RE: How to test coil with igniter
To test the coil (alone) you always could do it the simple way by hot-wiring it.
Wire the + of the coil directly to the + on the battery (disconnect the rest) and just touch the - of the coil with a loose wire connected on the other end to the - of the battery.
The coil need only a few milliseconds to fire (dwell) so don't connect it too long on the - or you will fry it.
Also don't forget to connect a spark plug on the output or it will arc at your hand.

By the way, did you check if your distributor was aligned properly ? if the rotor is not aligned with one of the post on the cap when the ECU try to fire the coil you obviously don't get any sparks.

Finally, ESA (MAP) or VAST (AFM) ?
