Hello,

If you are not getting power to the fuel pump, it can be due to a faulty fuel pump relay or short in the wiring harness for the fuel pump.
First check the fuel pump relay.
That relay is located under the hood in the power distribution box (fuse block).
See diagram below for the location of the relay.
Visually inspect the relay for corrosion or bunt pin(s).
You can also test the relay as well.

If the relay is good then you will have to check the wiring harness. You could have a short in the wiring.
I have attached the wiring schematics for your reference.

Please let me know of any questions.
Thank you.
