- Using mechanics wire, secure each fuel injector to fuel rail. Disconnect fuel injector connectors. Remove fuel rail assembly from intake manifold. See REMOVAL, OVERHAUL & INSTALLATION article. Reconnect fuel lines to fuel rail. Locate underhood DLC-1 in left side of engine compartment.
- Connect a fused jumper wire between underhood DLC-1 terminals F/P and GND. See Fig 1 . Turn ignition switch 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 excessive fuel leakage is present, replace injector.
