I'm going to assume that you have voltage at he fuse block & voltage to the relay.

If voltage is present at both be sure to check the connector at the pump,

voltage can get lost at the connectors (barrels) due to grime or backprobing.

Be sure to test the ground circuit as well..

hopes this helps,
