Hello,

First item to check if the fuel pump is not turning on is the relay for the pump.
The fuel pump relay is located in the fuse box under the hood.
Do a visual check for any corrosion or burnt pin(s).
You can also test the relay:

If the relay is good, check to see if you are getting power to the fuel pump harness. If you do not have any power to the connector then you have a short in the fuel pump wiring.

If there is power to the connector, then it is likely a bad pump.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
