You turn the key and nothing happens. Or the starter cranks weakly and then stops. Few situations are as frustrating as a car that refuses to start, especially when you are in a hurry. Before you call a tow truck, here is what you can check on your own.
1. Battery - The Culprit in 60% of Cases
In our workshop, more than half of the cars that come in with a "won't start" problem have a weak or dead battery. The signs are clear: the starter cranks slowly, the dashboard lights are dim, or you hear nothing but a click when you turn the key.
What you can try: If you have jumper cables, connect to another car and try to start. If it fires up, the battery is either drained or at the end of its life. Batteries typically last 4-5 years, so if yours is older than that, it is probably time for a replacement.
Practical tip: In winter, the number of cars with dead batteries at our shop triples. If you know your battery is old, do not wait for it to leave you stranded in the cold.
2. Starter Motor - Click and Silence
If the battery is good (lights work normally, dashboard powers up), but you hear just a single click when you turn the key, the problem is most likely the starter motor.
Old trick: Tap the starter lightly with something while someone turns the key. If the car starts, the starter is on its last legs and needs replacing. This is a temporary fix just to get you to the shop.
3. Fuel Pump - Engine Cranks but Won't Catch
When the starter cranks normally but the engine just will not fire up, fuel may not be reaching the engine. Turn the key to the "on" position (do not crank), wait two seconds, and listen. You should hear a quiet humming from behind the rear seats. If there is no sound, the fuel pump may have failed.
Note: Also check that you have not simply run out of fuel. The fuel gauge is not always accurate, especially on older cars.
4. Spark Plugs - Especially in Damp and Cold Weather
Worn spark plugs can completely prevent the engine from starting. This is a common problem on vehicles that have not been serviced in a long time. In damp weather, even spark plugs that are borderline can fail.
What you can check: If the engine cranks but will not catch, and you smell petrol from the exhaust, fuel is getting through but is not igniting. The spark plugs or ignition coils are the likely suspects.
5. Electronics - On Newer Cars
On newer vehicles, a faulty crankshaft or camshaft position sensor can completely block the engine from starting. The same goes for immobiliser issues: if the key is not recognised, the engine will not start. Without a diagnostic tool, there is not much you can do here.
When to Stop Trying
If after 3-4 attempts the car will not start, stop turning the key. Each attempt drains the battery and can damage the starter. If you smell petrol, definitely stop because you can flood the spark plugs.
Can't Fix It Yourself?
From our experience, diagnosing a starting problem usually takes about an hour. Get in touch or stop by the workshop, and we will quickly figure out what the issue is.
