Help Please!! 1993 RX-7 won't start...
 

Ok i am new here so if i am posting in the wrong place i apologize. I have a 93 twin turbo RX7 that i just bought, i have had a few older rx7s in the past so i am somewhat familiar with them, but this is my first 3rd Gen. I bought the car knowing that it may need rebuilt, it was not running and i towed to my shop. Me and my dad run a repair shop here in town and i have been working on cars all my life. The car seems to have good compression, it gives three steady puffs on both rotors when plugs are pulled, it has good spark on all four plugs, and it is getting fuel. It will crank all day but never start. When egi fuse is in, it will give a couple puffs out the exhaust at first like it is trying to hit but it will never fire up. I have tried pulling egi fuse and cranking with pedal to the floor and then putting fuse back in and cranking without pedal to the floor several times, and i have pulled the plugs out and cleaned them or replaced them and tried the atf trick several times also. I am stumped. Car has 110xx miles and was supposedly rebuilt at 80xxx. Car is mostly stock other than intake and exhaust, and is automatic. Any help would be greatly appreciated!!
