Your probably flooded. I am unfamiliar with the FD but I can tell you the general solution.
You need to cut the fuel injected into the engine, spin the motor for a bit, and then turn on the fuel and start up.
On FC's you can pull the fuel injection fuse or disconnect the crank angle sensor.

Remove the fuel pump relay, crank for 10 seconds, wait 20 seconds (to give the starter a breather) and repeat. Then replace the relay, crank, add a little throttle foot action, the car should back to life. Let the car warm up so you don't re-flood the engine.
As a general rule, if you start the car cold, let it warm up to at least 40* C before shutting it off to help avoid flooding.
Good luck,
Josh

How to un-flood you FD
1 - Remove the EGI Main Relay (see below) to disable the fuel pump.
2 - Crank the engine for 10 seconds.
3 - Wait 20 seconds for your starter to rest.
4 - Repeat 2 and 3.
5 - Put the EGI Main Relay back in the fuse box.
6 - Crank the engine.
7 - As the engine tries to start, give it a throttle to help it start.
In the future, if you have to start the car, let it warm up before you shut it off.
You can also inject some ATF or heavy motor oil directly into the spark plug holes to help build compression, but this might not be necessary.
Hope this helps.

It sounds like you might need to put some ATF or motor oil directly into the spark plug holes to help build compression, and this is an opportunity to put in fresh plugs. (If you don't have a syringe, you can use the cylinder of an ordinary ballpoint pen.) During Step 6, if the car starts to stumble, like it's trying to start, tap the throttle a few times to help give it a little gas, and keep cranking. It might take 10-15 seconds of cranking during step 6, but un-flooding the engine just takes a little persistence, and I've outlined the steps for you.

To add a couple things on deflooding, hold the accellerator pedal to the floor, This will draw more air through the engine to remove the fuel. Pull the plugs and clean them. I have a beadblaster that works great for cleaning plugs. Shoot them with brake cleaner, blast them, shoot with brake cleaner a 2nd time and blow dry with compressed air.
You don't really have to clean all 4 plugs, just the lower ones in each rotor.

well i got the car started, i had to tow it and bump start it and it kicked in, i went to get it serviced and got a compression test done and i have low compression (lowest was 4.9) what causes low compression? is it the seals on the rotor going? also how would it affect the driving. one last thing, how easy is it to rebuild the engine?
