2002 Mercedes Benz C180 car wont start

Has the check engine light come on? Will the engine start at all? Have you checked fuel pump pressure?

i have a 02 mercedes c180 6 speed gear box 2ltr petrol saloon i have it a week and engine light was on when i bought the car and in
the morning when you start the car it will start with the first turn but engine loses power
for about 30-40 seconds and a noise coming from under the bonnet but i dont think its the
engine.. when i drive the car its like its driving normally but today i came back from around
30mile journey and car was started and just started losing power and when i tried to
accelerate there was nothin and car just cut out..every time i try to start it it will start
and lose power then cut out in the space of a few seconds.. please i need help

havnt checked the fuel pump pressure.. i know nothin about cars .. if you could tell me where it is and how to check that would be helpful..any other help you can provide would be much appreciated

Here is a video that shows how to check fuel pump pressure. There are also directions on our homepage under the DIY section.

You will need a fuel pressure gauge. Most parts stores will lend them out to customers, so check your local parts store.

Let me know if this helps. At least it is a good starting point. Also, if the check engine light is or has come on, have the computer scanned for trouble codes. Again, most parts stores will do this for free.

Let me know what you find.

I have one more question. Can you describe the sound you hear under the hood?

its very hard to explain..3 people including myself said it doesnt sound to be comin from the engine..it kind of sounds like something vibrating but when your driving the car you cant hear it.. would it be the spark plug by any chance? like i said i dont know much about cars..thanks for your help

Chances are it has nothing to do with the plugs. Is there any way you could video the engine running and the noise and upload it to youtube or something so I could hear it?
