More ignition issues on the dart

Hey guys. I have a 74 Dart Sport, Electronic ignition. I’m having an issue all of a sudden where I’m not getting spark. If I disconnect the distributor wire and touch it to ground, I get sparks out of the coil wire. But when I plug it all back in and turn the key, I get one spark when the engine starts cranking, and one spark when I let off the key. So the engine sits there and cranks and does nothing, but occasionally if I let off at just the right time it’ll fire exactly once… what’s the deal? Anyone else had this issue? I’ve tried jumping out the ballast resistor, but to no avail
