2000 Honda civic with obd0 motor no spark?

i took out my type r motor and put in this single cam to get rid of the car. I tired a 2000 civic ex engine harness no spark, then i changed the dizzy and nothing so i changed the plugs and the ecu and the engine harness. so now it has a 2000 si engine harness off the type r and running a 2000 si ecu and a dizzy that i know that works and still no spark wtf?
