Hello! Just wondering: can fuel get back to tank? I tried everything on my car and just left me this option!!! I say that because the engine, after get seat over night, takes a litte bit longer to start. And if i put it to work and immediatly shut it off, put it back working the car starts normally!!! MAF is fine, coils are fine... My car is a C200 Kompressor from April - 1997. I had a C180 fro 10/1997 and never add this problem.

 

Check fuel delivery, fuel pressure, amperage draw on the fuel pump!!!

Sounds right to me too. And if it is the fuel pump and you need a new one, think about a second mortgage on you house before you take it in. Pricey.
It's great to have a master MB tech on this site, so welcome and thanks for your help if I may say so, even though this is not my thread, you know we all appreciate the input!
