Well you should follow the write up in the FSM on how to inspect and test the ignition system. but in a nutshell dissy tells ECU where the rotation is via 2 signal pulses 0 and 120 degrees. ECU sends signal to the power transistor which fires the coil to the rotor and out to the plugs. The ECU modifies timing based on conditions so although it is dissy during the rotor pad overlap there is time to compensate for timing advancement or retardation.

with that said follow the FSM and do some testing, could be the power transistor (coil), ECU, harness
