Trying to locate the fuel pump relay to see if that’s the issue or the fuel pump is the issue.

Hi,

The fuel pump relay is located in the central junction box on the inside of the vehicle. I attached a pic below and highlighted the relay.

As far as the fuel question is concerned, there are other factors to consider. For example, the vehicle has an inertia switch that will cut power to the pump if it needs reset or fails. Additionally, fuses can do the same.

Here is a link that you may find helpful. It explains how to test a relay and the relay circuit.

Let me know if this helps.
