Has key power, swapped module, distributor appears to be be pristine. Can I use a spark tester between coil & distributor to determine if coming out of coil?

Yes you can. but use a small engine spark plug tester. Do not use an HEI ignition tester because the gap is too big. I prefer the KD 2757 if you can still get it. The 2756 is HEI and may blow your ignition module $$$

2757 KD Tools Standard Ignition Tester

Standard Ignition Tester is Calibrated for Standard Ignition Systems Accurately check for spark in ignition systems without removing spark plug from engine.

Test lamp from coil neg to ground. Does it flash when cranking? If not ignition module not working. Do a continuity test on the ballast resistors. Rotors often short and direct spark to ground.
