Hello there--
I'm having a problem with my 2007 Chevy 2500HD when I try to start the truck. It happens about 4 out of 5 times and just started happening a few days ago.
The truck is in Park, I turn the key and get a buzz, at which point I turn the key to the off position and try again and usually the truck will come one at this point.

Here's a sound file of what it sounds like when it has the issue:

Here's one of a normal start:

I appreciate any clues anyone might have. Thanks.
