'86 GT Coupe fuel problem

[Allan Jones <ampj@tiac.net>]

I forgot in my last e-mail to tell all what happens whan I try to
start the car. If I HOLD the key turned all the way over to the starter
position(or the position tried embarrassingly while your engine is
idling) and keep the gas pedal floored, the engine stays running, but
dies instantly when I let go of either the gas or the starter.  Does
that help anybody help me diagnose my problem? I'm fairly sure it's not
helping my engine or starter!
                                Thanx,
                                        Allan
