Great, now you have air in the fuel system....
I have no idea but you should go to the Chev Truck forums. Lots of people there who have lot of experience with Chev Trucks. I always use the vehicle forums when I have problems and they are great.

It sounds like the pump still. I used to work at a G.M. store and we have seen bad pumps out of the box. There is actually a valve in those modules.
