2008 Dodge Charger 2.7 Fuel Pump Relay Location: The Complete Owner's Guide
The bottom line up front: On a 2008 Dodge Charger with the 2.7L V6 engine, the fuel pump relay is located in the Totally Integrated Power Module (TIPM), which sits under the hood on the driver's side near the battery. This relay is part of a numbered layout inside the TIPM fuse box, and it controls the electrical power supply to the electric fuel pump mounted inside the fuel tank. If your Charger cranks but won't start, loses power under load, or stalls suddenly, a faulty fuel pump relay is one of the first components you should check before spending money on a new pump itself.
The 2008 Dodge Charger remains a popular sedan across the United States, and the 2.7L V6 version is one of the most commonly seen on the road today. While the car is known for its bold styling and comfortable ride, the fuel delivery system can cause problems as the vehicle ages. Understanding where the fuel pump relay lives, how it works, and how to test it can save you a trip to the mechanic and a lot of unnecessary diagnostic fees. In this guide, we'll walk you through the exact location, the part numbers, common symptoms of failure, how to test the relay, and what to do when it needs replacement.
Why the Fuel Pump Relay Matters in Your 2008 Dodge Charger 2.7
Before you go hunting for the relay, it helps to understand what it actually does. The fuel pump relay is a small electromagnetic switch that acts as the middleman between the battery and the fuel pump. When you turn your key to the "ON" position, the Powertrain Control Module (PCM) sends a signal to the relay, which then closes its internal contacts and delivers battery voltage to the fuel pump. This pressurizes the fuel rail and gets the system ready for ignition. Once the engine starts, the relay stays energized as long as the engine is running.
If the relay fails, the fuel pump receives no power. That means no fuel pressure, no start, and a car that sits dead in your driveway. A bad relay can also cause intermittent electrical problems—your car might start fine one day and refuse to start the next. Because the relay is easy to access and cheap to replace, it is always smart to verify its condition before you start dropping the fuel tank or replacing the pump itself.
Where Exactly Is the Fuel Pump Relay Located?
The 2008 Dodge Charger 2.7 uses a central power distribution unit called the Totally Integrated Power Module (TIPM). This is the main fuse and relay center for the entire vehicle. It is located under the hood, mounted to the driver's side fender area, close to the battery and the air filter housing. You cannot miss it—it is a large black plastic box with a cover that says "FUSES" or "TIPM" on top.
To access the fuel pump relay, follow these steps:
- Open the hood and secure it properly. Make sure the engine is off and the keys are out of the ignition.
- Locate the TIPM. Look on the driver's side of the engine bay, just behind the headlight and near the battery. The cover is held on by two clips or small screws, depending on the exact build date of your vehicle.
- Remove the cover. Press the tabs or remove the screws, then lift the cover off. You will see a dense array of fuses and relays arranged in rows.
- Identify the fuel pump relay. On the 2.7L engine, the fuel pump relay is typically in the location marked for the fuel pump, often labeled as such on the underside of the TIPM cover. In many 2008 Charger models, the fuel pump relay sits in the cavity that matches the diagram printed on the cover. If the label is faded, check the fuse box diagram in your owner's manual or the printed chart on the underside of the cover.
Different sources point to slightly different cavity numbers depending on the market and options, but on the 2008 Charger 2.7, the fuel pump relay is generally found in one of the front row relay positions within the TIPM. The relay itself is a standard ISO micro relay—small, square, and colored, usually black or gray, with four or five metal prongs coming out of the base.
How to Confirm You Found the Right Relay
There is a simple way to confirm that you have found the fuel pump relay before you remove it. Turn the ignition key to the "ON" position without cranking the engine. You should hear a faint buzzing or whirring sound coming from the rear of the car—that is the fuel pump priming. You can also feel the relay click as it energizes. Place your fingers on the relay while a helper turns the key to the "ON" position. When the relay is working, you will feel a distinct click. If you feel nothing, the relay may not be receiving the control signal, or it may be dead.
Another way to confirm is to swap it with an identical relay in a non-critical circuit, such as the horn relay or the rear window defogger relay. If the car starts after the swap, your original fuel pump relay is bad. This is a widely used trick among DIY mechanics because it costs nothing and takes less than two minutes.
Symptoms of a Failing Fuel Pump Relay in the 2008 Charger 2.7
Recognizing the warning signs early can prevent you from being stranded. Here are the most common symptoms linked to a failing or failed fuel pump relay on the 2008 Dodge Charger 2.7:
-
Engine cranks but will not start. This is the most obvious symptom. The starter motor turns the engine over, but the fuel pump never runs, so the cylinders get no fuel and the engine cannot fire up.
