Finding the fuel pump relay in your 2017 Dodge Durango is crucial for troubleshooting fuel delivery problems. A faulty relay can prevent your vehicle from starting or running smoothly, leaving you stranded. This guide provides a detailed, step-by-step process to locate this essential component. We'll cover various scenarios and offer helpful tips to make the process easier.
Understanding the Fuel Pump Relay's Role
Before diving into the location, let's understand the fuel pump relay's function. The fuel pump relay acts as a switch, controlling the power flow to the fuel pump. When the ignition is turned on, the relay receives a signal and activates, sending power to the pump. This ensures the pump only runs when needed, saving energy and preventing unnecessary wear and tear. A malfunctioning relay can interrupt this crucial power flow, leading to starting issues or a complete inability to start the vehicle.
Locating the Power Distribution Center (PDC)
The fuel pump relay for your 2017 Dodge Durango is housed within the Power Distribution Center (PDC), also sometimes referred to as the fuse box or relay center. This central hub contains various fuses and relays controlling different electrical systems in your vehicle. The exact location of your PDC will depend on the trim level and specific model year of your Durango, but it's generally found under the hood.
Tip: Consult your owner's manual for the precise location and a diagram of your PDC. This manual will be your best resource for specific component locations.
Identifying the Fuel Pump Relay
Once you've located the PDC, you'll need to identify the fuel pump relay itself. This can be tricky as the PDC contains numerous relays, all looking fairly similar. Again, your owner's manual is invaluable here. It should contain a relay diagram showing the location of the fuel pump relay and its corresponding number or symbol.
- Visual Inspection: Many relays are labeled with their function. Look for a label that indicates "fuel pump," "EFI" (Electronic Fuel Injection), or a similar designation.
- Relay Diagram: Refer to your owner's manual's relay diagram. This diagram will match the relay numbers to specific functions.
- Online Resources: Several online forums and repair manuals provide diagrams and pictures specific to the 2017 Dodge Durango. Search online for "2017 Dodge Durango fuel pump relay diagram" to find helpful visuals.
Accessing the Fuel Pump Relay
Accessing the relay may involve removing a cover on the PDC or simply pulling out the relay. Be gentle and avoid damaging any connectors. Consult your owner's manual for the specific procedure to access the relays. Many times there is a small cover that snaps or clips off, allowing you to access all the relays and fuses.
Important Note: Before working on any electrical component, always disconnect the negative terminal of your vehicle's battery. This will prevent accidental shorts and protect you from electrical shock.
Testing the Fuel Pump Relay (Optional)
Once you've located the relay, you can test it using a multimeter or a test light. This step is optional but can help confirm if the relay is indeed faulty. Again, your owner's manual or online resources can guide you through the proper testing procedure.
Replacing the Fuel Pump Relay
If the relay is faulty, replacing it is a straightforward process. Purchase a new relay from a parts store, ensuring you get the correct amperage and type. This information will be on your old relay or in your owner's manual. Simply remove the old relay and plug the new one into its place, ensuring it is securely seated.
Troubleshooting Further Issues
If replacing the relay doesn't solve your fuel delivery problem, the issue might lie elsewhere in the fuel system. Possible causes could include a faulty fuel pump itself, issues with the fuel lines or filter, or even problems with the vehicle's computer system (PCM). Further diagnosis by a professional mechanic may be needed.
Conclusion
Locating the 2017 Dodge Durango fuel pump relay can seem daunting, but with careful attention to detail and the help of your owner's manual, the process becomes manageable. Remember to always prioritize safety and consult professional help if you're unsure about any step of the process. By understanding the role of the relay and following these steps, you can effectively troubleshoot and resolve fuel delivery problems, keeping your 2017 Dodge Durango running smoothly.
