Sorry for the late reply.
After 3 days of troubleshooting, I prayed for wisdom and guidance. (Why is that never the first thing I do?)
I decided to start where the problem started - when I disconnected the coil pack.
I removed the connector and started looking. Directly underneath the coil pack connector was a connector with 5 black leads bolted to the block - grounds! One ground wire was busted off at the connector end. I peeled back the brittle wire cover, peeled off all the electrical tape, and the broken wire was from the coil pack connector! I crimped on an eyelet, cleaned up the ground connector, bolted it all back to the block, and VA-ROOM! I am SO fortunate!
