Starting & electrical

Starter spins but the engine does not turn

A fast whirring or grinding when you turn the key normally means the starter is running but not engaging with the flywheel.

Symptoms drivers describe

  • High-pitched whirring with no cranking
  • Grinding or crunching when starting
  • Occasionally starts, then whirrs the next time

Possible causes

  • A worn starter pinion or one-way clutch
  • Damaged flywheel or flexplate teeth
  • A sticking starter solenoid
  • Loose starter mounting bolts

What you can do

  • Avoid repeated attempts — they can damage more flywheel teeth
  • Note whether it engages if you try again later

How we check it in the workshop

We test the starter circuit, remove the starter where needed and inspect the pinion and flywheel teeth before quoting.

Is it safe to keep driving?

The car may not start reliably. If it is stranded we can recover it to the workshop.
