Check the fuses and relays before looking at the fuel pump itself
To replace a fuel pump in a Geo Tracker, you should first check the fuses and relays before looking at the fuel pump itself. The Geo Tracker's fuel pump is electric, so it's important to ensure that any issues are not being caused by a blown fuse or faulty relay.
The fuel pump relay in a Geo Tracker is typically located under the dash, near the ECU (Engine Control Unit), and in the area where the fuses are. In some models, it may be inside the glovebox, or mounted on a bracket under the heater fan. The relay is usually green in colour, but it can also be black with a white connector and a pink wire.
To test the relay, you can use a multimeter to check if it is open or closed when it should be powered off. If the relay is faulty, it will need to be replaced.
Additionally, you can check the wires coming off the fuel pump or out of the gas tank to ensure that they are not disconnected. If there is no power to the fuel pump, you can try running a hot wire from the ignition switch or the ignition fuse to the hot wire on the fuel pump as a temporary fix.

Release the fuel system pressure, disconnect the negative battery cable and safely raise your vehicle
To replace the fuel pump in a Geo Tracker, you must first prepare your vehicle for servicing. This involves releasing the fuel system pressure, disconnecting the negative battery cable, and safely raising your vehicle. Here is a detailed, step-by-step guide on how to do this:
Releasing the Fuel System Pressure
Before starting any work on the fuel system, it is crucial to relieve the pressure to avoid the risk of fire or injury. To do this, follow these steps:
- Park your Geo Tracker on a level surface and engage the parking brake.
- Open the hood and locate the fuse box.
- Remove the fuel pump fuse to disable the fuel pump.
- Start the engine and let it run until it stalls due to a lack of fuel. This will relieve the pressure in the fuel lines.
- Turn off the ignition and ensure that the engine is cool before proceeding.
Disconnecting the Negative Battery Cable
Safety is paramount when working on any electrical system in a vehicle. To minimise the risk of electrical short circuits and accidental activation of components, always disconnect the negative battery cable:
- Locate the negative terminal of the battery. It will be marked with a '-' symbol or a black cover.
- Use an appropriate-sized wrench or socket to loosen the nut or bolt securing the cable to the terminal.
- Carefully remove the cable from the terminal.
- Cover the terminal with a piece of tape or insulated cloth to prevent accidental contact.
Safely Raising Your Vehicle
Accessing the fuel pump requires working underneath the vehicle, so it is important to raise and support it securely:
- Place wheel chocks around the front wheels to prevent accidental movement.
- Position jack stands or ramps at the manufacturer's recommended lift points. Refer to your owner's manual if needed.
- Raise the vehicle according to the jack stand or ramp instructions. Ensure it is stable and secure.
- For added safety, lower yourself down on a creeper or lie on a folded blanket to provide some cushioning.
Once you have completed these steps, you can proceed with draining the fuel tank and removing the fuel pump. Remember to work with a partner whenever possible, and always put safety first.

Drain the fuel tank and remove its connections
To drain the fuel tank and remove its connections, follow these steps:
First, ensure you have the necessary equipment for safety and functionality. This includes eye protection, gloves, and a socket wrench. It is also important to work in a well-ventilated area to avoid inhaling any fumes.
Next, release the fuel system pressure and disconnect the negative battery cable. This is an important safety precaution to prevent any accidental ignition of fuel vapors. Once this is done, safely raise your vehicle to gain access to the underside.
Now, you can begin to drain the fuel tank. Place a suitable container under the fuel tank to collect the drained fuel. Be cautious as the fuel may still be pressurized and flow rapidly when the drain plug is removed. You may need to use a socket wrench to loosen the drain plug.
After draining the fuel tank, you will need to remove its connections. This includes the fuel tank mounting fasteners, which can be removed using a socket wrench. Once these fasteners are removed, carefully lower the fuel tank from the underside of your vehicle.
At this point, you will have successfully drained the fuel tank and removed its connections. You can now proceed to the next steps of replacing the fuel pump, which include removing the retaining bolts from the fuel pump and lifting it out of the fuel tank. Remember to refer to a trusted repair manual or seek professional assistance if you are unsure about any part of the process.

Remove the retaining bolts from the fuel pump with a socket wrench
To remove the retaining bolts from the fuel pump with a socket wrench, follow these steps:
First, locate the fuel pump inside the fuel tank. The fuel pump is located underneath the vehicle, and you will need to raise the vehicle safely and drain the fuel tank before accessing the fuel pump. Once you have located the fuel pump, identify the retaining bolts that hold it in place. These bolts are typically located on the top and bottom of the fuel pump, or on the sides, securing it to the fuel tank.
Next, select the appropriate socket size for your socket wrench that fits the retaining bolts. Ensure that the socket wrench is set to turn in the correct direction for removing the bolts, typically counter-clockwise. Place the socket firmly over the head of the retaining bolt and apply force in the required direction to loosen and remove the bolt. Repeat this process for all the retaining bolts, taking care not to drop them into the fuel tank or misplace them, as you will need them again when installing the new fuel pump.
Once all the retaining bolts have been removed, you can carefully lift the fuel pump out of the fuel tank. Be aware that the fuel pump may still be connected to hoses and electrical wiring, so take care not to damage these connections during removal. Place the old fuel pump aside, discarding the old gasket, and prepare to install the new fuel pump by following the kit instructions.

Install the new fuel pump using the kit components
To install the new fuel pump using the kit components, follow these steps:
First, ensure that the new fuel pump is compatible with your Geo Tracker's make, model, engine size, and type. For Geo Trackers manufactured between 1989 and 1998, a 1.6L engine was used, while models produced after 1998 featured a 2.0L engine.
Next, align the holes for the retaining bolts and push the new fuel pump into the tank. Install the retaining bolts and tighten them securely. Reinstall the fuel tank by reversing the removal procedure, ensuring the tank mounting fasteners are tightened to 36.5 ft-lbs with a torque wrench.
If your new fuel pump kit includes a gasket, be sure to install it. Also, if your fuel system uses an in-line external filter, it is recommended to replace it during this process.
Finally, refill the fuel tank and start the engine to test for any leaks.
