Toyota does not turn starter

The reasons why the Toyota starter does not turn can be very diverse, and this breakdown itself is very unpleasant for the owner, since it does not allow the engine to start. The starter motor may not start at all, or it may turn on, but not have enough power to start the crankshaft. The result is always the same: the inability to move.

Does not turn on

  • Complete absence or insufficiently good contact in the circuit;
  • The starter retractor relay has broken;
  • Malfunctions in the functioning of the contacts of the ignition switch;
  • Stiff drive
  • Starter clutch slips.

Clicks, but does not start the crankshaft

  • Starter brushes or bushings are worn out;
  • Starter windings shorted or broken.

Crankshaft rotation is too slow, due to which the internal combustion engine does not start

  • The viscosity level of the engine oil does not correspond to the temperature regime;
  • The battery is discharged;
  • Insufficiently good brush contact or lack thereof;
  • Poor tightening of cable lugs leading to the starter.
