- Remove fuel injector. See FUEL SYSTEM under REMOVAL, OVERHAUL & INSTALLATION article. Purchase new No. 1 Fuel Pipe (23801-20150 for ES300; 23801-20120 on RX300) and take out fuel tube connector from its pipe. See Fig 1. Connect hose and fuel tube connector to fuel pipe. See Fig 2. Install grommet and "O" ring to injector. Connect union and hose to injector. Hold injector and union with clamp. See Fig 3.
- Place fuel injector into a clean graduated container. Place vinyl tube on end of fuel injector to prevent fuel spillage. Connect scan tool to Data Link Connector (DLC) No. 3. Turn ignition on. Turn scan tool on. Select ACTIVE TEST MODE on scan tool. Using scan tool manufacturer's instructions, activate fuel pump.NOTE: Fuel pump may also be operated to pressurize fuel system by applying battery voltage to fuel pump connector terminals. See Figure or Figure . See FUEL SYSTEM in BASIC DIAGNOSTIC PROCEDURES article.
- Connect Fuel Injector Tester (09842-30070) to fuel injector for 15 seconds. See Fig 4. Measure fuel injector volume. Test each fuel injector 2-3 times. Replace fuel injector if fuel injector volume is not within specification. See FUEL INJECTOR VOLUME SPECIFICATIONS table. Ensure difference between fuel injector volume on all fuel injectors is within specification. Disconnect voltage from fuel injector. Check fuel leakage from injector. Leakage should be one drop or less per 12 minutes.FUEL INJECTOR VOLUME SPECIFICATIONS
