Crank but no Spark issue.

I have a 1973 Dodge Dart Swinger with a 318 she cranks but does not start, I can smell fuel I have a light spark coming out of the ignition coil nothing coming out of the distributor any ideas. Noted that the ballast resistor becomes warm with key on but never gets hot. Ran fine 10 days ago. No moisture in cap. Plugs were cleaned because of fuel fouling
