I would start by testing at the relay for power. Connect a test light to the pump side of the relay and have someone turn the key to "on". The relay should have power for a few seconds before it turns back off. If you have power there, then connect the test light to the terminal/ wire at the pump and check it again. The test light should come on for a few seconds and then cycle off. You should also be able to hear the pump run for a few seconds when you turn the key to "on" as well. If you have power and the pump runs, disconnect the fuel line after the filter, unhook the wire to the pump and connect an external 12 volt source to the pump and check your fuel flow. Use a short hose and run the fuel into a clean container for re-use and let it run for a while to see if the pump stops or flow is low. You may also want to check the wire size going to the pump and check for amp drop. That will cause the pump not to work as well. If all works well, connect a fuel test gauge to the fuel rail to make sure you have adequate pressure at the rail.
