I have a 2016 zforce 800 ex , having starting issues. I can turn the switch sometimes it starts right sometimes does nothing, if I keep bumping the switch it will start. I have replaced the starting diodes, the starter relay, and had the starter checked for dead spots,  artery is good. Anyone have any idea what problem might be?

If it's not a bad connection in the harness it going to be a bad switch. Does it do anything else strange when you turn the key to the starter position when it does nothing? Try this-turn the headlights on and watch them when you hit the starter. Do they go out? or not when the starter is activated.
