Hello,

When you turn the key to on position, can you hear the fuel pump kick on?

If you don't hear the pump it could be the pump or the relay.
First check the fuel pump relay. The relay is located under the hood in the junction box.
Check to see if there are any burn pins on the relay.
You can also test the relay:

I have attached the fuel pump replacement diagrams for your reference.

Please let me know of any questions.

Thank you.
