Mercedes C200 wont start

[kosthos]

Hi. I have Mercedes C200 cdi, 2004, diesel, the engine wont start . The starter not cranking it's just single clicks. The battery looks fine. We've changed the injectors. Any suggestion? Appreciate your reply

a battery looking fine does not mean a good battery.

You need a get a v meter across and test the voltage as a start, anything below 12.6 is goosed. If low get a pair of jump leads across or a batter charger (better).

Welcome to forum and do stick about

Battery looks fine, or is fine?!
Jammed starter...
Duff relay..
Bad earth to starter..

Just clicks leads me this way.

Indeed, need to start with the battery, then starter and relay.
