REMOVAL 1. Relieve the residual pressure from the high-pressure fuel lines to prevent fuel spray.

Due to residual pressure in the high-pressure fuel line, cover the fuel filter with a shop rag to prevent fuel spray.

2. Снимите топливный коллектор вместе с форсунками.

2. Remove the fuel rail together with the injectors.

2. Make sure fuel does not leak after removing the injector.

INSPECTION 1. Measure the injector coil resistance between terminals e of the connector using an ohmmeter.

Specified value: 15.9 ± 0.35 Ω at 20°C

2. Если сопротивление не соответствует диапазону номинальных значений, то замените

2. If the resistance is not within the specified range, replace the injector.

INSTALLATION 1. Install a new injector body O-ring and a new injector nozzle O-ring.

2. Перед установкой нанесите немного веретенного масла или бензина на кольцевую

2. Before installation, apply a small amount of spindle oil or gasoline to the injector nozzle O-ring.

3. While turning the injector slowly left and right, carefully install it into the fuel rail (Translator's note: do not damage the O-ring).

4. После установки проверьте, плавно ли поворачивается форсунка в топливном коллекторе.

4. After installation, check that the injector turns smoothly in the fuel rail.

If the injector does not turn smoothly in the fuel rail, the O-ring may be pinched. In this case, remove the injector from the fuel rail, reinstall it into the fuel rail and check that it turns smoothly.
