you have a control issue with the relay. it is controlled by the pcm. now, dont run out and replace this. you need to find out why it is not turning it on.

did you cross the cables trying to start this??

were there any issues prior to this failure??

from here, we cannot see what the issue is. you need to have someone with a scan tool check this to see if the relay is being commanded to turn on the fuel pump. you will need a shop to help you out here.
