The fuel rail is removed for replacement if damaged (breakage of fittings), to replace nozzles or gain access to other nodes.
1. Reduce the pressure in the supply system (see «Reducing the pressure in the power system»).
2. Disconnect the wire from the terminal «minus» battery.
3. Squeeze the latch...
4.... and disconnect the wiring harness block from the mass air flow sensor.
5. Remove the fuel pressure pulsation compensator (see «Replacing the fuel pressure pulsation compensator»).
6. Slide the retaining clip on the fuel supply hose end.
7. Press the release button...
8.... and disconnect the fuel supply hose from the fuel rail pipe.
9. Squeeze the latch...
10.... and disconnect the wiring harness connector from the canister purge valve.
11. Squeeze the latch...
12.... and disconnect the wiring harness block from the absolute pressure sensor in the intake pipe.
13. Prying off with a plastic spudger or screwdriver, disconnect the absolute pressure sensor harness holders from the canister purge valve bracket...
14.... and fuel injectors.
15. Pull out the stopper of the clamp of the block of the wiring harness...
16.... after it, squeeze the latch...
17.... and disconnect the block from the valve of the variable valve timing system.
18. Loosen the clamp fastening the air supply hose to the nozzle of the throttle assembly and remove the hose from the nozzle.
19. Slide the stopper...
20.... then squeeze the clamp of the wiring harness block...
21.... and disconnect the block from the throttle assembly.
22. Turn out two screws of fastening of an arm of the valve of a purge of an adsorber and take the valve with an arm aside.
23. Remove the crankcase ventilation hose (see «Cleaning the crankcase ventilation system»).
24. Overcoming the resistance of the clamps, disconnect the rear holder of the engine wiring harness from the cylinder head cover.
25. Pry off with a screwdriver...
26.... and remove the cover of the side holder of the engine wiring harness.
27. Press the two latches with a screwdriver and disconnect the side holder of the engine wiring harness from the cylinder head cover.
28. Disconnect the tip from the engine «mass» fuel rail wires by unscrewing the bolt securing the tip to the cylinder head...
29.... and the screw of fastening to an inlet pipe.
30. Move the stopper...
31.... then squeeze the latch...
32.... and disconnect the wiring harness connector from the fuel injector. Disconnect the pads from the remaining injectors in the same way.
33. Turn out two bolts of fastening of a fuel stage to an inlet pipe...
34.... and remove the ramp, removing the nozzles from the intake pipe holes.
WARNING: If any injector remains in the intake pipe when the rail is removed, be sure to replace that injector retainer.
35. If necessary, remove the nozzles from the ramp (see «Removing, checking and installing injectors»).
NOTE: Replace the injector O-rings with new ones each time the fuel rail is removed or disassembled.
36. Install the fuel rail in the reverse order of disassembly and removal, lubricating the injector o-rings with engine oil.
37. Having connected the fuel hose to the rail, start the engine and check the tightness of the connection of the hose with the rail and the injector seals.
