Car won't start — possible causes and what to do

When a car won't start, the first step is to notice exactly what happens: the starter doesn't crank at all, cranks slowly, or cranks normally but the engine doesn't fire. Each symptom points to a different system.

Possible causes

  • Flat or ageing battery
  • Corroded battery terminals or a poor earth connection
  • Faulty starter motor or starter relay
  • Fuel supply or ignition problem
  • Immobiliser or key recognition fault

What you can safely check yourself

  • Whether dashboard lights and headlights are bright or dim
  • Whether you hear a click, slow cranking or nothing when turning the key
  • That there is fuel in the tank and the key fob battery isn't flat

When to call a mechanic

If the car still won't start after simple checks, don't keep cranking — it drains the battery and can damage the starter. Don't work on the fuel system yourself.

How MobilaisServiss can help

A mechanic comes to your car, tests the battery, charging and starter, and where possible starts the car or repairs it on site. Daily call-outs in Riga and the surrounding area, elsewhere in Latvia by arrangement.

This is a general guide, not a diagnosis. The exact cause can only be confirmed after inspecting the car.
