Does the fuel pump run, when you turn the key to the on position? Can you hear the fuel pump? Your spider injection assembly probably is leaking and would need to be replaced. This is a common problem with those year Vortec engines. The new spider injection assembly has ben upgraded.

Yep that or the fuel pressure regulator is stuck in bypass.
