Hello,
Since you are not getting power to the pump, it likely has a short in that harness.
You will have to trace the fuel pump wires to find that short.
Here is a helpful article on how to test wiring harness:

I have attached the fuel pump wiring schematics for your reference.
Please let me know of any questions.
Thank you.
