MG MGF Technical - Fuel Pump Problems - Help!!

Yesterday my fuel pump seems to have decided to stop pumping. Probably my fault it stopped. Any thoughts or suggestions there?

What I have observed did.

I was replacing the battery cables and adding a ground side cutoff switch on my car. During the same install / electrical work I was adding both a voltage meter and a vacuum gauge.
When I pulled the battery, the ground wire that goes to the fuel pump was caught on the battery base and broke. I could not see where the ground cable went from the top of the battery compartment.
I could only see a spade connector and a silver or chrome piece what I thought was the end of a bullet connector.
Without doing anymore investigation, I pulled that connector out (not easy) and soldered the ground wire to it. With an ohm meter, it did show it was grounded. I then hooked up the wires and reinserted the battery / battery cables.
The new cables and the cutoff switch worked perfectly. The car fired up and ran.
When I turned the key, the voltage meter did not register. I had tapped into the same line as the voltage for my radio which also did not work.
I ran the car several times and for several minutes trying to trouble shoot the problem and it shut down

Mistake correction:

What I orginally soldered the ground wire to was the breather pipe, not an adjusting screw.

thanks for the load of memories Your posting revealed ! Many years back when I was doing Mini-rallying in the deep forests of Sweden 2 SU pumps was a minimum to reach the end of each stage ... Saw in one of the mags that there is a nice solid state switching avaible for those pumps now.
