Pay attention to how the vehicle behaves and specifically the power unit. They will indicate you for problems with nozzles. This can manifest itself in this way:

  • The motor gives a smaller power, the previous overclocking efficiency is not felt.
  • With poor operation of the motor and disadvantage of power, fuel consumption is increasing exactly.
  • Bad start - not a rare symptom of the exit nooks.
  • If the power unit does not keep idle, it can also point to nozzles.
  • Increasing the number of toxic elements in exhaust gases.
  • Increase the revolutions at idle.

Device fuel ramp VAZ 2109

Fuel ramp - Planck, where nozzles are installed. It is fixed on the inlet tube with bolts. To the left of it is located fuel pressure control. It is worth noting that the removal of the fuel ramp is the most problematic phase of cleaning or replacing the nozzles.

How to remove the nozzles of the VAZ 2109 (injector) step by step

Removing the fuel ramp
  1. First of all, it is necessary to remove the fuel ramp.

To remove the fuel ramp you need:

  1. Disconnect the minus terminal from the battery.
  2. In the fuel line, we reset the pressure.
  3. Remove the air filter and disconnect the hose of the inlet tube. Then dismantle the vacuum pressure regulator hose.
  4. Disconnect from the XX sensor the feeding block of the wires. To do this, just press the plastic lock of the pad.
  5. Disconnect the block with wires that go from the nozzles.
  6. Disconnect the fuel and drain hoses from fuel pipes.

  3. We place the sprayer in the container and let them blame for a while.
  4. In parallel, clean the idling regulator using a carburetor cleaner.
  5. Around the nozzle nozzles eating Nagar - Coke. Its consistency is similar to the resin. We have to pick it up and tinker with pollution. This is done outdoor cleaning.
  6. As for the internal cleaning, you will need a pump with a pressure gauge (foot) and a voltage source of 3-12 volts.
  7. In the pump, remove the end of the hose and fill the injection cleaner inside, then we dress the hose on the nozzle.
  8. We pump it up to six atmospheres and supply voltage in three volts. Add power if the nozzle does not click.
  9. Feed electricity is needed by periods, for a short time, while pumping up the pump. In the same way, we pump all fuel sprayers.

The second way.You will need: Sealing ring, pressure gauge, pump, cleaner for carburetor (spray).

Features:

  1. Purifier for the injector change to spray.
  2. We repeat the above activities, only with a carburetor cleaner.
  3. Then we definitely conduct an outdoor stripping devices to remove Nagara.
  4. To do this, apply spray on the clean fabric and process the fuel units.
  5. Thanks to the coke, the coke softened and closes without any problems. You can help yourself with toothpicks or screwdriver.
  6. Before mounting the sprayer in the place of mandatory, lubricate the sealing rings with water and soap.

  3. If we talk about fuel nozzles, then you do not need to change the sealing rings during the replacement of the sprayers if they are in good condition. But if you are going to use them again, the installation is lubricated with the engine oil before mounting.
  4. When the nozzle is dismantled and the rings are replaced (either old left), you can start installing new devices. The procedure is performed in reverse sequence.
  5. Then we insert the sprayer into the hole located on the fuel ramp, and fix the retainer.
