Get a meter or test light and test for power at the starter button
Ok both sides of the button
Make sure you got power going to the button
If not then track that wire back and test it at every connection back to the battery
If you got power coming to the button and power out when you mash it
Then track that wire to the starter relay and starter and check for power at every connection
I’m not sure which side of the button the neutral switch is on but you’ll find it when you track the wire
To test the starter itself
Just use jumper cables from the battery to the starter motor itself
Doing that will bypass all the other wiring , switches and relays and let you know if the starter itself is working
And like the other poster mentioned
Hold down the starter button and whack the starter motor with a hammer
Sometimes that fixes it
