Yeah I think it's on the left as you look forward, a quick way to check it is to swap the two outer relays the fan on right fuel pump on left. Middle is the ECU if I remember right. Lets us know if that does not fix it. I think that fuel pump relay may be shared w/the head lamps so if they don't work it's bad.
