i have a mercedes s320 i have to press the gas pedal to start how do i fix it?
Check your fuel system. I suspect you have low fuel pressure. But it could be anything to a faulty fuel pump, clogged strainer, clogged filter, to a faulty pressure sensor, clogged injectors or a vacuum issue. A good diagnosis is key, you don't want to just replace random parts hoping the issue goes away.
