2009 Dodge Journey Fuel Pump Relay Location: Where to Find It and How to Swap It Yourself
The bottom line up front: On a 2009 Dodge Journey, the fuel pump relay is located inside the engine compartment fuse box (also called the Integrated Power Module or IPM), which sits on the driver’s side near the battery. You don’t need to remove the interior panels or crawl under the rear seat to get to it. In most cases, the relay is a small, square, dark-colored component with five prongs, clearly labeled on the fuse box cover or in the owner’s manual. If your Journey cranks but won’t start, or if the fuel pump stays silent when you turn the key to the ON position, the relay is one of the first things you should check.
This guide walks you through the exact location, how to confirm the relay is bad, and how to replace it in about fifteen minutes with basic hand tools. We’ll also cover common mistakes DIYers make, how to test the relay with a multimeter, and where to buy a quality replacement if you need one.
Where Exactly Is the Fuel Pump Relay on a 2009 Dodge Journey?
The 2009 Dodge Journey uses a centralized fuse and relay box under the hood. Open the hood and look at the driver’s side, close to the battery. That black plastic box with the removable lid is the Integrated Power Module (IPM). Pop the lid off, and you’ll see rows of fuses and relays.
The fuel pump relay is not the only relay in the box, so you need to identify it correctly. Look on the underside of the IPM lid. Chrysler, Dodge’s parent company, prints a diagram listing the function of every fuse and relay. The fuel pump relay is usually labeled “Fuel Pump” or “Fuel Pump Relay.” If the label has worn off, check your owner’s manual. The relay is typically a standard ISO mini relay, which is about one inch square, with five metal blades sticking out of the bottom.
If you can’t read the label at all, you can identify the relay by following the wiring. The fuel pump relay will have one or two thick wires (often dark blue or dark green with a tracer) that trace back to the fuel pump fuse and then to the fuel pump itself. But for most owners, the printed label is enough.
Why Does the Fuel Pump Relay Matter So Much?
The fuel pump relay acts like a switch. When you turn the ignition key to the ON position, the engine computer (PCM) sends a small electrical signal to the relay’s coil. That signal closes the relay’s internal contacts, which then sends full battery voltage to the fuel pump. The pump pressurizes the fuel rail, and the engine is ready to start.
If the relay fails—either the coil burns out or the contacts get pitted from years of arcing—the fuel pump gets no power. The engine will crank over normally but never fire up, because there’s no fuel pressure. A shorted relay can also leave the pump running all the time, which drains the battery and floods the engine with fuel.
On the 2009 Journey, there’s also a fuel pump fuse located in the same IPM. Many people confuse the fuse with the relay, but they’re separate components. The fuse protects the circuit from overload, and the relay does the switching. If you suspect a fuel system electrical problem, check both.
Signs That Your Fuel Pump Relay Is Failing
Here are the most common symptoms drivers report with a bad fuel pump relay on a 2009 Dodge Journey:
1. The engine cranks but won’t start. This is the #1 symptom. You hear the starter motor turning the engine over, but there’s no fuel pressure, so the engine never fires. Turn the key to ON (without cranking) and listen near the rear seat. If you don’t hear the fuel pump hum for a second or two, the relay is a likely culprit.
2. Intermittent stalling. If the relay contacts are worn, they may work when cold but fail when hot. The engine runs fine for a while, then suddenly dies, then restarts after the relay cools down. This can be tricky to diagnose because the relay tests fine when it’s cold.
3. No power to the fuel pump. Connect a test light or multimeter to the fuel pump power wire at the rear of the vehicle. If you have no voltage with the key on, the relay isn’t delivering current.
4. Fuel pump runs constantly. If the relay’s internal contacts are welded shut, the pump never shuts off. You’ll hear it buzzing even with the engine off, and the battery will drain overnight.
5. Check engine light with codes P0231 or P0230. These codes indicate a low voltage or open circuit in the fuel pump secondary circuit. A bad relay can trigger these codes on Dodge vehicles.
