I'm considering buying a 1991 sl 300 that won't start
because of a malfunctionimg security system.
How can I unhook the security system so the car will
start? I don't think unplugging the module will work.
Can i unplug the module then run a 12 volt wire to the
fuel pump relay ???
Please help !!!

Saw that car on eBay too! Wonder how the seller knows the engine and transmission are okay if the car won't start! Anyway, the security system does not disable the car from starting on a '91! This feature was not introduced until...I think it was '93 model-year.

I did too and totally agree with Bob about "Wonder how the seller knows the engine and transmission are okay if the car won't start!". Some just said whatever to sell their cars.
