If you dont get 12v to earth on the violet wire at the footwell connector but its leaving the relay it sounds like the wire or a lug is high resistance or a poor contact somewhere...have to check it for a good circuit with a multimeter and a long length of wire for the other return path to test.
Had similar symptoms and it turned out to be the pump maybe its your problem especially if the car had done over 200k.
Turned out to be the actually copper commutator was worn through where the brushes run against it inside motor breaking contact.
Solution was to get another one ...had a drama getting everything to seal again without leaking and getting feed hose off but finally fixed it.
