Great, I'm also going to rule out the pump itself (although I'm not going to rule out that it's receiving inadequate voltage while cranking). My logic behind this is that it feeds the car at WOT with no issues.

I'm also going to check for a strong blue spark while cranking the cold engine (plugs on the valve cover) and some starting fluid through the pcv hose into the manifold to confirm that it is indeed a fuel issue.

After that I think I'll have a better idea of the direction I need to go. Any other tests or ideas you guys can think of please let me know.
