• the hood is most definitely not open, and even if it was falsely detecting that it was, wouldn't it show something akin to a "door ajar" message on the dashboard?
• The van is definitely in park too.

I've recall reading that if the remote start fails to work there's supposed to be an error message that will show where the odometer is. I've never seen such a thing. That leads me to believe that it's not even properly receiving the signal or there's some hardware issue with the remote start unit itself. Does anyone know if there's any wiring diagrams out there on the internet or information on where the remote start unit is? I assume it's somewhere behind the paneling around the ignition switch like a third party remote start would be, but I'm not certain on that and would rather not start taking things apart unless I know what I'm looking for.
