* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery, often under a cover. Check the diagram inside the fuse box cover for the fuel pump relay.
* Under the dashboard: Less common, but possible. Look for a fuse/relay panel under the dash, often near the steering column or on the driver's side.
* In the Body Control Module (BCM): Some later models might incorporate the fuel pump relay function within the BCM, in which case it's not a replaceable relay in the traditional sense.
To find it definitively:
1. Consult your owner's manual: This is the best source. It should have a diagram showing the location of all relays and fuses.
2. Use a wiring diagram: A wiring diagram specific to your year, engine, and trim level will show you the exact location and circuit for the fuel pump relay. You can find these online (often for a fee) through sites specializing in automotive repair information (like Mitchell OnDemand, AllData, etc.).
3. Look for a relay with markings: Even without the diagram, look at the relays in your fuse boxes. Some relays might be clearly labeled (although this isn't always the case).
Caution: Always disconnect the negative battery terminal before working with electrical components in your vehicle to avoid shorts and potential injury.
