Checking the technical condition
1. Turn off the ignition.
2. Disconnect the injector connector.
3. Measure the resistance between terminals 1 and 2 of the injectors.
4. Check that the resistance is within specification.
Withdrawal
1. Turn the ignition key to the OFF position and disconnect the negative (-) battery wire.
2. Relieve residual pressure in the fuel line.
Attention. After removing the fuel pump relay, a fault code may appear (DTC). Clear this code with a diagnostic system scanner (GDS) after completion of work to relieve residual pressure in the fuel line.
3. Disconnect the injector connector (A).
4. Remove the bolt (IN) harness mounting bracket.
5. Turn away a fastening nut and disconnect a bringing fuel line (WITH).
6. Turn away a bolt of fastening (D) and remove the fuel rail and injector assembly.
7. Remove the clips (A) and disconnect the injectors from the fuel rail.
Installation
Attention.
- Tighten the component mounting bolts to the correct torque.
- Be careful not to drop the component. In the event of a drop, the component must be carefully checked before installation.
- Lubricate the injector O-rings with engine oil.
- When installing, inspect the injector o-rings.
- Installation is carried out in the reverse order of removal.
Note: Tightening torque:
- Fuel rail mounting bolt: 18.6 - 23.5 Nm.
- Nut for securing the fuel rail and fuel supply line: 7.8 - 9.8 Nm.
