_It's been a long time since I've seen a bad starting safety switch on a vehicle. But today I have seen one on an older Nissan 300ZX, a 1989 300ZX to be exact. I call it the starting safety switch but often this part is called the neutral safety switch.

_It is a normally open switch that prevents the starter from operating when the transmission is in any other gear except park or neutral. This eliminates the possibility of a situation that could make the vehicle move forward unexpectedly or in reverse as well.

These starting safety switches or neutral safety switch whichever you want to call it are more commonly used with automatic transmissions but in this case of the 89 Z it was a manual transmission vehicle.

I am familiar with the Nissan ZX as I owned a 1988 model. In fact I have written quite a bit about my Nissan 300ZX problems. And although I had a lot of problems with my little sports car this was not one of them. I had to find the component location diagram and verify the color of the wires to properly by pass and test the switch.
