However, the most common locations are:
* Under the hood, in the Power Distribution Center (PDC): This is the most likely spot. The PDC is usually a large fuse and relay box located somewhere near the battery, often on the driver's side fender well. Look for a box with numerous fuses and relays. The fuel pump relay will often be labeled, or you can consult your owner's manual or a wiring diagram to find the correct relay.
* Under the dash: While less common for the fuel pump relay specifically on a '92, some Jeep models did place certain relays under the dash. Check your owner's manual.
To find it:
1. Consult your owner's manual: This is the best place to start. The manual will show you the exact location of the PDC and often include a diagram of the relays within it.
2. Use a wiring diagram: A wiring diagram specific to your 1992 Jeep Wrangler (including engine size) will show you the exact location and identify the fuel pump relay. You can find these diagrams online (often for a fee) or at an auto parts store.
3. Look in the Power Distribution Center (PDC): If your owner's manual doesn't specify, carefully inspect all the relays in the PDC. Some relays might be labeled, while others might require tracing wires or using a multimeter to identify the fuel pump relay.
4. Check online forums: Search online Jeep forums for your specific year, model, and engine. Other Wrangler owners may have already posted about their fuel pump relay location.
Remember to disconnect the negative battery terminal before working with any electrical components. Also, be cautious when working near the battery as it can produce corrosive gases.
