The fuel pump (0580 463 009) on my 71 quit working. Even with power connected directly to the pump it did not work. I replaced it with a spare pump (0580 463 005) I had. This one only builds pressure if I switch the positive and negative leads. It will run when connected normally but it will run backwards and will push fuel down the return line. Anyone have any ideas as to why this is? The car runs OK with the wires switched.

The car has the original D-jet fuel injection system.
