  The fuel injected into the air depends on the injector
duration and the fuel pressure.

  If you are getting way too much fuel, is there any chance
a blockage is causing a really high fuel rail pressure?

  Also, most systems use a vacuum-attached fuel pressure
regulator. This keeps fuel pressure at the correct ratio
from manifold pressure to keep volume of flow the same. I
can't imagine a mode of failure that would cause this,
but positive pressure on the vacuum line will impede
the operation of the regulator.
