Injector Fuel Leakage
- Remove fuel rail assembly from intake manifold. See appropriate engines article in the ENGINES section. Reconnect fuel lines to fuel rail. Connect a jumper wire between data link connector terminal FP and chassis ground. See Fig 1 .
- Turn ignition on and check for fuel leaks from injectors. Fuel leakage should be less than one drop every 2 minutes. If fuel leakage exists, remove injector and check "O" ring and fuel rail for damage. Replace as necessary.
REGULATED FUEL PRESSURE
| Model | @ Idle W/Vacuum psi (kg/cm2 ) | @ Idle W/O Vacuum psi (kg/cm2 ) |
|---|---|---|
| B2300 | 35-40 (2.5-2.8) | 35-46 (2.5-3.2) |
- Using mechanics wire, secure each fuel injector to fuel rail. Disconnect fuel injector connectors. Remove fuel rail assembly from intake manifold. See appropriate engines article in the ENGINES section. Reconnect fuel lines to fuel rail. Locate data link connector in left side of engine compartment.
- Connect a jumper wire between data link connector terminals F/P and GND. See Figure . 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.
