22 Denalli lm2 refresh no crank, no start

[lawrenq]

Twice this week, when I went out to start my truck, it wouldn't crank; it just clicked, like the battery was dead.

 

Both times, after wiggling the fuse box, I was able to get the truck to start. After the last time, I torqued the under-hood fuse box to 53 in/lbs, but I haven't driven it much since then. I'm thinking I may have a bad ground.

 

Has anyone else had this problem, and what else should I check?

you may have a problem with the fuse block, but a starter that just clicks with a full chargred battery is usually a sign the starter is on its way out
