Possible high resistance in the circuit. Try bypassing the relay with a jumper wire and check if your voltage reading at the pump changes. If it does, replace the relay. If it doesn't, make sure you have battery voltage inside the fuse block at the relay terminals. Check resistance between fuse block at relay terminal and fuel pump. Check fuel pump ground.
