73 Plymouth duster ignition

No just replaced parts yesterday. Yes I believe it is electronic ignition. Also it's a 318. Nothing happens when I turn the key. That's what I don't understand. A friend told me I might have ground issues as well. I'm gonna check battery later. Last week it was not doing anything with key turned and checked it one more time just out of curiosity and cranked right up. Even with bad coil connection. Yesterday changed out the coil, spark plug wires and starter relay and again nothing.
