you will have to eliminate the line by checking fuel pressure - take it off at both ends and blow it out if the pressure is low. sometimes you get a bad part, was the pump new or rebuilt?

simplest way to check fuel pump operation is by either listening for the humming sound it makes (with the gas cap off) or by putting your hand on the gas tank (to feel the vibration as the pump runs), and having an assistant to turn the ignition switch on (do not start engine). The pump should run for about 2 seconds and the stop (it will run for 2 secs each time you turn the key on, unless the engine starts and then the pump continues to run).
If there is evidence that the pump is working, this eliminates the need to check the fuses and/or relays.

Double check the flow direction of the fuel filter you installed. Reverse installation can lower fuel pressure.

Disconnect the fuel line at the fuel rail, underhood. Place the end of the fuel line in a bottle, turn the ignition switch on for about 5 seconds (do not spin the engine over). For the 2 seconds that the fuel pump runs it should pump about 3-4 ounces of fuel into the bottle. If it's significantly less, suspect a clogged line.
