you could put a fuel pressure guage on it, with the engine shut down check for fuel pressure bleed down. You may have one or more injectors leaking down into the cylinders causing it to basically flood out.
If you got good spark, and it cranks but dont start yoou could also pull a plug/plugs and smell them for fuel.

Starting with pedal to the floor, makes it start in so-called Clear Flood Mode, in which the injectors are shut...could be a clue towards leaking injectors. Or a subpar TPS...

IF you're planning to eventually upgrade, you might as well look into that now. But first I would just check things, before you Gung Ho with all kinds of new parts..

Thanks for all the ideas guys
This is a great forum. I am planning on borrowing a fuel pressure gage from an auto parts store either today or tomorrow when I get time.
What are the specs for pressure?
I do not have an owners manual, and my Haynes manual is in the mail.
