HELP! b18A swap completed but car won't start.
 

We recently completed a B18A swap to a 92 DA. First try to start it up the car would crank but wouldnt start. so we swapped the dizzy to another dizzy. Tried crankin it again, it started but this time it ran rough, like it was running on 2 cylinders. we checked and corrected the firing order on the dizzy and tried it again, it still ran rough. then when we pulled the spark plug wires one by one to see which cylinder wud kill, the engine died when we pulled the wire from cylinder 2. so we tried starting the engine again it would crank but it wouldnt start. we did a spark check on each wire with a spark plug but we couldnt get a spark. What could the problem be? we checked all the ground wires, fuses and everything is good. Could it be the ECU, Main Relay, or the Distributor?
