Replacing Fuel Pump In 2005 Dodge Durango: Step-By-Step Guide

If you're looking to replace the fuel pump on your 2005 Dodge Durango, you'll first need to locate the fuel pump. In vehicles today, the fuel pump is usually mounted inside the fuel tank, so you'll need to remove the fuel tank to access it. There is no access panel, so you'll need to use a floor jack to support the plate and then remove the bolts using a gear wrench or ratchet with a swivel socket and extensions.

Once you have access to the fuel pump, you can disconnect the old one and install the new one. It is highly recommended to have a professional install it for optimal results. You can find a replacement fuel pump for your 2005 Dodge Durango online or at a local auto parts store. When purchasing a new fuel pump, make sure to get one that is compatible with your vehicle's specific make and model.

Additionally, the fuel pump relay and fuse can be found in the engine compartment fuse box, closest to the firewall. There are two fuse boxes, and you want the one with two rows of black relays. The fuel pump relay is the left relay in the row of four, and the 20 amp fuel pump fuse is located above and to the right of this row.

It is important to note that a fuel pump replacement may be necessary if your engine is struggling to maintain speed, making unusual noises, or hesitating at start-up or take-off. A bad fuel pump can also cause your engine to overheat, so it is important to address these issues promptly to avoid further complications.

The fuel pump is located inside the fuel tank

To change the fuel pump on a 2005 Dodge Durango, you will need to remove the fuel tank as there is no access panel. This is because the fuel pump is located inside the fuel tank.

Step 1: Remove the Fuel Tank

• Use a floor jack to support the plate and lift the fuel tank.
• Ensure the tank is adequately supported before proceeding.

Step 2: Access the Fuel Pump

• Once the tank is lowered, you will need to reach up and remove the bolts holding the fuel pump in place.
• Use a gear wrench or ratchet with a swivel socket and extensions to remove the bolts.

Step 3: Replace the Fuel Pump

• With the bolts removed, you should now be able to access the fuel pump.
• Carefully remove the old fuel pump and any associated components, such as the sending unit or fuel level sensor.

Step 4: Install the New Fuel Pump

• Take your new fuel pump and ensure it is the correct replacement for your Durango.
• Follow the manufacturer's instructions for installation, ensuring a proper fit and secure connection.

Step 5: Reinstall the Fuel Tank

• After confirming the new fuel pump is functioning correctly, carefully raise the fuel tank back into position.
• Secure the tank in place and reattach any disconnected components.

Remember to exercise caution when working with fuel systems, and always refer to a qualified mechanic if you are unsure about any part of the process.

The fuel pump is not coming on

If your 2005 Dodge Durango's fuel pump is not coming on, there are a few things you can try. Firstly, check if the check engine light comes on when you turn the key to the 'on' position. If it does, this indicates a possible issue with the fuel pump. Next, check if the engine runs on starting fluid. If it does, it means the engine is getting fuel, and the issue may lie elsewhere.

Another thing to check is whether the fuel pump is getting power. If it is not, you should then check the inputs to the fuel pump relay, as per the wiring diagram. The fuel pump relay should get two powers and one ground to activate and send power to the fuel pump. If the fuel pump is getting power and still not working, it may be faulty and need replacing.

If your Durango has been experiencing intermittent fuel pump failure, where it turns over but does not start, this could be due to a faulty TIPM/Power Distribution box or fuel pump module. It is worth noting that the 2014 Durango has two fuel pump modules, and issues with either of these could cause the symptoms you are experiencing.

If you are unsure about what to do, it is always best to consult a professional mechanic or a Dodge specialist.

There is no fuel pump reset switch

First, check that the fuel pump is receiving power. If there is no power, check the voltage at the fuel pump relay output and the IPM. If there is power at the relay output and the IPM, follow the wire to the intermediate connector and then to the fuel pump motor. There may be a poor connection somewhere along this circuit.

If there is no power at the relay output, check that the PCM is grounding the wire at key-on and while cranking. If the PCM is grounding the wire, check the resistance of the wire where the fuel pump relay plugs in to the connector on the pump.

If the fuel pump is receiving power but still not working, it may be defective. Test the pump by jumping a wire from the power source to the pump. If the pump works when jumped, then there is likely a problem with the wiring or the fuel pump relay.

In some cases, the fuel pump may not be receiving power due to a broken wire or corroded connector. Check the wiring harness for any signs of damage or corrosion.

Additionally, the fuel pump may not be working due to a faulty crank position sensor or a problem with the security system. If the crank position sensor is defective, the fuel pump relay will not stay engaged. The factory security system may shut down the fuel pump if an invalid key is used, but this will result in a 'start-stall-start-stall' condition rather than a no-start situation.

Finally, if the fuel pump is not working, it may be necessary to drop the fuel tank and replace the pump. This is a complex procedure and should only be attempted by experienced mechanics.

The fuel pump relay and fuse are located in the engine compartment fuse box

The fuse block, or power distribution center, is located in the engine compartment, behind which are the grounds. There are two grounds at this location, bolted to the fender. The forward-most ground, #G114, is the ground for the fuel pump module.

The fuel pump module is the fuel pump and sending unit assembly

The fuel pump module is engineered with superior quality components to ensure optimal performance and long-lasting durability. It features high-efficiency turbine technology for quiet and precise fuel delivery, and carbon commutator technology for improved durability and robust performance. The return porting is modified to increase flow, resulting in lower failure rates, and the convoluted tubing is upgraded to improve durability and resist tube wear failure.

The fuel pump module is designed for straightforward installation and uncomplicated integration. It is also rigorously assessed to ensure quiet operation, unmatched performance, and long-lasting durability.

When replacing the fuel pump module, it is important to make sure that the new part matches the exact specifications of the old part. This includes matching the part number, vehicle make and model, and year. It is also recommended to consult a professional mechanic or refer to a repair manual for detailed instructions on how to replace the fuel pump module on a 2005 Dodge Durango.
