Question Tc72f100 Still having staring problems

Still having problems getting this truck to start on its own. The truck will start if you remote start from the positive terminal to S. but will not start otherwise. What are readings should be found at the solenoid with key off and on at the s and i terminal?

Key off, both will be zero volts. Key on, "s" terminal should be zero volts and "i" terminal should have 12 volts. Key in start position, "s" terminal will get 12 volts and "i" terminal will get 12 volts.

I have seen ignition switches go bad because they will deliver 12 volts to the "s" terminal, but nothing to the "i" terminal.
