I had a similar issue with a Nissan a few years back.  Solution was to
pull the
fuse for the fuel pump and try starting it.  The car would start and
run for a few seconds,
just enough to drain all of the fuel out of the lines.  Replace the
fuse, hold the pedal to
the floor and start the car.  This model/year Nissan had the tendency
to flood itself and
this was the only way to clear it out.

Hope it helps, let me know.
