Car won't start: separate no-crank from crank-no-start

A safe, explainable diagnostic path for one of the most common vehicle symptoms.

What happens when you turn the key or press Start matters. Silence, a click, slow cranking and normal cranking point to different systems.

What this experience provides

  • No crank: verify battery voltage, terminal condition, interlocks and starter circuit.
  • Slow crank: suspect low battery charge, poor connections or starter load after testing.
  • Crank-no-start: fuel, ignition, compression, immobilizer and sensor inputs require testing.
