73 Plymouth duster ignition

I need help guys. Put a new coil spark plug wires and starter relay and now car won't start. It fired right up with old relay after replacing cool and wires but when I switched the starter relay it wouldn't crank. I took pictures and hooked up everything exactly the same and still not even trying to turn over and fire. What's going on. Could it be my ignition switch? I even put the old relay back on to make sure I didn't have a faulty part. I don't understand. It did this last week before I put the new parts on for two days then fired right up when I tried it on the third day.
