The distributor is connected to the small negative terminal on the
coil. The ignition switch is connected to the small positive terminal
on the coil. Check to see if you are getting 12 volts to the small
positive terminal on the coil.
good luck,
this reminds me of a good practice. If you have someone replace parts
and it does not cure the problem. Ask for the old parts as they are
yours and apparently they are still good.
Nothing like spare parts to switch to locate a problem.

money; what a concept!
Also, check the coil wire that goes to the distributor cap. That may
be broken.
