6.6 Gas Chevy LT 2500HD Question: 

I had the hood open for a couple days and when I went to try and start the pickup it was dead. I figured I could leave it open as there was no courtesy light underneath the hood.

Is there something that would drain the battery by leaving the hood open?

 

Thanks!

Unless the BCM retains power on a circuit due to the sensor showing the hood open there should be no drain on the battery from it. You may want to check to see if there are any campaigns open on your truck for electronics. The one just done on my 2024 did help with battery running down.
