For the first time ever my '02 Impreza RS decided not to start today. It was
60 degrees outside, not raining, parked on an incline, had a good 1/4 tank of
gas in it, etc, etc. It started without any problems four hours before when I
went out to lunch.

The battery seems to be working fine and the starter made all the right noises,
I even tried jumping it off my friend's car, but no dice, not even a hint of
the sound of the engine turning over.

As per the owner's manual, I tried starting it with the gas pedal all the way
down three or four times, tried starting it with the gas pedal half-way down,
and even "lightly depressed"...still nothing

Fortunately, this happened in front of my office and I was able to get a lift
home, so I'll have time tomorrow to fool around with it. Is there anything
obvious/simple to fix that I should be looking for before I give up and call a
flat bed? [And yes, the car just happens to be 4 months and a few thousand
miles over warranty...f*ck]

The only other thing that probably isn't realated at all is that I yanked open
the fuse box next to the engine this morning to put away the fuse puller. So
it's remotely possible I knocked a fuse loose in the process, but none of the
fuses felt loose.

Any ideas???
