When you hold the pedal down while trying to start, you're not really
"giving it gas."  You're opening the air intake, which is a good way to help
start a flooded FI engine.  So it sounds like you might be running rich,
even while trying to start.  What do the plugs look like?

Yes, do this.  I think I described earlier how to make a good $10 gage from
hardware store parts and 5/16" fuel line.  This hooks to a T fitting between
the right-hand-side injectors.  If your pressure is too high (more than
about 30psi), this might be a cause for running rich.

Again, real easy.  VOM across the battery posts.  Engine warmed up and
revved up a bit.  You can also measure at any point on the fuse block.

If the dwell moves around, your dist. shaft is worn.
