Does anyone know where I can get a workshop manual for my car. Im looking at knowing where I can find my fuel pump and testing it? The fuse is alright in the boot but when I turn the ignition on there is no noise and at the injector rail there is no pressure so I'm guessing I have a problem with my fuel pump.

Haynes do a workshop manual for the W203 - number 4780 it covers all models with the exception of the 6 cylinder engines.
Would I be right in assuming that yours is a petrol engine?
I can probably upload something that may help you, but don't want to post details for the wrong fuel type of car. Manual covers both petrol and diesel.

OK, give me 10 minutes.
It seems that they do an online version of the manual now for a one off payment of £25, but check the 'system requirements' before purchasing should you be interested in that option. http://uk.haynes.com/products/productID/21

While I'm scanning the info, this may also be of use. Have you checked the pump relay? See rear fuse box info in this link.

Sorry it's a bit untidy, difficulty keeping images the same size when cropping them. HTH.
That is fantastic. I was looking on line and some say the pump is separate but this is what my pump is looking like. Just making sure I wasn't being stupid. As you suggested I had a look at my relay. Now before it wouldn't start but I removed the relay, cleaned the terminals and replaced it and I fired up( only for a second or 2) but now to me that sound like the relay is not staying in?????

There may be an identical relay in the rear fuse box which you could swap over just to try it. Check the circuit diagrams which are usually marked on the relays.
Otherwise for the cost of a new relay, it would save a lot of hassle removing the pump until you're sure it is that.
