Checking the starter injector
1 - starting nozzle; 2 - Torx bolt
Correct location of the connector and hoses
1 - starting nozzle; 2, 3 – connector; 4 - hoses
A faulty starter injector makes it difficult to start the engine, impairs transient performance, and increases fuel consumption.
Checking the starting injector is carried out on a cold engine.
Examination
1. Remove the wire connector from the starter injector.
2. Unscrew the 2 mounting bolts and remove the injector without disconnecting the fuel hose from it.
3. Connect the auxiliary air damper connector to the starting injector.
4. Close the circuit of the speed control relay, for which use an additional wire with a 16 amp fuse, remove the speed control relay and close terminals 30 and 87.
5. Insert the starting nozzle into the glass vessel and turn on the starter. When the starting nozzle is in good condition, fuel should be evenly sprayed from it.
6. Turn off the starter, remove the starting nozzle from the glass container and wipe it dry. At the same time, no fuel should appear from the atomizer within 1 minute.
7. In case of uneven fuel atomization and leakage, the starting nozzle must be replaced.
