I put a new throttle body in my car, why it still won't start??

Question

I went to autozone for them to check my engine light. The codes was P2101 P1516 P1682. The man told me if I put a new throttle body in it'll fix two codes. I did put a new throttle body in today & it still will not start. It's trying to crank but it won't start, you can hear it trying to connect. I have a new crankshaft sensor, fuel pump, spark plugs, & now a throttle body. So if I fix the ignition 1 switch circuit 2 , it will start??? I need help
