it has something to do with the spark plugs or wires or ignition. The spark plugs seemed to be carboned up, and I'm pretty sure the wires are put on correctly. I'm just confused and I don't know where to start? Any suggstions would be greatly appreciated!- Thanks

Your gonna need to de-flood the enine. Which means taking the plugs out, disable the ignition ( I think that it is a green fuse 'injection' in the engine compartment), spin the engine over in 10-20 spurts. About 10 times (let the starter cool down ever few times), put NEW plugs in it, make sure the battery is really really charged up. Then start cranking it with the fuse still out and then have someone put the fuse in while you are cranking it (2-3 secs after you start cranking). This might help your problem.

Then do an oil change.

Also, adding some oil to the chambers before cranking it with the plugs out will help clean the fuel out and add a little more compression.

All this will help, but don't be surprised if you have to repeat it a few times to get it started. Ie it might try to start or start and stall because its so flooded.

Another issue is that you enigne compression might be getting low, so have a compression test done after you get it started and have driven it for a few days.
