Disconnect the high voltage wire from the ignition coil.
Turn on starter. On a cold engine (when the coolant temperature is less than 30°С) the control lamp should light up for 1-8 s.
Note. If the test is performed at a higher temperature than that marked on the case of the thermal time relay, the control lamp does not light up.
Check the quality of fuel atomization by the starting injector. To do this, remove the starting nozzle without disconnecting the block and fuel line from it, and place it in a beaker.
Turn on the starter for 1-8 seconds: the starting nozzle should spray fuel in the shape of a regular cone.
