Id remove filter from line that runs on frame rail and set filter in bucket and turn key to run position if fuel comes thru filter maybe fuel rails plugged. If it does not come out either pumps not working or its not getting power.

Rock Autos deff cheaper on parts but certain things you buy local in case issues like this arise . Its easier to run down the street than return via mail and wait.
