You need to check the fuel pump pressure at the fuel rail. If the car starts with ether, then you are getting spark. That means you aren't getting fuel. Check to see if the pressure at the rail is within spec and if it is, check to see if the injectors are getting power.

You now need to check to see if there is power to the fuel pump. Before doing that, switch the fuel pump relay with another relay with the same part number. Let me know what you find.

The relay was changed before the fuel pump. If the old pump was bad, could that have caused the relay to go out

All of the afore mentioned has been done after replacing the fuel pump. What about filter? And how do I check for power to the fuel pump

Chances are the relay is fine. You need to remove the fuel tank and check for power at the wiring harness for the fuel pump. Before doing that, just try another relay. It is much easier to do and that COULD be the problem, but chances are it is fine.
