Fix It

Put your key into the 4Runners ignition and turn on the cars electrical system without starting the car.

Use a flathead screwdriver or your fingers to pry the dashboard panels off your ignition cylinder.

Locate the alarm transmitter in the ignition cylinder. This is a small black box with a switch on it labeled "Valet Switch."

Turn the valet switch to the "Off" position and wait until the LED light goes out.

Put the dashboard panels back onto the ignition cylinder.

Plug the OBD I scan tool into the port under the drivers side dashboard near the steering column. Dont force it in. Just turn it until it fits so you dont damage the pins.

Put the key into the ignition and turn it to the "On" position, but dont crank the engine. Wait while the scan tool retrieves the codes.

Find and select the "Delete Codes" option. This will clear the transmission codes as well as other trouble codes. The computer is now reset. Unplug the scan tool from the port.

Start the engine and verify that all warning lights have shut off of the instrument panel.

Remove the negative battery cable with a socket wrench. This prevents you from starting the engine and discharging fuel during the fuel injector installation. Remove the cap from the fuel tank to relieve the fuel tank pressure.

Remove the cap from the fuel pressure relief valve on the fuel rail. Connect fuel pressure gauge T80L-9974-A to the relief valve, and place the drain tube for the fuel pressure gauge into a container suitable for gasoline. Open the valve on the fuel pressure gauge to drain the fuel system. Disconnect the fuel pressure gauge from the relief valve, and replace the relief valve cap.

Detach the vacuum line from the fuel pressure regulator. Remove the fuel lines from the fuel rail, and unplug the electrical connectors from the fuel injectors. Disconnect the retaining bolts for the fuel rail assembly with a socket wrench, and remove the fuel rail from the fuel injectors. Pull the fuel injectors while gently rocking them back and forth to remove them from the intake manifold.

Coat a pair of new O-rings with light engine oil, and mount them on each fuel injector. Install the fuel injectors into their sockets on the intake manifold, and twist them back and forth gently to properly seat them.

Push the fuel rail down onto the fuel injectors, and ensure that you fully seat the injector O-rings into the caps on the fuel rail. Connect the retaining bolts for the fuel rail as you hold the fuel rail in position. Tighten the retaining bolts to between 71 and 106 inch-pounds with a torque wrench. Attach the fuel lines for the fuel rail, and connect the vacuum line to the fuel pressure regulator.

Connect the cable for the negative battery terminal with a socket wrench, and turn the ignition on to pressurize the fuel system. Correct any fuel leaks, and disconnect the negative battery terminal.

Attach the electrical connectors for the fuel injectors, and connect the negative battery terminal. Start the engine, and allow it to idle for two minutes. Turn the engine off, and correct any fuel leaks.

Drain approximately 2 gallons of radiator fluid from the petcock located on the bottom of the radiator into a clean drain pan. Use a pair of pliers to open the petcock if you cannot open it by hand.

Follow the upper radiator hose to the thermostat housing located on the engine. Remove the hose clamp with a pair of pliers and pull the hose off the engine.

Remove the bolts that secure the housing to the engine with a socket and ratchet. Use the ratchet extension bar supplied with your socket set to avoid hitting any accessories located around the thermostat housing.

Remove the thermostat housing and housing gasket off the engine. Pull the old thermostat out of the engine.

Clean the surface of the engine and the bottom of the thermostat housing with a clean towel. Use a wire brush if you cannot get the old gasket material off the surfaces.

Place the new thermostat into the engine with the large spring submerged into the engine.

Place the gasket over the thermostat and then bolt the thermostat housing back onto the engine.

Place the hose back onto the thermostat and secure it with a hose clamp.

Pour the 2 gallons of fluid into the radiator filler cap located on the top of the radiator.

Disconnect the cable from the negative battery terminal with a socket wrench. Open the filler cap on the fuel tank to relieve the pressure in the fuel tank. Remove the air cleaner from the intake manifold.

Squeeze the two tabs on the fuel injectors electrical connector, and pull it straight up to disconnect the electrical wiring from the fuel injector. Disconnect the cover for the fuel meter with a socket wrench, and discard its gasket.

Lift the fuel injector from the fuel meter with tool No. J-26868, and remove the small O-ring from the fuel injector. Remove the fuel filter from the injector by twisting the fuel filter back and forth. Remove the large O-ring and washer from the injector cavity in the fuel meter.

Coat the new small O-rings in automatic transmission fluid, and install them to the nozzle end of the fuel injector. Place the new washer into the injector cavity of the fuel meter, so that it is flush with the top of the cavity.

Install the new fuel injector so the lug on its base aligns with the notch in the injector cavity. Push the fuel injector down to seat it within the injector cavity, and ensure the injectors electrical terminals are parallel to the shaft of the throttle.

Replace the gasket for the fuel meter cover, and fasten the cover with a socket wrench. Attach the electrical connector for the fuel injector. Start the engine and check for fuel leaks.

Ensure the engine is completely cold to avoid injury from hot oil. Place a drain pan under the engine oil and remove the drain bolt on the oil pan with a socket wrench. Let the oil drain into the drain pan and replace the drain bolt. Store the oil for later use.

Remove the mounting bolts for the oil pan with a socket wrench and disconnect the oil pan from the bottom of the engine. Detach the oil pick-up tube from the oil pump.

Remove the mounting bolts that fasten the oil pump to the bottom of the engine with a socket wrench. Detach the oil pump from the engine and discard the oil pump gasket.

Mount a new gasket to the new oil pump and mount the new oil pump to the bottom of the engine. Tighten the mounting bolts to 14 foot-pounds with a torque wrench. Attach the oil pickup tube to the oil pump.

Install the oil pan and fasten the mounting bolts with a socket wrench. Replace the oil that you previously drained from the engine.

Open the door of your Mustang and slide a jack under the door. Place a piece of wood between the bottom of the door and the jack, and raise the wood with the jack until the door is resting on the wood.

Locate the top pin in the center of the door hinge and tap the bottom of the pin with a hammer to push it up. Do not drive the pin out of the hinge; just push it high enough to create a gap between the top of the hinge and the head of the pin.

Slide a flat pry bar under the head of the pin and pry it up and out of the hinge as you stabilize the door to keep it from falling over. Move the bar to the bottom pin and pry it out.

Lift the door off the hinges and set it aside.
