Lift up the carpet in your vehicle's trunk, here you'll find the battery and the rear fuse panel. This relay all the way at the end, closest to the back of the vehicle on the right, is our fuel pump relay. We'll remove that and go back up to the driver's seat of our vehicle. With the fuel pump relay disconnected, we'll turn the key, run the vehicle until it dies. Then we'll shut it off and crank it a few more times just to ensure that there's no more fuel getting through the injectors. Now that we know there's no fuel pressure left in the system, we can safely work on it.

Once your fuel system is put back together and you're ready to run the vehicle, reinstall your fuel pump relay. Once you've reinstalled the relay, put the back of the cover back on first, snap the front end, set your trunk carpet down. Now we'll turn the key to the on position until we can hear the fuel pump shut off, turn the key off, and repeat that process three times before starting our vehicle. Now our vehicle's good to go.
