I'm afraid for you - very afraid for you actually. I'm hearing control module.
A coil is charged and needs the primary field to discharge to create a spark on the secondary. That primary discharge occurs via shutting off voltage to the primary positive lead, or opening the negative lead of primary (which is done very rapidly by the ignition control module in this case, or the breaker points on a B43G).
Clean your connections, ALL OF THEM INCLUDING GROUNDS, check your ignition switch, and pray.
