Car do not start when cold

Hi
My mercedes do not start when it is cold and idle rough when it reach working temprature.
I check the cold start and replace the cold start temprature switch. I also check the WUR and find nothing wrong.
I also check the fuel pump and acumulator and find that the acumulator hold pressure and fuel pump work corectly.

​​​​​​​Any sugestions?

Plutoe, he doesn't say but from the description, sounds like a gasoline engine.
