2012 Dodge Journey Fuel Pump Relay Location: The Complete Owner's Guide

The bottom line up front: On a 2012 Dodge Journey, the fuel pump relay is located inside the Totally Integrated Power Module (TIPM), which is the main fuse box mounted in the engine compartment near the battery. The TIPM sits on the driver's side of the engine bay, and the fuel pump relay is built directly into the TIPM's circuit board rather than being a standalone plug-in relay you can swap out like a traditional fuse. This is a critical distinction because it affects how you diagnose and fix the problem .

Why This Location Matters More Than You Think

Your 2012 Journey's fuel pump relay acts as an electrical switch that controls power delivery to the fuel pump. When you turn the ignition key, the relay receives a signal from the Powertrain Control Module (PCM) and sends battery voltage to the fuel pump, pressurizing the fuel system so the engine can start .

The fuel pump relay on your Journey is not a simple plug-in component like those found on older vehicles. Instead, it is soldered directly onto a circuit board inside the TIPM . This integrated design is the root cause of many fuel delivery problems on Chrysler, Dodge, Jeep, and Ram vehicles from this era. The relay is subject to heat stress, electrical surges, and corrosion over time. When it fails, you cannot simply pull it out and replace it with a standard relay from an auto parts store .

Understanding this location saves you time and frustration. If you go looking for a small, cube-shaped relay under the hood thinking you can pop it out and replace it in five minutes, you will not find one. The relay is inside the TIPM, and your repair options are different from what you might expect .

How to Find the TIPM on Your 2012 Dodge Journey

Locating the TIPM is straightforward and takes less than a minute:

  1. Open the hood and secure it properly. Stand on the driver's side of the vehicle facing the engine bay.
  2. Look for a black plastic box near the battery. The TIPM sits on the driver's side of the engine compartment, close to the battery and the strut tower. It has a removable lid held by locking tabs.
  3. Press the tabs and lift the lid off. The underside of the lid typically has a diagram printed on it that identifies each fuse and relay cavity. This diagram helps you locate the fuel pump fuse and related components, even though the relay itself is sealed inside the TIPM.

Important: The fuel pump relay is not located inside the vehicle, under the dashboard, or near the fuel tank. It is always within that under-hood fuse box for this generation of Dodge vehicles . However, because the relay is integrated into the TIPM's circuit board, you will not see a separate relay labeled "Fuel Pump" that you can pull out by hand .

Symptoms of a Failing Fuel Pump Relay

Recognizing the signs early can save you from being stranded on the side of the road. Watch for these common symptoms, which are frequently reported by 2012 Dodge Journey owners and mechanics:

  1. Engine cranks but won't start. This is the most common symptom. You hear the starter motor turning the engine over, but the engine never fires up because no fuel is reaching the injectors .

  2. No fuel pump priming noise. When you turn the key to the "ON" position (before cranking), you should hear a quiet whirring sound from the rear of the vehicle for about 2 to 3 seconds as the fuel pump pressurizes the system. If you do not hear this sound, the relay is likely not sending power to the pump .

  3. Intermittent starting issues. The vehicle may start fine for days, then suddenly refuse to start. This is a classic sign of a failing relay that is working intermittently .

  4. Engine stalls while driving. If the relay cuts out while the engine is running, the engine will stall without warning. This can be dangerous, especially in traffic .

  5. Battery drain. In some cases, a failed relay can stay stuck in the "closed" position, keeping the fuel pump running even when the vehicle is turned off. This will drain your battery overnight .

  6. Sputtering at highway speeds. A relay with worn contacts may not carry full current, causing the fuel pump to run at reduced capacity. This leads to sputtering or loss of power when you accelerate or climb hills .

  7. Long cranking time before firing. The fuel system takes extra seconds to build pressure because the relay is not sending full power to the pump .

Any one of these symptoms warrants immediate attention. Driving with a failing relay risks getting stranded, and a dead relay can also damage the fuel pump itself by cycling it under low voltage .

How to Diagnose the Fuel Pump Relay Problem

Before you spend money on parts, take a few minutes to confirm the fuel pump relay is actually the issue. Here are the steps you can follow at home with basic tools:

Step 1: Listen for the fuel pump. Turn the key to the "ON" position and listen near the rear of the vehicle. If you hear no sound for 2 to 3 seconds, the pump is not getting power .

Step 2: Check for power at the fuel pump fuse. The TIPM has a diagram on the underside of the cover. Locate the fuel pump fuse, often labeled "FP" or "Fuel Pump." Use a test light to see if there is power at the fuse terminals when the key is turned to "ON." If there is no power, the relay inside the TIPM is likely bad .

