After replacing the steering column, it will not crank or start

Clearly, we need to assume that the ignition switch is the issue since it was working prior.

We are going to have to check the crank output on the yellow wire coming from the switch.

Basically, just back probe this wire on the ignition switch connector and crank the engine. You should have 12 volts on this wire.

If you don't then either the switch is faulty, or the connection is not tight.

Here are a couple guides that will help with this:

Below you will find the connector view that will show that we need to check the voltage on terminal C of this connector.

Please let us know what you have on this wire, and we can go from there.

Thanks
