Truck won't start, OBD and Passlock sensor lights illuminated, battery charged. on 2007 Isuzu i290 Pickup

Went out to start my truck this morning and it would not crank. Hooked it up to the battery charger and after less than 10 minutes the charger read "fully charged." When I turn the key, my radio and all other features work, however, it won't crank...just a click. The OBD and Passlock sensor lights are illuminated when the key is turned. The only other time I have had an issue with this truck is when getting gas and they didn't close my gas cap.

Check for battery voltage to the starter...if >12.5V = bad starter, if <12.5V = high resistance in wire to starter...
