Fuel system leak?
I've recently purchased a W210 chassis E200 (M111). The car starts very poorly - cranking for maybe 5 seconds plus gas pedal tapping, especially when warm, but when it finally starts up, it holds idle perfectly, doesn't smoke, and just all-around functions well, I don't even think the fuel consumption is out of the ordinary (judging from the fuel gauge). I smell gas coming from the front of the vehicle, and the fuel pump whines while running.
Thank you for suggestions on what the problem (or multiple problems) could be.