-
Intermittent start failure. The car starts fine for weeks, then suddenly refuses to start. After sitting for a while, it starts again. This intermittent behavior points strongly to a relay with worn contacts or a broken solder joint inside.
-
Engine stalls while driving. The relay can lose contact temporarily while you are on the road, cutting power to the fuel pump and killing the engine. Some drivers report the car restarts after a few minutes once the relay cools down.
-
No fuel pump prime noise. When you turn the key to the "ON" position, you should hear the fuel pump hum for two or three seconds. If there is complete silence from the rear of the car, the relay is likely not closing.
-
Check Engine Light with fuel pressure codes. You may see codes like P0087 (fuel rail pressure too low) or P0191 (fuel pressure sensor range/performance) stored in the PCM. These codes do not always mean the pump is dead—they can also be triggered by a relay that works only part of the time.
How to Test the Fuel Pump Relay at Home
Testing the relay does not require any special tools. With a multimeter and a 12-volt power source, you can verify whether the relay is functional in about ten minutes.
Step 1: Visual inspection. Pull the relay out and look at the prongs. Check for signs of burning, melting, or corrosion. If the plastic housing looks discolored or warped, replace the relay immediately.
Step 2: Check the coil resistance. With a multimeter set to ohms, touch the two coil pins on the relay (typically pins 85 and 86). A good relay shows a resistance reading between 50 and 120 ohms. An infinite reading means the coil is open and the relay is dead.
Step 3: Apply 12 volts. Connect the relay coil pins to a battery or power supply. You should hear a distinct click, which tells you the electromagnet is working. With the relay energized, use the multimeter to check for continuity across the switch pins (typically pins 30 and 87). A good relay shows near-zero resistance. No continuity means the relay cannot pass power, and you need to replace it.
If your relay passes all these tests, the problem lies elsewhere—possibly in the wiring, the PCM, or the fuel pump itself. If the relay fails any test, replacement is the only option.
Common Mistakes and Misconceptions
Many owners assume a no-start condition means the fuel pump is dead. That assumption often leads to unnecessary replacement of a perfectly good pump. On the 2008 Dodge Charger 2.7, the fuel pump is inside the gas tank, and replacing it is a labor-intensive job. Always check the relay first—it is a five-minute job that can save you hundreds of dollars.
Another mistake is using the wrong replacement relay. The 2008 Charger uses a standard ISO micro relay, but not all micro relays are identical. Some have different current ratings. A relay with too low a current rating will overheat and fail quickly. Always choose a replacement that meets or exceeds the original specification.
Some owners also forget to check the fuse associated with the fuel pump circuit. Even if the relay is brand new, a blown fuse will prevent the relay from functioning. Check both the fuel pump fuse and the relay together whenever you suspect a fuel delivery problem.
Step-by-Step Replacement Procedure
When you have confirmed the relay is bad, replacing it is straightforward.
- Turn off the ignition and disconnect the negative battery terminal. This prevents any accidental short circuits while you work.
- Remove the TIPM cover. Use the clips or screws to lift it off and set it aside.
- Pull the old relay straight out. Grasp it firmly and pull upward. Do not wiggle it excessively, as this can bend the prongs.
- Compare the new relay with the old one. Check the part numbers and the pin layout to ensure they match.
- Push the new relay straight down into the cavity. It should seat firmly with a slight click.
- Reinstall the TIPM cover and reconnect the battery.
- Turn the key to the "ON" position and listen for the fuel pump prime. If you hear the buzz from the rear, you have solved the problem.
- Start the engine and let it idle for a few minutes to confirm normal operation.
What If the Relay Is Not the Problem?
If your new relay does not fix the issue, the fault could lie in the wiring harness between the TIPM and the fuel pump, a faulty PCM driver, or a dead fuel pump motor itself. On the 2008 Charger, wiring issues near the rear axle and the fuel tank are not uncommon in high-mileage vehicles. Corrosion and chafed wires can interrupt the ground or power feed even when all components test fine outside the car.
If you have verified the relay, checked the fuse, and confirmed voltage at the relay socket, the next step is to test the fuel pump connector at the tank. This requires lifting the vehicle and accessing the top of the fuel tank. At that point, many owners decide to replace the fuel pump assembly preemptively, given that the pump is already accessible.
