SWITCH TURNS OVER, BUT NOTHING HAPPENS.

1997 GMC Sierra • 144,000 miles

My switch turns over, but nothing. I changed the battery and starter also checked all fuses with a meter and all good. I'm about to change the ignition switch. Any ideas?
Thanks and Semper Fi, Grant

Check to see if power is going from switch then it goes to nuetral safety switch. It also need to get a signal from the pcm to the relay then to the starter.

Where is the safety neutral switch located? I'm pretty sure I have power from relay to starter, but what's the best way to check? Thanks!

The nuetral switch is on the trans it's the purple wire going to relay to tell to start. There is also a crank fuse in ip block on left side of truck. There is also a 40 amp fuse in underhood block make sure those are ok.
