Hello,

When then fuel pump relay clicks on/off can you hear the electric fuel pump running?
The relay is located behind the right kick panel at the bottom of the A-pillar, see image 1 below
There should be a light buzzing/humming sound from the rear of your vehicle

The fuel pump is located inside your fuel tank.
See image 2+3 below

To access the fuel pump connectors, you will need to remove the rear seat.
Once you have access to the fuel pump you can test the 12V supply to pump.
There are 2 wires for the fuel pump, 12V feed is on the red/blue wire and the brown wire carries the ground.

The easiest way to test 12V supply would be using a test light. Use the brown wire as the ground and then probe the red/blue wire. Cycle the ignition and when the fuel pump relay clicks in the test light should light up.

How to use a test light.

Please let us know how you get along.

Cheers, Boris
