Congratulations, Paul!

    It brings back memories of my first engine start back more than a few
years ago.  Your leaking injector does sound like its associated with the
wiring and not the injectors.  Not familiar with your EFI system, but most
of them turn on the injector by grounding one  lead of an injector through a
transistor.  So I would check with an ohm meter each pin of that suspect
injector connector and see if one of them is grounded.  Check the "good"
connector to verify that neither side is grounded.
