Introduction
The Dodge Durango, a powerhouse in the SUV market, combines robust performance with family-friendly features. Known for its striking design, comfortable interior, and powerful engine options, the Durango has carved a niche for itself as a versatile vehicle. However, even the most dependable vehicles require maintenance, and understanding the intricacies of their components is crucial for keeping them running smoothly. One such critical component is the fuel pump, responsible for delivering gasoline to the engine. The fuel pump’s operation is controlled by a small but essential piece of hardware: the fuel pump relay. This guide focuses on a key aspect of Durango maintenance – pinpointing the location of the 2017 Dodge Durango Fuel Pump Relay, empowering owners with the knowledge to address potential fuel system issues.
The fuel pump is, at its core, an engine’s lifeline. It draws fuel from the tank and ensures a consistent supply to the engine, allowing for combustion and, therefore, power. Without a functioning fuel pump, the engine simply won’t start, leaving you stranded. The fuel pump relay acts as an electrical switch, controlling the flow of power to the fuel pump. When the engine is started, the relay activates, sending electricity to the fuel pump, which in turn starts pumping fuel.
Problems with the fuel pump relay can often mimic fuel pump failure. A faulty relay can prevent the fuel pump from receiving power, leading to starting problems, engine sputtering, or stalling. Identifying the location of the fuel pump relay is the initial step in diagnosing and resolving these issues. This article aims to provide a clear, step-by-step guide for locating and, if necessary, replacing the fuel pump relay in your 2017 Dodge Durango, allowing you to regain control and get back on the road.
Understanding the Fuel Pump Relay’s Function
The fuel pump relay, a seemingly insignificant component, plays a vital role in the operational efficiency of your Durango. Think of it as the gatekeeper for the power supplied to your fuel pump. It opens and closes, controlling the electrical current flow. This on/off functionality is crucial. If the relay fails to close when the engine is cranked, the fuel pump won’t receive power, and the engine will likely refuse to start.
The symptoms of a failing fuel pump relay can be varied, and often mimic those of a failing fuel pump. The most common indications include:
- Engine Won’t Start: This is a primary and often frustrating symptom. When you turn the key, you may hear the starter motor crank, but the engine will not fire.
- Engine Cranks but Doesn’t Run: Similar to the first symptom, the engine will crank, but the lack of fuel supply prevents it from starting or running.
- Sputtering or Hesitation: As the relay begins to fail intermittently, the fuel pump may not receive consistent power, resulting in engine sputtering or hesitation, especially under acceleration.
- Stalling: The engine may run for a short period and then stall, particularly at idle, because of the inconsistent fuel supply.
- Sudden Loss of Power: The vehicle may lose power suddenly while driving, signaling a sudden fuel supply interruption.
Fortunately, the fuel pump relay is often a relatively inexpensive part to replace. It’s also a much less complex repair than replacing the entire fuel pump itself. Diagnosing the relay early can potentially save you time, money, and the frustration of dealing with a non-functioning vehicle. This underscores the importance of understanding the location of the 2017 Dodge Durango Fuel Pump Relay, and being able to troubleshoot potential issues.
Safety First: Essential Precautions
Before you embark on any electrical work on your Durango, safety should be your utmost priority. Always take the following precautions:
- Disconnect the Negative Battery Terminal: This is the golden rule of electrical work on vehicles. Disconnecting the negative battery terminal (the black cable) prevents any accidental shorts and protects you from potential electrical shock. Use a wrench to loosen the nut securing the cable to the battery terminal and carefully remove it. Ensure the cable is positioned so that it cannot accidentally touch the battery terminal.
- Work in a Well-Ventilated Area: Gasoline fumes can accumulate and become a fire hazard. Work in a well-ventilated space, preferably outdoors or in a garage with good airflow.
- Avoid Sparks and Open Flames: Refrain from smoking or using any open flames near the vehicle. The presence of gasoline vapors makes the area highly flammable.
- Wear Appropriate Safety Gear: While working with relays, safety glasses aren’t typically necessary, but always wear safety glasses, especially if you work under the car. It is recommended to wear work gloves for some grip when doing the work.
- Take Your Time: Don’t rush the process. Working carefully and deliberately will help prevent mistakes and ensure a successful outcome.
Following these safety precautions will help ensure a safe and efficient experience when attempting to locate and/or replace the 2017 Dodge Durango Fuel Pump Relay.
Finding the Relay: Under the Hood
The primary location for the fuel pump relay on the 2017 Dodge Durango is within the engine compartment’s fuse box. This is generally the most common location. The fuse box may be located near the battery or on the driver’s side of the engine bay, near the fender. Identifying the exact location is the first step.
Locating the Fuse Box
- Open the hood of your Durango. The fuse box is usually a black plastic box.
- Locate the box.
- The cover is usually a snap-on type and may have a small latch or tabs to open. Some boxes might require the use of a flat-head screwdriver to pry open the cover.
