I believe that you can switch the Horn Relay with the Fuel Pump Relay and if the horn no longer works and the Fuel Pump does then that relay went bad... try that, its a sure fire way to know whats wrong... If it checks out good it might be a Defective Fuel Pump.

A fuel pump pressure test could determine the condition of the fuel pump and fuel system.
the fuel pump is in the gas tank on all most all fuelinfected cars and trucks, there may be a fuel pump relay somewhere if im correct the filter is integral to the pump and only gets changed if the pump goes bad,if you have a 12 volt test light go to the connector on the fuel pump and see if it lights up when the car is cranking if you have power to the pump then most times its a bad pump,if there is no power then you may have a bad fuse or relay :) Fuel pump is in the gas tank like most other modern cars. The fuel filter is under the car on the passenger side. There is a little trick to getting the fuel line connector to release from the fuel filter. Use the special tool or press a open end wrench against the connector. The Haynes manual explains this fairly well.
