Injector Fuel Leakage
- Using mechanics wire, secure each fuel injector to fuel rail. Disconnect fuel injector connectors. Remove fuel rail assembly from intake manifold. See appropriate ENGINE article in the ENGINE MECHANICAL section. Reconnect fuel lines to fuel rail. Locate underhood Data Link Connector (DLC) in left side of engine compartment.
- Connect a jumper wire between underhood DLC terminals F/P and GND. See Fig 1
. Turn ignition on. Tilt injectors about 60 degrees and check injector nozzles for fuel leaks. Fuel leakage should be less than one drop every 2 minutes. If fuel leakage exists, replace injector.
