Have a 1993 300zx. Will not turn over. Battery, starter, ignition, fuses, relays are good.

No power getting to ignition switch. I'm thinking anti theft is causing this. How do I bypass this or reset it? Only things working are headlights and power seat. Please help!

Are you using an ignition key with a transponder chip or are you using a generic copy of the ignition key?

I removed anti theft box. Car does same thing. Insert key turn nothing. Have headlights,pwr seat works, but no other electrical parts work. Battery is new.

I don't think it's as simple as just removing the theft warning control unit. Doing just that creates an open circuit in the design along with the ignition and the theft warning relay. On page EL-15 of the FSM shown in the following link, you will find the wiring diagram that might help.

Is your car a manual or auto?
Could be the clutch safety switch if manual, or the park position switch.
Can you here the starter relay in the front dr side wheel click when trying to start?
Maybe the starter just quit working?

These old cars do not have transponder keys.

No power is getting to the ignition. No dash lights,no radio etc... Battery is new, headlights work,pwr seat works but nothing else

Check the wiring diagram. It looks to me like removing the theft warning control unit severs connection with the ignition or maybe the ignition switch is shot.
