C180 Kompressor Coupe
![Unhappy](https://mbworld.org/forums/images/icons/icon9.gif)
Hi Guys,
Lately i have had issues of my 2003 Mercedes C180 Kompressor cranking but no start. After inspecting i've seen that there is no fuel pump operation on my vehicle, so i have replaced my fuel pump. After a few successful starts i've encountered the same problem again with the car cranking but unsuccessful in starting. I've tried tapping with my rubber mallet around the fuel sender and asking someone to crank the engine at the same time allowed the car to start. Once having a look at the fuel sender and removing the 5 pin connector on top of it, i realised that the metal connector of the brown (ground) wire was fried. Im just curious to know why this has been burnt. Also as to what each wire on the connector represents. I am aware the black/green stripe wire is positive that powers the fuel pump and the brown wire is ground. What are the other wires used for and are the black and brown wires used to energise the fuel pump and sender at the same time?
Thanks
