I drive a 2015 Tahoe. When I turn my key it will click once and then nothing. It will turn over after the third attempt. I went to O'Reilly and the starter, battery and alternator are all good. Any Advice?

 

bad ground somewhere. I have had that also.

Create a ground cable attach it from the negative pole to a bokt on the engine. Beware so the cable does not get hooked in a belt or so.

If it then works, u need to find that ground cable somewhere attached to the body. I think somewhere behind the motor againt the torpedowall.
Check the main ground cable, could be rusted of.
