Sorry for the late reply, and thank you Richard for the wiring diagram.
After some hours fun with the diagrams I realize a seven pin part is driven by five wires. I think that‘s the point the car doesn‘t „see“ the problem and you can‘t see it in the OBD.
And when I went from the fusebox to the back I measured the wires at the connector. With the four pins bridged, the fifth pin (W36) shows 2.6V. As I learned (thank you also Richard) a usual voltage out of the ECU. So no problem there. No waiting for a call from FORD Bingen about „the part“.
Also about „the fifth pin“ W38, in a time not knowing Richard’s post about the ECU, I had a deeper look at the wiring diagram.
From the back the wire runs to the ECU. And changes the code to W97 at the connector main wiring to the back and W61 from the main wiring to the ECU to PIN81.
In summary I learned a lot about modern car electric. Not only that it doesn‘t work with 12V, some Volts less are usual. And the (for me) „new“ named wires are not so bad and with a little (a lot of hours) thinking it‘s very helpful and not so far from the old LUCAS style.
Now I hope for a „nice firing up“ with the new fuel pump driver or however it would be named.
