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
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.
