Well clearly there is a problem if the fuel pump doesn't run. Some dealers are good, and some couldn't find snow in a blizzard.
I'd be checking the wiring harness/connectors that are on the frame rail under the driver's door. The fuel pump wiring runs through there and corrosion or broken wires can cause stalling and no starts.
