If youre unsure what relay is your fuel pump relay, you use a screw driver to unlock the socket from the fuse box and look at the colors. Get your schematic for your exact year and look for the fuel pump on the schematic. Once found, itll tell you the colors of the fuel pump relay socket, if they dont match, try the other sockets. Once found, you can use a jumper (piece of small length wire with both ends exposed) and jump the leads for power in and power out. This will complete the circuit to your fuel pump. It will activate whether the car is on, off, or even if the key is in the ignition. If it works, the pump is not at fault, If it doesnt, check the fuel pump fuse. If good, go to the pump and hit it lightly with a mallet or rubber hammer, you dont want to damage if its good. If it turns on, then your pump is going out and you need to get a new one.
