stuck injector???

hey i need help fixing my car, i went out to start it today and it just spit and sputtered without firing, so i did the normal pull egi fuse, crank, replace fuse and try again, i didn't put atf for compression because i was on my way to work and couldn't afford to stop and do a oil change in between. i pulled the plugs and they were soaking wet and reaked of fuel, so i cleaned and dried them off and put them back in and the car fired ran for ten seconds then died. so i pulled the plugs again and the top plug against the fire wall was soaked again but the one under it was relatively dry, and the front rotor was ..... kinda wet. is this a sign of a stuck/leaky injector? i pulled the plugs and check for spark and all were fireing,

also when i crank the motor over for 4-5 seconds my cooling system is already pressurised and without the cap my buddy said it bubbled. but we pressurised the cooling system after the bubbles and didn't experience any pressure loss? i'm new to rotory engines but it has failed to start and i wasn't able to make it to work and my boss said if im not the first one there tomarrow i'm fired.... please help me! i have new plugs on their way here and should have them here tonight, please any and all help is greatly appreciated

First, don't use ATF to unflood. Just use regular old oil if you must add something.

And based on the fact that the car often floods, and the symptoms you describe, I see two possibilities:

1. Leaking/stuck injector
2. Low compression

thanks for the input, i'll do a compression test this weekend, also what about my bubbling issue? i started the car and topped off the coolent and it kept bubbling up, nothing gnarly but consistant little bubbles but there is no white smoke from the exhaust. i also have to top it off everytime i drive for more than half an hour, could this be caused by a cracked resevior or leaky rad cap? totally noob to these cars and i did search the forum but couldn't find thread describing my situation

The bubbling could be caused by an internal coolant leak. The best way to go about diagnosing it would be to pressure test the cooling system. Keep in pressurized for several days and then check to see if there was an external coolant leak or an internal one (wet spark plug).
