The pins dont have the metal thing to make good contact. Do they sell them?
I don't know. Maybe you could post that question.

Pin A from the dist. plug is reading 12v but the test #3 failed. When I jumperd the pins B and C and removed the wire there wasn't a spark and the fuel pump did not turn on
.
What about the (nominal) 5.0v on Pin B? And the Ground connection for Pin C? (see test #2 again). If all 3 aren't correct, that might explain the test #3 failure.

I didnt do the other Hall Switch tests because I figured if the ICU failed the other tests wont be much help.
I agree with your logic, but we don't yet know for sure the ICU is really bad.
Could be a Pin B or pin C problem,
or any of several potential wiring issues.

They say not to pull the ICU connector and risk damaging the sleeved pins.
Do you think you could "back-probe" those pins?
If so, I can research some voltages to test for.
