Injector Fuel Leakage

  1. Remove dynamic chamber, if necessary. Loosen delivery pipe attaching bolts. Remove delivery pipe. Using wire, secure injectors tightly onto delivery pipe.
    CAUTION: Ensure injectors are securely tied to delivery pipe. If not properly secured, fuel may spray from loose connections.
  2. Install jumper wire between 2 terminals of fuel pump test circuit connector. See BASIC TESTING - 4-CYL for test connector location. Turn ignition on. Check that no fuel leakage exists at injectors. After 5 minutes, only a slight amount of fuel leakage is acceptable.
NOTE: Injector delivery volume information is not available for B2600i and MPV with 2.6L engine.
