• Q: How to service and repair the fuel injector on 2001 Toyota Land Cruiser?

  A: First service and repair the fuel injector by taking out the V-bank cover, intake air connector and fuel pressure pulsation damper but keep a shop towel below the delivery pipe while gradually relaxing the pulsation damper. The first step starts with cable accelerator disconnection from the engine while removing two nuts and the accelerator cable bracket. The engine wire protector needs disconnecting from the upper intake manifold through this process: unfastening the PCV hose from the PCV valve then taking off the VSV for EVAP followed by accelerator cable clamp removal while also removing the No.1, No.2, and No.3 V-bank cover brackets before disengaging the two bolts used for engine wire protector and engine wire clamp separation from the No.1 engine hanger. The right-hand delivery pipe engine wire needs disconnecting while removing its two wire clamps. When removing the delivery pipes and injectors, be cautious not to drop the injectors; remove the bolt holding the clamp on the fuel return pipe to the left-hand delivery pipe, then remove the bolt, two union bolts, four gaskets, and front fuel pipe, followed by disconnecting the eight injector connectors and removing the four nuts holding the delivery pipes to the lower intake manifold, then take out the two delivery pipes, eight injectors, four spacers, and eight insulators, and finally remove the O-ring and grommet from each injector. Installation begins with installing new grommets for each injector followed by O-ring application using gasoline before placement, then while turning the injectors gently drive them into the delivery pipes with injector connectors oriented outward. First position the two delivery pipes and injector assemblies on the lower intake manifold then secure four new gaskets and two union bolts while tightening them to 39 N.m (400 kgf.cm, 29 ft.lbf) for union bolts and 7.5 N.m (80 kgf.cm, 66 in.lbf) for the bolt. After that temporarily install the four nuts and install the front fuel pipe with its bolt along with four new gaskets and two union bolts. To install the bolt that holds the fuel return clamp on the left delivery pipe requires a torque of 7.5 N.m (80 kgf.cm, 66 in.lbf) while ensuring injector smooth rotation that may require new O-rings. Secure the delivery pipes to the lower intake manifold by tightening the four nuts to 18 N.m and then attach the eight injector connectors. The installation process includes attaching the engine wire to left-hand delivery pipe through two wire clamps followed by attaching the engine wire protector through engine wire clamp connection at the No.1 engine hanger and using two bolts to position this protector. Next is connecting the PCV hose to the PCV valve and attaching the VSV for EVAP to upper intake manifold. Finally complete the installation by attaching the accelerator cable clamp to the No.1, No.2, and No.3 V-bank cover brackets. First, use the two nuts to install the accelerator cable bracket then torque them to 18 N.m (185 kgf.cm, 13 ft.lbf). Next, hook up the accelerator cable to the engine before putting back the fuel pressure pulsation damper and intake air connector and V-bank cover.
