2008 Tahoe No Start

[weber_d_max]

Hi guys i'm new here and I have a 2008 Tahoe and it will be running fine one minute and if you turn it off and go to restart it does nothing. I have to jump it to get it going and then when I test the battery it test good , so I put a new battery in just to make sure and it still does the same thing and its not consistent. Any help would be great Thanks

It could be your alternator. I had the same problem a few months back. I changed my alt and now he runs like a charm again. Also i bought a higher output alternator from O'Reilly to keep things cost effective.
