How to remove the fuel injector on Toyota 4Runner?

The procedure to detach the 2UZ-FE engine fuel injector starts with emptying the fuel system pressure. First properly discharge the fuel system pressure before removing both cap nuts and the throttle body cover sub-assembly. The removal process starts by detaching vacuum hoses from P/S idle-up, fuel pressure regulator, and ventilation hose then taking off the air cleaner hose assembly. Start by removing all 2 union bolts along with 4 gaskets from the No. 1 fuel pipe sub-assembly then move to the bolts needed to detach the fuel pipe sub-assembly. Lifting away the fuel return pipe sub-assembly from the fuel pressure regulator will be possible after removing the No. 2 fuel pipe clamp and 3 bolts which serve to disconnect this sub-assembly from the fuel pressure regulator. The fuel hose requires disconnection after the removal of both pulsation damper and 2 gaskets followed by No. 1 fuel hose separation. The separation of the No. 1 vacuum switching valve sub-assembly from the intake manifold becomes possible after removing all bolts. The fuel injector connectors must be disconnected along with the removal of 3 engine wire bolts. Start by unthreading the 2 nuts to remove the fuel delivery pipe sub-assembly before extracting it upward straight. Then continue by removing the No. 2 fuel delivery pipe sub-assembly using the same procedure. Through the final step remove the fuel injector assembly from the delivery pipe while maintaining injector position to avoid damaging the O-ring before taking out its components.

How to install the fuel injector assembly on Toyota 4Runner?

The first step for installing the fuel injector assembly includes fitting a new grommet and insulator onto the injector. The O-ring on injector requires a groove inspection for foreign particles and damage before installation with gasoline-treatment of new O-rings and application to the injector. Use the delivery pipe to mount the injector which should easily rotate in opposite directions but requires replacement of the O-ring with a fresh one if it cannot turn properly. When installing the injector along with the delivery pipe to the intake manifold for the No. 2 fuel delivery pipe sub-assembly turn it at approximately 45 degrees in both directions. Fasten two nuts onto the delivery pipe injector combination after inserting the spacer between the intake manifold and delivery pipe while tightening the nuts with 21 Nm (214 kgf-cm, 16 ft-lbf). The fuel delivery pipe sub-assembly requires you to perform this process again. The fuel hose installation requires two new gaskets along with torquing the fuel main hose with the fuel pressure pulsation damper to 39 Nm (400 kgf-cm, 29 ft-lbf). The mechanic should install the No. 1 vacuum switching valve assembly first then secure the No. 3 fuel pipe sub-assembly while tightening these components to 18 Nm (185 kgf-cm, 13 ft-lbf) and 7.5 Nm (80 kgf-cm, 66 ft-lbf) respectively. The No. 1 fuel pipe sub-assembly requires installation using bolts combined with 4 new gaskets by means of 2 union bolts which must reach a torque of 39 Nm (400 kgf-cm, 29 ft-lbf). After air cleaner hose install, verify there is no fuel leakage before attaching the throttle body cover sub-assembly at 7.5 Nm torque.

The Fuel Injector is an important adjunct of Toyota 4Runner automobiles in which fuel is directly injected into the engine cylinder at the direction of the Engine Control Module. This system is called "returnless," cuts the fuel lines and delivers the optimal possible air-fuel blend for the load of the engine. When an injector fails, the engine's performance diminishes, power reduced, and fuel consumption is compromised; the catalytic converters and oxygen sensors get negatively affected too. However, for efficiency, damaged fuel injectors should be replaced as soon as possible because the efficiency of the vehicle may be affected by the faulty part. The Fuel Injector in Toyota 4Runner automobiles is responsible for accurately regulating the flow of fuel for improved engine operations and engine performance in the replacement of the quite archaic carburetor system.
