If you have a starter mounted solenoid and it just clicks when you turn the key, with a new solenoid, you either have a bad ground  somewhere, a bad solenoid or a bad battery.  Take a voltage reading at the starter, testing for voltage at both the small wire and the large wire, with the key in the start position.  You should have 12+ VDC at both terminals.
