why is there no power to start my 2007 denali even with a new battery?
Just bought this truck three weeks ago after a couple days I went to
drive it there was no power, had to jump start. This happened two
more time so I replaced the battery, I didn't drive it for a few more
days then yesterday even with a new battery there was no power .
can you tell what is the problem
Check the connection on the firewall just above the battery. It's in a red plastic box. The bolts can come loose or be corroded. I also had one the I had to replace the ground wire off of the battery. Check all connections along the way to the starter and fuse box.
