Dead fuel pump or dead fuel pump relay. Which? 140-160 1973

posted by  someone claiming to be Dick on  Wed Aug 25 02:21 CST 2004 [RELATED]

I have a 1973 145 wagon with the D-jetronic fuel system on it. It's been stored in my mother-in-law's garage for over three years. Not too long ago I went to start it, but did not get the customary 1-2 second hum from the back fuel pump, telling me the fuel injection system had been pressurized. Of course it did not start. Before I tear into the fuel pump (which is covered in thick underbody coating making it hell to remove), is there a way I can tell from the fuel pump relay on the inside fender well, whether the fuel pump is okay and not the relay? I know there is also a plus/negative factor to be aware of in testing the fuel pump. Can anyone help me here, and also which relay (and the flat pin contacts) on the inside fender well is the fuel pump relay? There are two that look exactly the same. Dick
