First thing to do is LISTEN on FIRST start of the day to the pump PRIME, if it does PRIME first thing then you have a clean CPS signal, the gap is 0.6mm to 1.0mm, but they will still work wildly outside of this.
Next make sure the PHASE sensor is plugged the correct way round, the top wire on the sensor, MUST go to the pin the dizzy body(connector) NEAREST TO IT.
The gap of the phase is 0.2mm to 0.3mm.
Alignment of the phase sensor is critical though it will not stop spark occuring, just throw out fuelling.
