Hello, thanks for writing in about your Oldsmobile Aurora. A bad starter solenoid could make the starter run, but would not activate the ignition switch, so the engine could crank but not run on its own. I would recommend testing and/or replacing the starter solenoid. If you need assistance with fixing this issue, contact a certified technician, like one from YourMechanic, to diagnose the starting issue firsthand and help you make the necessary repairs.
