On one of the diagrams that wire (pink/white) as well as going to the pump has a branch going to a lambda sensor and one other component, without looking it up I cannot remember which one though.
The manuals on the Totally Alfa site show all the wiring diagrams and have fault finding flow charts. See if you can find out which Motronic unit you have and see which diagrams go with that. There are a few! The sections you need to see are 55 29a onwards in each of the parts, mostly the part 3s. You'll see what I mean.
