Check the fuel pump fuse. Often, it's not the pump itself that fails to function, but the power that supplies it. Check in your owner's manual for the location of the fuse box, then find the fuse that corresponds to the fuel pump. Pull it out and inspect it for signs of failure.

Why did my fuel pump go out?
The top reasons for fuel pump failure are contamination, overheating, and the gears in the the fuel pump wearing out over time.
