You'll need to consult your owner's manual. This is the best resource to find the relay's location.
If you don't have the owner's manual, your best bet is to:
* Check the fuse box under the hood: This is the most common location for relays. Many Stanzas have a fuse box under the hood near the battery. The relays are usually in a separate compartment or on a panel within the fuse box. Look for a diagram on the inside of the fuse box cover – it *may* identify the fuel pump relay.
* Check the fuse box inside the car (if applicable): Some models have an additional fuse/relay box inside the cabin, often under the dashboard.
* Use a wiring diagram: A wiring diagram specific to your 1988 Nissan Stanza is the most definitive way to locate the fuel pump relay. You can often find these diagrams online through automotive repair websites or forums specializing in Nissan vehicles.
Important Note: Before working with any electrical components, disconnect the negative terminal of your car battery to prevent accidental shorts or damage. If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic.
