If you look back abit further you'll see that someone had swaped E1 and FC in the harness plug.
These two issues resulted in the pump being energized any time the key was placed to run.
.. There is no magic wand that replaces testing, TEST do not guess!

sometimes it simply means the afm thinks air is coming through. Sometimes from people play with the afm, Usually from people popping the cover off and not resealing it.
