Mercedes Benz repair: repair quaestion, fuel distributor, cold start

Question
I have replaced the fuel pump and still have no fuel to engine. It turns over and has spark  

Answer
have you checked the fuel pressure relay? google it to see which part you need you can jump pins 87 and 30 to check to see if pump is working. Otherwise pull an injector and make sure you are getting fuel to them if not then either your fuel distributor or regulator is gone you will have to diagnose the problem peice by peice, seperately.  also check your cold start valve and make sure fuel is getting to it . Did you change the filter along with the pump??
