My 94 300zx wont start when you turn the key. The radio turns off and the antenna will lower but all the lights in the dash stay on. The engine will not turn over and the starter wont click. Battery power is good.

sounds to me that you have a faulty ignition switch, are you using a coded key and is the theft light on? if no then check the ignition switch.
