Replacing The Fuel Pump In A Toyota Pickup 22R Engine

If you're looking to replace the fuel pump in your Toyota Pickup 22R, you'll first need to locate it. The fuel pump is typically found either bolted to the right front corner of the cylinder head or inside the fuel tank. If your Toyota Pickup is a 1984 or later model with fuel injection, then the fuel pump is definitely located inside the fuel tank.

Once you've located the fuel pump, you have a few options for accessing it. You can try dropping the tank, pulling the bed, or cutting a hole in the bed to create an access port. Each method has its pros and cons, so consider your skills, resources, and the specific characteristics of your vehicle before deciding which approach to take.

Before attempting any fuel pump replacement, it's important to consult a repair manual or seek guidance from a qualified mechanic to ensure you have the necessary tools and safety precautions in place. Working with fuel and electrical systems can be dangerous if not done properly.

Removing the bed of the truck to access the fuel pump

To access the fuel pump in your Toyota Pickup 22R, you will need to remove the bed of the truck. This process will require some time and effort, as well as some additional help. Here is a step-by-step guide to removing the bed of your truck:

Firstly, gather the necessary tools and materials. You will need a wrench, an impact driver, and some good-quality lubricant or penetrating fluid (e.g., PB Blaster, Seafoam Deep Creep, or WD40). Optionally, you can use a propane torch to heat the nuts and make them easier to remove.

Secondly, locate and remove the bed mounting bolts and screws. There are typically eight mounting bolts on the bottom of the bed, three screws in the gas filler neck, and eight screws for the tail lights. Apply lubricant to the bolts and screws and let it soak for a couple of days before attempting to loosen them. If the heads of the screws are stripped, you may need to use a drill to remove them.

Once all the fasteners have been removed, you will need to unclip and disconnect the wiring harness for the license plate and tail lights. Be careful not to damage the wiring during this process.

Finally, with the help of a few friends, lift the bed of the truck and place it aside. Be careful when handling the bed, as it may be heavy and awkward to move.

With the bed removed, you should now have access to the fuel pump. Before beginning any work on the fuel pump, be sure to consult a repair manual or seek advice from a qualified mechanic to ensure you perform the necessary tasks correctly and safely.

Reinstalling the bed will involve reversing the above steps. Be sure to clean and inspect the bed and frame for any rust or damage before reinstalling. If necessary, treat any rusted areas and apply a new undercoat to protect the metal.

Testing the main relay

To test the main relay, you must first locate it. The EFI main relay is located in the fuse/relay block #2, which is on the front right corner of the engine compartment.

Now, to test the relay, you can use a jumper wire to bypass the circuit and power the fuel pump. Place the jumper wire between the terminals FP and B+ in the diagnostic check connector under the hood. The diagnostic check connector is a small rectangular box located near the fuse box, which is marked with the word "DIAGNOSIS".

With the key in the ignition turned to the "ON" position, the B+ terminal will have 12 volts running through it. The FP terminal is for the fuel pump. By placing a jumper wire between these two terminals, you complete the circuit and power the fuel pump directly.

You can use a bent paper clip or a wire as a jumper. If the fuel pump runs with the jumper in place, then the circuit and the pump are good. If the fuel pump does not run with the jumper, then there may be a problem with the wiring or the fuel pump itself.

Draining the fuel from the fuel tank

To drain the fuel from the fuel tank of your Toyota Pickup 22R, follow these steps:

First, locate the fuel tank. This is usually found at the rear of the vehicle, underneath the bed. Place a drain pan or container underneath the tank to collect the drained fuel.

Next, locate the drain plug on the fuel tank. This is typically located at the bottom of the tank. Once you have found the drain plug, place a suitable container underneath to collect the drained fuel.

Now, remove the drain plug using a wrench or socket. Have a rag or towel ready to catch any fuel that may spill. Once the drain plug is removed, allow the fuel to drain completely.

After the fuel has finished draining, replace the drain plug securely. Make sure that the plug is tightened properly to prevent any leaks.

Finally, dispose of the drained fuel safely and responsibly. Do not pour it down the drain or into the environment. Take it to a designated disposal site or recycling centre.

Draining the fuel from your Toyota Pickup 22R fuel tank is an important step when replacing the fuel pump. It ensures that you are working with a dry system and reduces the risk of fuel leaks or spills during the repair process. Always exercise caution when working with fuel and follow local safety guidelines.

Removing the fuel pump bracket from the fuel tank

To remove the fuel pump bracket from the fuel tank of a Toyota Pickup 22R, follow these steps:

First, a warning: do not smoke or work near an open flame when working on the fuel pump.

Now, to begin, drain the fuel from the fuel tank. Then, remove the seven bolts from the fuel pump bracket. Pull out the fuel pump bracket. Remove the two nuts and disconnect the wires from the fuel pump. Pull the bracket from the lower side of the fuel pump. Finally, remove the fuel pump from the fuel hose.
