Ive just did the rb20 swap on my s13. now, I have a problem. the motor cranks, but wont start. theres fuel going through , but no spark, and also my green relays click nonstop when the key is in on. do you think I may have a bad ignitor or bad relays. also I dont have an o2 sensor, havent got 1 yet. can someone please give me some info. thanks.

who did the wiring ?

it could be that one or two of the wires have been crossed.

If the CAS is bad you would not get any Fuel injector pulses.

Make sure your getting fuel IN the cylinders

Check the FSM for the Ignitor procedure
