My car only starts in neutral and had the neutral safety switch replaced.

I was able to buy the part myself because my friend works at a auto shop. I bought it at a Mazda dealership. I originally bought one from autozone and had it put in but didn't work at all. So I had it done with a dealership part and it worked perfectly for about a week and then it stop working less and less each day like it had to start with. It was replaced by licensed technician at an auto shop.
