2007 Silverado Starting Issue

[krww06]

My 2007 Silverado (38k miles) recently developed a starting/non-starting issue. When you move the key from the off position to either the ignition on or start position it either works exactly as anticipated OR nothing happens at all. By nothing happening I mean literally nothing happens, almost as if there is no battery present (no dash lights, no radio,; no accessories, etc.). Thus far, it will eventually start after you cycle through the starting/ignition routine a number of times with the key. It’s a DD and this happens at least once/week. The battery has been tested at the local battery store and it tests perfectly. Any thoughts as to what to what the issue may be as I fear it’s only a matter of time before I get stranded somewhere? TIA.

Ignition switch is bad more than likely

Battery connections tight?  How are your grounds, clean or corroded?  Any broken ground straps?  Underhood fuse boxes are quite common on this 99-07 and 07-13 trucks so that's a place to check out as well.  Corroded or burnt terminals on the underside of the box, corroded or burnt wires in the connectors to the box.

Exactly.

 

I'm now thinking a loose ground wire might be the cause. Anyone know which one might be the most likely candidate?