How to Test the Fuel Pump Relay (No Special Tools Needed)
Before you buy a new relay, take two minutes to test the one you have. You’ll need either a test light or a digital multimeter. If you don’t have either, you can use a household 12V battery and a piece of wire, but a multimeter is easier and safer.
Step 1: Locate the relay in the IPM and pull it straight out. It’s held in by friction, so a firm tug works. If it’s stuck, use a pair of needle-nose pliers on the sides—don’t pry on the plastic housing.
Step 2: Look at the relay’s base. You’ll see five prongs, usually numbered 30, 85, 86, 87, and 87a. Prongs 85 and 86 are the coil terminals. Prongs 30 and 87 are the switch contacts.
Step 3: Set your multimeter to measure resistance (ohms). Touch the leads to prongs 85 and 86. A good relay coil will read between 50 and 120 ohms. If you read infinite resistance (open), the coil is burned out and the relay is dead.
Step 4: Set the multimeter to continuity mode. Place the leads on prongs 30 and 87. You should hear no beep, meaning the circuit is open. Now apply 12V power to prongs 85 and 86 (you can use a battery or a jumper wire from the car battery). With power applied, prongs 30 and 87 should now beep, meaning the switch has closed. If the relay doesn’t click when you apply power, or if the contacts don’t close, the relay is bad.
How to Replace the Fuel Pump Relay on a 2009 Dodge Journey
Replacing the relay is a five-minute job. Here’s the step-by-step:
1. Turn the ignition off and remove the key.
2. Open the hood and locate the IPM on the driver’s side.
3. Remove the IPM cover. Some covers have a latch; others just snap off. Press the release tabs and lift.
4. Find the fuel pump relay. Use the diagram on the cover or your owner’s manual.
5. Pull the old relay out. It should come out with a firm pull. If it’s corroded or stuck, gently rock it side to side while pulling.
6. Compare the old relay to the new one. They must have the same part number or at least the same pin configuration. Most 2009 Journeys use a standard 5-pin relay, but it’s worth checking.
7. Push the new relay straight in until it seats fully. You should feel a slight click.
8. Reinstall the IPM cover. Make sure it locks in place.
9. Turn the key to ON and listen for the fuel pump. You should hear a brief hum from the rear of the vehicle. If you don’t, recheck the relay orientation and the fuse.
Common Mistakes to Avoid
Mistake 1: Replacing the relay and forgetting to check the fuse. The fuel pump fuse and relay are separate. If the fuse is blown, a new relay won’t help. Check both at the same time.
Mistake 2: Using the wrong relay from a generic parts bin. Relays look alike, but the pin layout and amperage rating vary. A 30A relay can look identical to a 40A relay. Always match the part number or consult the owner’s manual.
Mistake 3: Disconnecting the battery before you pull the relay. You don’t need to, but if you do, make sure you have the radio security code handy. A better approach is to just leave the battery connected but make sure the key is off.
Mistake 4: Assuming the relay is the only problem. If the relay tests good, move on to the fuel pump itself, the inertia switch (if equipped), and the wiring harness. On the 2009 Journey, the fuel pump is accessed through an access panel under the rear seat, but you usually don’t need to go that far for a relay issue.
What If It’s Not the Relay? Quick Next Steps
If a new relay doesn’t fix the problem, work through this checklist:
- Check the fuel pump fuse with a test light. A blown fuse means a short somewhere in the circuit.
- Verify the fuel pump gets power. Probe the harness connector near the fuel pump. No power means the problem is between the relay and the pump.
- Check the ground connection. A poor ground at the fuel pump module will cause the pump to run weak or not at all.
- Listen for the pump. If you hear it humming but the engine still won’t start, the issue could be a clogged fuel filter or a dead pump, not an electrical fault.
Where to Buy a Replacement Fuel Pump Relay
Your local auto parts store carries a generic relay that will work, usually for $10 to $20. Dealerships sell OEM relays at a higher price, but for the 2009 Journey, a quality aftermarket relay is fine. If you want the peace of mind of a brand you can trust, consider looking at relay options or, more importantly, the fuel pump itself if it’s worn out.
