1985 Mazda RX7 will not start

Ok here is how it work. The distributor has a leading and trailing pickup coil inside and when the the leading pickup coil is triggered it send a signal to the leading coil and fires the leading spark plug, then right after that the trailing pickup coil does the same with the trailing coil and spark plug. So what I would test is the trailing pickup coil in the distributor. If you would like I can walk you through the test if you have a digital multi meter. Get bck to me

can the trailing and leading pickups simply be changed. How do you test for the trailing pickup. Please provide step by step.

Follow the pick below for pick up coil testing it should read 600-700 ohms

This is the plug between the ignitor and distributor.
