You need to test the fuel pressure with a special gauge, the pressure should be greater then 35PSI. The Vortec set up has more to it but what you seem to be discribing is a faulty fuel pump. Im assuming that the fuel filter was changed too. But you need to have a special tool that will allow you to isolate the fuel flow from the tank to the engine. popular reasons for fuel system failiers are filter, pump, fuel pressure reg. valve(located underneath the plenum) and not common but maybe fuel pump relay.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

After you dump the fuel in the throttle body it will continue to run on its own or die as soon as it burns up all the fuel you dump in? Do you have access to (Noid lights)? Are both plugs attached to the distributor?

The last pieces in the chain are the fuel regulator and the injectors. The regulator is inside the throttle body, but it sounds that maybe the injectors are not firing. For nothing else, check out the connections to the injectors. Possibly they are clogged. Try a few treatments of injector cleaner.
