What is fuel pressure, fuel present does not mean suffecient.

What he said! Was it mine I'd spray some carb cleaner in it while attempting to start her... If she pops and tries to run I'd look at the fuel pressure.

Ok wooo hooo now tell us how the dist got a tooth off in the first place??? Did YOU do it or did it do it all by itself.. I sure hope YOU did it! If it did it all by itself you really have a problem and I would not start her again till I got her repaired correctly.
