if you are used to hearing the fuel pump but cannpt hear it anymore, it's probably a fuse or the pump. Pump replacement is expensive, so always make sure the pump is getting voltage before replacing.

if im correct there should be a red wire on the drivers side of the firewall not connected to anything. take a jumper wire to the positive side of the batt. and connect it to the red wire. if you can hear the fuel pump, there is a short somewhere. it could be as simple as the inertia switch or emergency shut-off switch. check the fuel pump relay too
SOURCE: wanted to no if there
GM does not have a reset button to reset the fuel system. The only manufacturer that I am aware of that does this is Ford. If the pump doesn't work than the first thing I would do is check for power at the pump. There should be two gray wires at the connector. The bigger one is power to the pump. If there is no power than check fuse and relays.

SOURCE: where is the fuel pump
It is located in the fuel tank. The fuel tank will need to be removed from the vehicle in order to replace the pump.
