Replacing Fuel Pump In '98 Dodge Stratus: Step-By-Step Guide

Changing the fuel pump on a 1998 Dodge Stratus is a complex process that requires a significant amount of automotive knowledge and skill. It is important to note that the electric fuel pump is not serviceable, and if it needs to be replaced, the entire fuel pump module must be swapped out. Before beginning any work, it is crucial to perform the Fuel System Pressure Release procedure and ensure that the vehicle is in a well-ventilated area to avoid any safety hazards. The process involves multiple steps, including removing the fuel tank, disconnecting various components, and carefully installing the new fuel pump module. It is always recommended to refer to the Dodge Service Manual for detailed instructions and diagrams.

Remove fuel filler cap and perform Fuel System Pressure Release procedure

To remove the fuel filler cap and perform the Fuel System Pressure Release procedure on a 1998 Dodge Stratus, follow these steps:

Firstly, remove the fuel filler cap. This is a simple process and can be done by hand. Next, perform the Fuel System Pressure Release procedure. This is important to ensure your safety and avoid any accidents.

• Disconnect the negative cable from the auxiliary jumper terminal. This will cut off power to the fuel system.
• From inside the trunk, disconnect the pump wiring jumper from the main body harness. The 4-pin connector is usually located under the trunk mat on the left side, near the base of the shock tower.
• Remove the fuel cap slowly. This will release the built-up pressure in the tank.
• Drain the fuel from the tank. Position a fuel-approved container under the drain plug, which is located on the bottom left edge of the tank.
• Remove the drain plug and allow the fuel to drain completely. Reinstall the drain plug when the tank is empty.
• Disconnect the fuel tank from the rubber fill hose. Be cautious as there may be fuel remaining in the fill tube. Wrap shop towels around the hoses to catch any spillage.

By following these steps, you will safely release the fuel system pressure and be ready to perform further maintenance or repairs on your 1998 Dodge Stratus. Remember to work in a well-ventilated area and avoid any potential ignition sources during the process.

Disconnect negative cable from auxiliary jumper terminal

To disconnect the negative cable from the auxiliary jumper terminal of your 1998 Dodge Stratus, you will need to follow a few important steps to ensure your safety and the integrity of the vehicle's electrical system. Here is a detailed guide:

Safety First:

• Park your car on a level surface and engage the parking brake.
• Make sure the engine is off and the keys are removed from the ignition.
• Locate the auxiliary jumper terminal, which is usually found in the engine bay, connected to the negative battery terminal.

Disconnecting the Cable:

• Identify the negative cable connected to the auxiliary jumper terminal. It is typically black and should be clearly marked with a "-" symbol or a black clamp.
• Using the appropriate size wrench or socket, loosen the nut that secures the negative cable to the auxiliary jumper terminal. Do not remove it yet.
• Once loosened, carefully lift the cable slightly to ensure that it is not stuck or bound to the terminal.
• Completely remove the nut and set it aside in a safe place.
• Gently pull on the cable to detach it from the terminal. If it resists, wiggle it gently side to side while pulling to free it. JHoop, a Dodge Technician, recommends performing the Fuel System Pressure Release procedure before proceeding further.
• Place the cable away from the terminal and any metal parts of the car to avoid accidental contact.

Prevent Accidental Contact:

• It is crucial to ensure that the negative cable does not accidentally touch any metal parts of the car, including the auxiliary jumper terminal, while you are working.
• You can use a suitable insulator, such as a piece of rubber or electrical tape, to cover the exposed terminal temporarily.
• Make sure the cable is secured and cannot accidentally swing and make contact.

Work Safely:

• Always be cautious when working around a car battery and electrical system.
• Avoid wearing metal jewellery or clothing with metal fasteners that could accidentally touch the battery or electrical components.
• Never allow the positive (+) and negative (-) cables to touch each other or any other metal parts of the car simultaneously.

Remember, working on a car's electrical system can be hazardous if not done properly. If you are unsure or uncomfortable with any part of the process, it is best to consult a qualified mechanic or seek advice from a trusted auto repair source.

Remove fuel tank

To remove the fuel tank from a 1998 Dodge Stratus, you will need to follow these steps:

Release the Fuel System Pressure

This is an important safety precaution to avoid any accidents. Make sure to do this before proceeding with any other steps.

Disconnect the Negative Cable

Locate and disconnect the negative cable from the auxiliary jumper terminal.

Remove the Fuel Filler Cap

This will help relieve any remaining pressure in the fuel system.

Drain the Fuel Tank

Position a fuel-approved container underneath the drain plug, which is located on the bottom left edge of the tank. Once you have drained the fuel, reinstall the drain plug and tighten it securely.

Disconnect Fuel Lines and Vapor Line

Disconnect the fuel lines from the fuel pump module. Be cautious as there may still be fuel in the fill tube. Also, disconnect the vapor line from the tank-mounted rollover valve, which is located at the rear of the tank.

Remove the Fuel Tank Straps

Remove the bolts securing the fuel tank straps.

Remove the Fuel Tank

With the straps removed, you can now carefully slide the fuel tank forward to clear the suspension cross-member and then lift it out of the vehicle.

It is important to work in a well-ventilated area and avoid any potential ignition sources when performing this task. Always refer to the Dodge Service Manual for detailed instructions and diagrams specific to your vehicle.

Disconnect fuel filter lines from fuel pump module

To disconnect the fuel filter lines from the fuel pump module of a 1998 Dodge Stratus, you will need to follow a careful procedure to ensure your safety and avoid any damage to the vehicle. Here is a detailed, step-by-step guide:

Preparation:

Before beginning any work, it is crucial to ensure your safety and the protection of your vehicle. Put on appropriate safety gear, such as gloves and eye protection. Move the vehicle to a well-ventilated area, and make sure there are no sources of ignition nearby. It is also recommended to have a fire extinguisher nearby as an extra precaution.

Initial Steps:

• Remove the fuel filler cap to release the pressure in the fuel system. This is an important safety measure to prevent any accidental fuel spray or leakage during the process.
• Disconnect the negative cable from the auxiliary jumper terminal. This will disconnect the power source to the fuel pump.
• Remove the fuel tank. Refer to a repair manual or seek guidance from a professional if you are unsure about this step, as it may involve additional procedures.

Disconnecting Fuel Filter Lines:

• Locate the fuel filter lines connected to the fuel pump module. These lines are responsible for carrying fuel between the tank and the engine.
• Using appropriate tools, carefully disconnect the fuel filter lines from the fuel pump module. This may involve releasing quick-connect fittings or clamps holding the lines in place. Be gentle to avoid any damage to the lines or the module.
• Once disconnected, set the fuel filter lines aside in a safe place, away from any potential sources of ignition or heat.

Additional Precautions:

It is important to note that the fuel reservoir and the fuel pump module may still contain fuel even after draining the tank. Therefore, be extremely cautious during this process to avoid any accidental fuel spillage. Have absorbent materials or a suitable container nearby to catch any fuel that may spill during the disconnection process.

By following these steps, you will be able to safely and effectively disconnect the fuel filter lines from the fuel pump module of your 1998 Dodge Stratus. Remember to work cautiously and refer to reliable resources or seek professional assistance if needed.

Remove fuel pump relay from the fuse and relay box

To remove the fuel pump relay from the fuse and relay box in the engine bay of a 2005 Dodge Stratus, first locate the relay box. Check the diagram on the cover of the box to identify the location of the relay. Once you've found the relay, start the engine—it should cut off. Try starting the engine again to relieve fuel pressure.

Next, use a wrench to remove the negative battery terminal nut, then lift off the negative cable and set it aside.
