Removing the ramp and injectors of the Lada Granta engine
We remove the ramp and fuel injectors to check cleaning, replacement, and also when removing the intake pipe
Before removing the fuel line, relieve the pressure in the fuel system.
Remove the fuel pump power circuit fuse
Start the engine and wait until it stalls. After that, turn off the ignition and put the fuse in place.
Disconnect the negative terminal of the battery
Remove the air supply hose to the throttle body
Use a flat-head screwdriver to press out the clamp of the engine control system wire block
Disconnect the block from the injector wire block
Use two 17mm wrenches to unscrew the fuel rail fitting from the tip of the fuel supply hose to the rail
Remove the tip of the fuel supply hose from the ramp tube
The connection is sealed with a rubber ring
Remove the throttle assembly (described in the article - Removing and installing the Lada Granta receiver)
Using a 5mm hex wrench, unscrew the screw securing the ramp to the inlet pipe on the left side
Use the same key to unscrew the ramp fastening screw on the right side
By pulling the ramp along the axes of the injectors and overcoming the resistance of the rubber sealing rings of the injectors, we remove the four injectors from the holes in the intake pipe
We take out the fuel rail assembly with injectors to the left side of the car and remove it from the engine compartment
The picture shows the fuel rail assembly with injectors and wiring harness
Compress the spring clamp boats of wires, disconnect the block from the injector connector
We also disconnect the pads from the connectors of other injectors
Use a screwdriver to pry the bracket that secures the injector onto the ramp
Remove the bracket
Overcoming the resistance of the rubber o-ring, remove the nozzle from the ramp pipe
Using the blade of a flat-head screwdriver, remove the rubber o-rings of the injector
We also remove other injectors.
To identify a faulty injector, connect a tester to the injector contacts in ohmmeter mode.
It should show a resistance of 11-15 Ohms
If the winding resistance is not normal, replace the nozzle.
Replace the injector O-rings with new ones.
Before installing the injectors, apply a thin layer of engine oil to the sealing rings.
We assemble and install the injectors and ramp in the reverse order.
Ramp bolt tightening torque 9-14 Nm
Tightening torque of the fuel hose fitting is 210-34 Nm.
After installing the ramp and injectors, you need to check the tightness of the connection of the pipeline and the injector seals.
