Failed CoP

[hrforever]

Been chasing a miss under power and have discovered a CoP unit has failed. Whilst the unit makes all the right noise when in test mode using the MS3, there's nothing going to the spark plug.

I've placed a wanted ad for a replacement but I'm interested in the failure and where the fault is. Item is a Toyota 90919-02230.
