If your car won’t start, it means the engine isn’t turning over or firing up. This can be caused by electrical faults, fuel delivery problems, or mechanical failures. Since a non-starting car leaves you stranded, it’s important to identify the cause quickly and get it repaired.

What does it mean if a car won’t start?

A no-start condition means the starter motor, fuel system, ignition system, or battery isn’t working properly. Sometimes you’ll hear clicking, cranking without firing, or nothing at all when you turn the key or press the start button.

Common causes of a car not starting

• Flat or weak battery
• Faulty starter motor or solenoid
• Alternator failure (battery not charging)
• Empty fuel tank or fuel pump failure
• Blocked fuel filter or faulty injectors
• Worn or fouled spark plugs
• Faulty ignition switch or wiring
• Crankshaft or camshaft sensor failure

Why do you need to fix this problem quickly?

If your car won’t start, you may be left stranded without warning. Ignoring the problem can also lead to further damage — for example, repeatedly trying to crank the engine can drain the battery or damage the starter motor.

How do you know when to get it checked?

Signs include:

• Clicking noise when turning the key
• Engine cranks but won’t fire
• No sound or response at all when starting
• Dashboard lights flicker or stay dim
• Check Engine Light or battery warning light illuminated

What happens during an assessment?

A mechanic will:

1. Test the battery and charging system
2. Check starter motor operation
3. Inspect ignition system components (plugs, coils, wiring)
4. Check fuel system (pump, injectors, filter)
5. Scan ECU for fault codes
6. Diagnose and recommend the correct repair

How much does it cost to fix?

Costs vary depending on the cause. A new battery may cost $200–$450. Starter motor replacement ranges from $580–$1,000+. Fuel or ignition system repairs can range from $300–$1,200+.

Is it unsafe to drive if the car won’t start?

You won’t be able to drive at all if your car doesn’t start. If the issue is intermittent, the car may leave you stranded unexpectedly, which is unsafe. The problem should be diagnosed and fixed as soon as possible.
