Starter won't crank over when you turn the key, but turns over with a remote start switch. Replaced the ignition switch, but no help??????

You will need to check all of the connections between the ignition switch and the starter solenoid. Seat belt relay under passenger seat, there are two on the relay board alone, and then the relay board itself. Also the connector at the solenoid on the big yellow wire. Is it in good condition? Especially at the crimp.
