Replacing Fuel Pump In 2004 Mitsubishi Endeavor: Step-By-Step Guide

If the fuel pump in your 2004 Mitsubishi Endeavor is acting up, you may be able to fix it yourself. The fuel pump is located in the vehicle's gas tank and can be accessed through an access panel in the passenger compartment. If there is no access panel, you will need to drain the fuel tank and lower it from the vehicle. Once you have access to the pump, you can remove it and install a new one, along with any reusable brackets and pick-up screens. You can purchase a new fuel pump for your 2004 Mitsubishi Endeavor online or at an auto parts store. The cost of a new fuel pump can vary depending on the brand and retailer, but it is generally around $100 to $200. Keep in mind that labour costs for fuel pump replacement can be high, so if you're not comfortable with the task, it's best to leave it to a professional.

Fuel pump testing

To test the fuel pump on a 2004 Mitsubishi Endeavor, you can start by checking the fuel pressure via a quick connect located below the intake hose in the engine bay. Connect a fuel pressure tester here and check the fuel pressure while cranking the engine. If there is no fuel pressure, you will need to verify that you have power and ground at the fuel pump when the engine is rotating.

If there is no power and ground at the fuel pump, check your wiring and relays for damage, and re-check your live scan tool data to ensure you are seeing engine RPM. If there is power and ground at the fuel pump but no fuel pressure, a fuel pump replacement is likely necessary.

Fuel pump removal

To remove the fuel pump from a 2004 Mitsubishi Endeavor, you must first test the pump to ensure it is faulty. If it is, you can then proceed to remove the fuel pump from the tank.

There are two methods for accessing the fuel pump, depending on your vehicle's configuration. If there is an access panel above the tank in the passenger compartment, you can use this to reach the pump. If not, you will need to drain the fuel from the tank and then lower the tank from the vehicle to gain access to the pump.

Once you have access to the pump, you must remove the fuel pump supply and return hoses, EVAP system hoses, and electrical connections. After detaching these components, you can remove the fuel pump from the tank.

If your fuel system uses an in-line external filter, it is recommended to replace the filter during this process. Additionally, unless the fuel filter has been replaced recently, it is advisable to install a new fuel filter when replacing the fuel pump.

Fuel pump installation

To install a fuel pump in a 2004 Mitsubishi Endeavor, you will first need to test the fuel pump to ensure it is faulty. If it is, you will need to remove it from the tank through an access panel above the tank in the passenger compartment. If no access panel exists, you will need to drain the fuel from the tank and then lower the fuel tank from the vehicle to access the pump.

Once you have access to the fuel pump, you will need to remove the fuel pump supply and return hoses, as well as the EVAP system hoses and electrical connections to the pump. Once the pump is out, you can attach any reusable brackets and pick-up screens to the new pump before installing it. If your fuel system uses an in-line external filter, you should replace the filter at this time as well. Re-establish all hoses and electrical connections, add fuel to the tank, and run the engine to test for leaks.

It is important to note that the fuel in the gas tank cools and lubricates the fuel pump, so it is recommended to keep the gas tank at least a quarter full to maximize the life of the new fuel pump.

Fuel pump problems

Fuel pumps are designed to last well past 100,000 miles under normal conditions, so it's unlikely that you will ever have to change one. However, if you are experiencing problems with your fuel pump, there are several warning signs to look out for.

Firstly, a damaged fuel pump may make a loud, whining sound coming from your fuel tank. This noise often gets louder as the pump works harder to deliver fuel. Secondly, if your vehicle struggles to start or stalls while driving, this could be due to a faulty fuel pump that is unable to deliver enough fuel to the engine. This may be especially noticeable when accelerating or driving uphill. Thirdly, a failing fuel pump may cause your engine to surge, with the vehicle repeatedly picking up and dropping speed. Fourthly, a bad fuel pump can result in lower gas mileage and decreased fuel efficiency as excess fuel is allowed to enter the engine and go to waste. Finally, if your vehicle fails an emissions test, it could be because a malfunctioning pump is causing the engine to run rich, leading to higher levels of harmful emissions.
