However, it's not always clearly labeled. You'll need to consult your owner's manual or a wiring diagram to identify the specific relay. The relay itself might be unmarked or only have a number. The diagram will show the relay's position within the PDC and often indicate which circuits it controls.
You'll likely find the relay by tracing the fuel pump wiring from the pump itself up to the PDC. Be very careful when working around the PDC, and disconnect the negative battery terminal before starting any work to prevent shorts.