Step 3: Check the fuel pressure. If you have a fuel pressure gauge, connect it to the fuel rail test port on the engine. Turn the key to "ON." You should see pressure rise to around 55 to 60 psi for a few seconds . If the pressure stays at zero, the pump is not running.

Step 4: Use a fused jumper wire for testing only. As a diagnostic step, you can use a fused jumper wire to bypass the relay. This is a temporary test only. Identify the power supply and fuel pump terminals in the relay socket, referring to a wiring diagram for your specific vehicle. Connect them with a fused jumper wire. If the vehicle starts and runs, the relay is definitely the problem. Do not leave the jumper wire in place permanently because it bypasses all safety features and can be dangerous .

Your Repair Options for the Fuel Pump Relay

Once you have confirmed the relay is faulty, you have several options. They range from the most affordable to the most expensive:

Option 1: Install an External Fuel Pump Relay Bypass Kit ($50 to $150)

This is the most popular and cost-effective solution for DIY owners. The bypass kit installs a new, independent relay outside the TIPM that takes over the job of the failed internal relay. You do not need to replace or reprogram the TIPM .

What you need:

  • A standard automotive relay (30/40A, SPDT or SPST)
  • A relay socket with wiring leads
  • An inline fuse holder with a 15A or 20A fuse
  • 14 to 16 gauge wire
  • Wire strippers, crimpers, electrical tape or heat shrink
  • A multimeter or test light

Basic installation steps:

  1. Disconnect the negative battery terminal.
  2. Locate the TIPM in the engine compartment and identify the fuel pump power wire and trigger wire. Use a wiring diagram specific to your Journey.
  3. Connect the new relay's coil to the trigger wire. This wire carries 12V+ when the ignition is on.
  4. Connect the new relay's power contacts to a constant 12V source (battery) through the inline fuse.
  5. Connect the output of the new relay to the fuel pump power wire.
  6. Ground the relay properly.
  7. Reconnect the battery and test. Start the vehicle and confirm the fuel pump runs .

Option 2: Use a Temporary Bypass Cable Using Fuse Taps ($25 to $35)

This is the quickest way to get your vehicle running again, but it should only be used as a temporary fix. The bypass cable takes power from an alternate fuse slot (M37 or F90) and feeds it directly to the fuel pump fuse slot (M25 or F70), bypassing the faulty relay .

What you need:

  • Two 20 amp ATM fuse taps (micro2 or mini-blade, depending on your TIPM style)
  • One 20 amp fuse (for the M37 side)
  • Wire connectors or butt connectors
  • Heat shrink tubing or electrical tape

Important warnings for this method:

  • Do not use this as a permanent fix. The fuse tap connections can become loose over time, and bad connections have been known to cause fires .
  • Only use the M37 slot for bypass mode because it only powers the fuel pump when the engine is running or being started. The F90 slot leaves the fuel pump running when the engine is off .
  • Monitor the cable for heat. If the wire feels hot to the touch, the cable or connections may be overloaded .
  • Remote start may not work with this cable installed .

Option 3: Replace the TIPM ($800 to $1,500 or more)

This is the most expensive option and is often recommended by dealerships. The TIPM is a central electrical control unit that manages power distribution for many systems. Replacing it involves removing the old unit, installing a new one, and having it programmed to match your vehicle. This is a significant expense, and for many owners, the external relay bypass kit is a more practical solution .

What About the Fuel Pump Itself?

The fuel pump relay and the fuel pump work together. A relay failure can mimic a pump failure, and vice versa . The fuel pump on a 2012 Dodge Journey is mounted inside the fuel tank, and replacement typically costs between $350 and $700 including parts and labor, depending on your location and whether you choose an OEM or aftermarket unit .

The 2012 Dodge Journey requires a fuel pressure of roughly 55 to 60 psi at the fuel rail for the engine to run properly. When the pump starts to fail, it cannot maintain that pressure, which leads to a variety of driveability problems .

Common symptoms of a failing fuel pump include:

  • Hard starting or no start
  • Engine sputtering or hesitation at speed
  • Loss of power under load
  • Engine surging
  • Check engine light with codes like P0087 (Fuel Rail/System Pressure Too Low) or P0191 (Fuel Rail Pressure Sensor Range/Performance)

Important caveat: These symptoms can also be caused by a clogged fuel filter, a faulty fuel pump relay, a bad fuel pressure regulator, or even a vacuum leak. Before you condemn the pump, it is worth doing a proper fuel pressure test at the service port on the fuel rail .
