If your 1991 Mercedes 300E only starts in neutral, it is likely due to a malfunctioning neutral safety switch. This switch prevents the engine from starting in gear to ensure safety. A faulty or misaligned switch may not detect that the transmission is in park or may have a weak connection, allowing the car to start only in neutral. It’s advisable to have the switch inspected and replaced if necessary.
