6.8. Check and replacement of atomizers

Check on the car

1. Check up work of atomizers as a stethoscope. Be convinced that frequency of operation of atomizers raises with increase in turns of the engine.
2. If clicks are listened badly more exact check is provided with the light indicator. If the indicator is shone, but clicks are not present, the atomizer is faulty.
3. Check up resistance of an atomizer, having disconnected a socket. If resistance of an atomizer does not correspond to norm an atomizer replace.

Bench (imitating) tests of atomizers

These tests are carried out only in car-care centre as the special equipment is required.


1. Open the main socket of conducting of atomizers and remove soaking up collector (subsection 3.1.6 see).
2. Disconnect from a regulator of pressure of fuel hoses and turn away bolts of fastening of a regulator.
3. Disconnect from atomizers sockets and remove atomizers.
4. Installation is carried out upside-down. Replace ring linings. Before engine start-up restore pressure of fuel, having inserted into place a safety lock of the pump and having included ignition.
