So I bought a 2006 v6 Convertible that had been sitting for over 2 years. I took out the starter and tested it at AutoZone with their test machine and it passed just fine and I got a new battery.

I took out the starter relay and made sure it was fine, and jumped the 30 and 87 pins on it and you can hear the starter click out but no spin so I’m pretty sure there’s a loose ground or I’m not getting enough voltage to the solenoid.

I’m pretty inexperienced when it comes to electrical issues...
