I'd suggest looking at the ignition switch first, then the BCM, and finally the wiring at both locations. When the ignition switch is turned to the start position a starter request signal is sent to the BCM. When the BCM determines that the correct key is being used, which should happen immediately, the starter is engaged. It sounds like there's a delay in the BCM receiving the starter request signal or a delay in the BCM enabling the starter. Hope that helps! Jim

This started happening on my wife’s Equinox V6 and found that the starter was getting ready to fail. When I pulled off and looked behind the end plate the brushes were ground down so far they were arching.
