Help! The batt is good. When the key is turned there is nothing. I can hear a small click or the sound of some juice getting to the starter, but it will do nothing. Took the old starter off and it tested good. Replaced it anyway w/ a new one and still nothing! Could it be some switch/relay, anti-theft issue, or what???

Typical Nissan problem area is rotten main gnd from batt to chassis, connection under batt tray.
