Negative. Not since I've had the truck. That is sorta uplifting news that it may be the CPS. My dads 05 Sierra was plagued by a similar issue. Would run like a top, but sometimes you would hop in the truck and turn the key, and then nothing. Identical to the video I posted. After 10-20 tries it would fire right up without further issue. Hooked my cheap blue tooth scanner up to it and it flashed a code for crank position sensor. Perhaps this is the problem.That's a good bit of info right there. Have you replaced the starter recently?

Wouldn't I need to do a crank relearn after swapping the sensor?
