You won't be able to use your existing rev counter with coil pack without doing a mod to it first,You have got the twin ignition amps presumably? Make sure the engine is timed up correctly. The firing order is 1-3-4-2 not 1-4-2-3. When you turn ignition on FP should prime if not this shows CPS to be faulty. Check the connector on this as the pins are known to come loose and lose connection to the car loom side. Also make sure the gap is ok it can be out be a fair bit and still work but not masses.
