2001 Chevrolet Silverado 1500 - Power drain

im having the same problem … start it once daily let it run for 15-30 minutes , wake up the next morning and there is no power… constant drain somewhere just dont have the tools to troubleshoot it… when i go to start it i get that clicking sound like the starter is not fully engaging…

Go to AutoZone, etc. and have the battery and alternator tested. If neither is bad you’re correct that there’s a “parasitic draw” somewhere and you’ll need to take it to a good independent shop for a diagnosis.

Do you think we can do that troubleshooting for you over the internet? Sorry, we can’t

Suggest you take it to a shop that HAS the tools and knows how to run a parasitic draw test.