- Carefully remove the cover. Many covers have a diagram or label inside, or on the fuse box itself, outlining the location of the fuses and relays.
Identifying the Fuel Pump Relay
- Once you have the cover off, examine the fuse box layout. The interior of the cover or the fuse box itself should have a legend printed on it, indicating the function of each fuse and relay.
- Look for a relay labeled “Fuel Pump” or “FP”. This label will confirm that you have identified the correct relay.
- The specific location of the fuel pump relay may vary slightly depending on the trim level of your 2017 Durango. Consult your owner’s manual for a precise diagram, which typically includes a visual layout of the fuse box and the location of each relay. The relay will have a corresponding number next to its location on the chart.
- Visual Inspection: Fuel pump relays are typically rectangular or cube-shaped. They usually have four or five prongs that plug into the socket in the fuse box. Their colour may vary, but often the colour is black or dark grey. Compare the relay to the diagram you are looking at to verify.
Tools for the Job
You may or may not need specialized tools for this part of the process. Many fuse boxes are equipped with a fuse puller. If not, using a small pair of needle-nose pliers or a relay puller tool will help you remove the relay without damaging it.
Optional Location: Inside the Cabin
Sometimes, the fuel pump relay, or one related to the fuel pump system, might be located inside a fuse box within the cabin of the Durango. This isn’t as common as the under-hood location, but it’s worth checking if the under-hood location is not the source of the problem.
If you suspect the issue might be related to a fuse box inside the cabin, follow these steps:
Locating the Interior Fuse Box
Many Durangos have an interior fuse box located inside the cabin. The location of this interior fuse box can vary. It is often located either on the passenger side footwell, or possibly in the dashboard. Consult your owner’s manual to pinpoint its exact position in your vehicle.
Open the Fuse Box Cover
Once you’ve found the fuse box, carefully open the cover. There might be small latches or screws to remove. Be gentle to avoid breaking the cover.
Examine the Fuse Box Layout
The interior fuse box will also have a diagram that labels the location of fuses and relays.
Identifying the Fuel Pump Relay
Look for a relay labelled “Fuel Pump” or another relevant description to confirm its function. The same visual characteristics of size and shape apply as described for the engine compartment fuse box. Again, cross-reference the layout with your owner’s manual.
It is unlikely the fuel pump relay is found in this location, but it’s good to check the location, in case.
Removing and Replacing the Fuel Pump Relay
Once you’ve located the fuel pump relay in the engine compartment fuse box, the next step is to replace it. If the relay is suspected to be faulty (based on symptoms and testing), here is a straightforward procedure:
Extraction
Use your fingers or a suitable tool (such as needle-nose pliers or a relay puller) to gently pull the relay straight out of its socket. Be cautious, because forcing it could damage the socket and surrounding components. Pull the relay straight up, or out, from its position.
Inspect the Relay
Examine the removed relay carefully. Look for any signs of damage, such as:
- Burnt Contacts: Darkening, pitting, or corrosion on the metal contacts within the relay are a sign of electrical arcing, and a faulty relay.
- Melted Plastic: Any melting or deformation of the relay’s plastic casing is a clear indicator of overheating and failure.
- Loose or Damaged Pins: Check that all the pins are intact and straight.
Obtain a Replacement
Purchase a replacement fuel pump relay. You can buy one at your local auto parts store, a dealership, or online. It’s crucial to get a relay with the same specifications as the original. The part number is often printed on the side of the relay itself. You can either get an Original Equipment Manufacturer (OEM) part, or you can opt for an aftermarket alternative. Either option should work, assuming the part specs match the original part specs.
Installation
Insert the new relay into the socket, ensuring it is properly aligned. Press the relay firmly until it clicks into place. Make sure it is secure.
Double Check
Verify that the relay is completely seated in its socket.
Testing and Verification: Ensuring the Repair
After replacing the fuel pump relay, the next step is to test and confirm that the repair has been successful.
Reconnect Power
Reconnect the negative battery terminal, which you disconnected for safety before starting the work. Tighten the nut securing the cable to the battery terminal.
Crank the Engine
Start the engine and listen carefully. The engine should now start smoothly. It’s not uncommon to hear the fuel pump briefly prime as you turn the key – a humming sound that lasts for a few seconds before the engine starts.
Engine Performance
Pay attention to the engine’s performance. It should idle smoothly, accelerate without hesitation, and run normally.
Troubleshooting
If the engine still doesn’t start or runs poorly after the new relay has been installed, double-check the following:
- Fuses: Inspect the fuses in the fuse box, especially those related to the fuel pump. A blown fuse may have contributed to the problem, or a new fuse might blow as a result of an existing short.
- Connections: Ensure that the new relay is properly seated and making good contact with the socket. Verify that all connectors are secure.
- Fuel Pump Itself: In rare cases, the fuel pump relay replacement doesn’t solve the problem, meaning the fuel pump might need replacing.
- Wiring Harness: Inspect the wiring harness for any signs of damage or shorts.
