230CE Fuel Pump

[merced230ce]

I have a mercedes 230CE made in Europe 1984, altho' they were not officially made that year. It was specially made for my father. The engine quit without warning, would not start. My husband did work and determined the fuel pump is working. A new filter is put on, the fuel pump "buzzes" when the key is turned on, which should indicate that fuel is being delivered. Now the engine runs for about a half a minute then suddenly quits. This occurs repeatedly with the engine always quitting in short time. What else could the problem be?

Well are you sure the fuel filter was put in correctly? Hey you never know
Sounds like there was attemp to correct an existing situation with the fuel filter change. Check the whole system if you can. Check the fuel pump check valve, fuel pressure regulator and eye ball the fuel lines.
