I installed today, cranks, but no spark. Not sure what the problem is.

Coil is MSD Blaster 2. Was working yesterday.
MSD wires. They were working yesterday.
AC Delco R43S spark plugs.
12v+ keyed power to + side of coil verified.
Distributor ground is to a firewall stud, where engine ground strap grounds to firewall, power probe confirmed it is a solid ground.
Supplied wiring harness is connected property, distributor to coil and tach.
Vacuum line is connected.
