2013 Chevy Spark intermittently no starts

I have a 2013 Chevy Spark that was showing symptoms of the starter starting to go bad. You would turn the key on, all the dash light come on, but you go to start the car, and nothing would happen, not even a clicking noise. Tested the battery, battery is good, replaced relay with a new relay and it did the same thing. Replaced the starter and the car continues to do the same thing, intermittently, sometimes it starts, sometimes it doesn't. I was thinking it could be a bad ignition. Is there any other trouble shooting things I should do to figure out this perplexing problem?
