300E won't start..

ok,i'm completely new to this, my car 1986 300E won't start at all, I don't even know where to start. It seems like it's not getting fuel or something. Can anyone advise me on how to diagnose the problem? I'd rather figure it out myself then go to a shop and get ripped off because I'm a woman.

To start, do you hear any humming/hissing from the right rear of the car when you turn the key on (lower the rear window)?


it starts sometimes and sometimes it does not. In my honda, I had a similar problem, and it was just the main relay.
