Sounds like the fuel pump died, this is not unusual.
Hopefully it has less than 3/4 tank of fuel in the tank.
Forget about the Voltage readings, this almost always throws everyone. What you are likely measuring is a supervisory Voltage that the DME is sending to the fuel pump. You will only get 12 Volts during cranking or during the 2-3 second prime window. Even then you may miss the 12 Volts depending on how and what you are doing to measure the Voltage.
The fuel pump relay is located behind the glovebox. You need to remove the glovebox door and glovebox liner to access it.
The horn and fuel pump relay are interchangeable if you need to swap them.
Suggest you replace the fuel pump anyway, also order a fuel filter, it does not need to be changed at this moment, but get is changed in the next week or so. I really recommend fuel filters changed every 30k miles based upon all the black scum about 90% of these filters have in them when cutting them open for inspection.
