Land Cruiser & Sequoia
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sienna, 2002 Toyota Sequoia, and 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Ensure battery is fully charged. Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Disconnect negative battery cable.
- On Land Cruiser, remove intake manifold cover located on top of engine, above intake manifold and intake air connector for access to front fuel pipe at front of driver's side fuel rail (if necessary). See Fig 1. Intake air connector fits between throttle body and air cleaner assembly. On Sequoia, remove throttle body cover and intake air connector for access to front fuel pipe at front of driver's side fuel rail (if necessary). See Fig 1. Intake air connector fits between throttle body and air cleaner assembly.
- On all models, cover union bolt at front fuel pipe at front of driver's side fuel rail with shop towel. Remove union bolt with gaskets, and disconnect front fuel pipe from front of driver's side fuel rail. It may be necessary to remove retaining bolt at center of front fuel pipe when disconnecting front fuel pipe from driver's side fuel rail.
- Install Union (SST 90405-06167), Adapter (SST 09268-41190) and fuel pressure gauge from Fuel Pressure Gauge Set (SST 09268-45014) with front fuel pipe on driver's side fuel rail. See Fig 2. Tighten adapter to 29 ft. lbs. (39 N.m).
- Install negative battery cable. Connect Toyota hand-held tester to data link connector No. 3 at driver's side of instrument panel. See Figure and Figure . Turn ignition on. DO NOT start engine.
- Turn hand-held tester on. Select ACTIVE TEST MODE on hand-held tester. Using hand-held tester manufacturer's instructions, operate fuel pump and note fuel pressure. On Land Cruiser, if hand-held tester is not available, fuel pump may also be activated by connecting battery voltage to specified terminals on fuel pump. See Figure. On all models, fuel pressure should be 38-44 psi (2.7-3.1 kg/cm2 ).
- If fuel pressure is within specification, go to next step. If fuel pressure exceeds specification, replace fuel pressure regulator mounted near center of passenger's side fuel rail. See FUEL PRESSURE REGULATOR under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - V6 & V8 article. If fuel pressure is less than specified, check for leaking fuel hoses or connections, restricted fuel filter, defective fuel pump or defective fuel pressure regulator.
- Remove hand-held tester from data link connector No. 3. Start engine. Note fuel pressure with engine idling. Fuel pressure should be 38-44 psi (2.7-3.1 kg/cm2 ).
- Shut engine off and note fuel pressure. Fuel pressure should remain at least 21 psi (1.5 kg/cm2 ) for a minimum of 5 minutes. If fuel pressure holds as specified, go to next step. If fuel pressure does not hold as specified, check for defective fuel pump, fuel injector or fuel pressure regulator.
- Release fuel pressure. Disconnect negative battery cable. Remove adapter, union and fuel pressure gauge from driver's side fuel rail. Using NEW gaskets, install front fuel pipe on driver's side fuel rail. Tighten union bolt to 29 ft. lbs. (39 N.m) and retaining bolt for front fuel pipe (if loosened) to 66 INCH lbs. (7.5 N.m).
- Install negative battery cable. Check for fuel leaks by activating the fuel pump by using hand-held tester. On Land Cruiser, fuel pump may also be activated by connecting battery voltage to specified terminals on fuel pump to check for fuel leaks. See Figure. On all models, reinstall remaining components.
