No crank no start when key turned

Welcome to 2CarPros.

Here are the directions for replacing the switch. I'm not sure what you are jumping to start it. If you need a wiring schematic for a specific component, let me know.

Welcome back:

I'm a bit confused. The switch itself is attached to the key cylinder. That is what the directions were for. So, I'm not sure what it is you are trying to replace. As far as your question, if you figured out which wires cause the starter to engage, then yes, the ignition switch would need to be in the run position for the engine to run.

Let me know.
