Thanks for letting me into the forum, I used to be a Dart owner but I just bought a non-running 1972 Challenger and its not getting any spark to the plugs. It is a 340 with automatic transmission and I have replaced the ballast resister, coil, ignition control module and battery. It cranks like it should but I found when cranking I am only getting 6.8 volts across the coil contacts and only 4.2 volts with the key in the run position. Any help would be greatly appreciated.

Start checking connections , the firewall bulkhead & the connector at the base of the column , you must have a corroded or loose connection there or a bad ign switch , you need 12v cranking , 7v running at the coil .

Welcome to the site too !

Bulkhead and connector look good, I am wondering if the pickup coil in the distributor is bad. I have read online that you must remove the distributor to replace it but looking at it it seems that I could replace it without removing the distributor or am I missing something?

Welcome! That’s about all that’s left (unless a new part is bad) cap and rotor inspection? if you haven’t.

After I installed the module and it still didn't start I pulled it out and took it back to Autozone and they put it on their tester and confirmed that it is good. Cap and rotor look to be brand new.
