2001 Camaro SS won't start

Car won't start, turn key and only get clicking sound similar to dead battery. It started when jumped and ran fine. Connected battery to charger for a few hours. Charger showed battery was fully charged but it still won't start just clicking sound. I'm thinking it is a bad ground somewhere. Where are all of the grounding points? LS1 V8 engine, manual transmission.

Sounds like a bad starter solenoid. Starters go out without warning.
