Turn the engine switch to the ON position and check the operation of the glow indicator lamp in the
combination meter.

[Point 31
Check the operation of the preheating timer
The power supply time for the glow plugs is determined in accordance with the engine coolant
temperature. If the power supply time is extremely short it can cause a starting defect.
[Point 41
Check the injection timing of the injection pump
When trying to detect the probable cause, it is unlikely that a malfunction in only one of the cylinders would
cause a starting defect. For this reason, perform an injection timing inspection before performing an
individual nozzle inspection or compression inspection.
[Point 51
Check the operation of the injection pump solenoid
Put your hand on the solenoid body and check whether or not the internal plunger moves in parallel with
turning the engine switch ON and OFF.
