Remove the rail and injectors to check and replace the injectors
Reducing the pressure in the fuel system (described in the article - How to remove and disassemble the fuel module of a Nissan Almera car)
Disconnect the negative battery terminal
Remove the protection of the fuel rail, for this:
Move up the power steering reservoir from the bracket of the upper cross member of the radiator frame
We lower the tank so that the hose connecting the tank to the power steering pump is located below the ramp protection.
Through the channels in the ramp protection with a 13 head, unscrew the two nuts of the studs securing the ramp protection.
Remove the nuts from the protection channels.
Move the ramp protection forward from the intake pipe studs and remove it from the engine compartment
Squeeze the fuel pipe tip clamps
Remove the tip of the fuel pipe from the fitting of the fuel rail
Press the spring clip
Disconnect the wiring harness from the injector
We also disconnect the wire blocks from the remaining injectors
We unscrew the two bolts with a head of 8 fastening the fuel rail to the intake pipe
Location of fuel rail mounting bolts
Move the fuel rail along the axes of the injectors and remove the rail together with the injectors
Pry off the retainer with a screwdriver
Remove the nozzle retainer
We take out the nozzle, overcoming the resistance of the sealing ring
Pry off with a thin flat screwdriver and remove the injector O-rings
The nozzle is sealed with two rubber rings: blue - in the fuel rail, black - in the intake pipe.
O-rings are replaceable.
When installing the injectors, apply a thin layer of engine oil to the o-rings.
We assemble and install the fuel rail and all parts in reverse order.
