1993 Mercedes Benz 300sd • 6 cylinder FWD Automatic • 152,000 miles

I have a diesel 300SD. Car wouldn't shut off. Used stop lever on engine to stop. Car will not start until I push the lever back up. Now the car will shut off, but have to push lever back up to restart car. All vacumm hoses have been checked, but no one knows about the lever switch. Can you help me?
