Fuel injection system components for 1.4L, 55 and 74 kW petrol engines
1 – oil filler cap; 2 – upper engine casing with air filter; 3 – wire holder; 4 – fuel rail mounting bolt; 5 – nipple for measuring pressure in the system; 6 – fuel rail with injectors; 7 – engine intake pipe mounting bolt; 8 – brake booster vacuum hose; 9 – throttle actuator connector block; 10 – adsorber purge hose; 11 – inlet pipe; 12 – gasket; 13 – exhaust gas recirculation tube mounting bolt; 14 – exhaust gas recirculation pipe; 15 – second lambda probe (for engines that meet Euro-4 standards); 16 – connecting block of the second lambda probe; 17 – lambda probe; 18 – lambda probe connector; 19 – crankshaft speed sensor; 20 – sensor mounting bolt; 21 – intake pipe gasket; 22 – spring holder; 23 – connecting block; 24 – coolant temperature sensor; 25 – plug; 26 – sealing rings; 27 – thermostat housing mounting bolt; 28 – thermostat housing; 29 – fuel line; 30 – control unit connecting blocks; 31 – engine control unit; 32 – block bracket; 33 – bracket mounting bolts
Fuel rail with injectors for 1.4 l, 55 and 74 kW engines
1 – fuel line; 2 – fuel rail mounting screw; 3 – fuel rail; 4 – nipple for measuring pressure in the system; 5 – injector retainer; 6 – sealing ring; 7 – nozzle
1. Disconnect the wire from the "-" terminal of the battery.
2. Remove the upper engine cover (see subsection 2.1).
3. Disconnect the connectors with wires from the injectors.
4. Disconnect from fuel rail 3 (see the figure Fuel rail with injectors for 1.4 l, 55 and 74 kW engines) fuel line 1.
5. Unscrew the two screws 2 securing the fuel rail.
6. Pull the fuel rail along the injector axes and remove it. In this case, the injectors should come out of the holes in the engine intake pipe and remain on the ramp. If any injector remains in the intake pipe, its sealing rings 6 and retainer 5 must be replaced.
7. Remove the 5 injector retainers.
8. Pull and remove injectors 7 from fuel rail 3.
9. Replace the 5 injector retainers if you find any cracks on them.
10. Replace any torn, cracked or loose sealing rings on the 6 injectors.
11. Install the injectors in reverse order. At the same time, lubricate the injector sealing rings with gasoline.
