CFL bulb won't work upside down in a particular light fixture

 I've got a hanging light fixture in which I can't get CFL bulbs to
work. They work fine screwed upside down in my garage light sockets,
the bulb is confirmed working in other lamps.

Standard bulbs work fine in this same hanging fixture. Any theories as
to why the CFL bulbs don't want to work in it?

Have you tried more than one bulb?  If not, it could be that this
one bulb is somehow bad in a way that it is sensitive to position.
Otherwise, I'd suspect a wiring problem with the fixture.  Check
to see if it is grounded properly, and that hot and neutral
wires are connected the same way that other fixtures are connected.
Finally, put in a conventional bulb, and see if that bulb is the
same brightness as that same bulb is when inserted into a
different fixture.  This should help you determine if there is
a high-resistance or bad connection in the line feeding this
socket.

Bend the center contact up. Some CFLs don't go into the socket deep
enough.

I was going to suggest the same thing, but let me add that you make SURE
that power is off when you do this.  The switch off may not be enough,
pull the breaker.  And while you are at it.  make sure that the switch
is in the hot side, not the neutral side, and make sure the hot goes to
the center contact, not the shell.

Just stick in a screwdriver and touch the center to the shell and you can
be sure wether or not the circuit really is dead.
Then you can use the same screwdriver to bend the center contact up and be
insulated via the screwdriver's handle the entire time.
