I don't think the pump spins unless the engine is cranking.  Have you
checked/replaced the fuel pump relay?  I had a bad one that kept the pump
from spinning while the engine cranked.  Of course, a month after I
replaced the relay, the pump died.  I suspect a failing pump maybe stressed
the relay.

Pump rotates clockwise for extraction (I THINK--it's been  a year).  You
have to budge it out of a detent and then it moves easily.  I couldn't get
it to move by hand and needed the extraction tool ($25 from
Zelenda).  Others have found a leather glove gives them enough grip and
hand protection to turn it.  If you look with a flashlight, you should be
able to see at least one of the detents and determine which direction is OUT.
