The starter worked this morning, now it doesn't.

Just making the suggestion. I've had my car do the exact same thing (actually, not only the FC but my VW at one point also) and the battery just didn't have the umph.

Probably a starter.

EDIT: Also, before you remove it, try giving it a few love taps. Sometimes when a starter's on its last legs a section of the motor will be sticky due to wear and a little wrap is good enough to free it up. At least that would solidify the starter as the issue if a tap got it spinning again.
