Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

THE FUEL PUMP IS BAD.
if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.
and i doubt that you are seeing enough fuel pressure to run a vortec engine.
low fuel pressure equals a non running vortec
