MERCEDES NO START PROBLEM

[spanaz1]

I have c200 w202 .When I put key in ignition the handshake is there and key turns all lights on dash but when I try to start nothing happens. At first it would refuse to start but when I take key out and try again the car starts. What can be causing this..

My problem seems to be similar, except when taking key out and trying again, nothing happens. (I have c200 cdi). I had a camshaft position sensor replaced 1,5 year ago. Could it be possible it same thing again?
