"Do I have multiple issues here?"

The odd voltage reading is due to the very high input resistance of your multimeter. It is reading a voltage that has enough current potential to register on the digital scale, but not enough to appreciably light an incandescent test lamp used in the "old days" and not enough to operate the starter solenoid.

That small current originates in the ECU through R133 shown in this map of the ECU's circuit which senses the shifter position. Below you see this connection to the ECU (214) in the dotted-line reference from the test socket. Pull the plug on the ECU and this mystery current will be gone.





If I got the readings you post, I'd be thinking "swap the starter."
