My car won’t start, what should I do?

It can be frustrating and worrisome when your car refuses to start. However, there are several potential reasons why this might be happening, as well as possible solutions to help you get your car up and running again.

Here are some common issues that could be causing your car to not start and what you can do about them:

A flat or faulty battery

Discovering that your car won’t start can be a frustrating experience. There could be several reasons behind this issue, but one of the most common culprits is a flat or faulty battery. Here’s what you can do to troubleshoot and resolve the problem:

Check for Battery Issues

Listen for engine cranking: If you hear the engine turning slowly or failing to start, or if you hear a faint click or complete silence, it indicates a potential battery problem.
Look for battery-related warning lights: Check your dashboard for any battery-related warning lights, such as the battery or charging system indicator.
Inspect the battery connections: Ensure that the battery terminals are clean, tight, and free of corrosion. Loose or dirty connections can prevent the battery from delivering power to the starter motor.

Jumpstart the Car

If you determine that the battery is the issue, you can try jumpstarting the car using jumper cables and another vehicle with a fully charged battery. Follow the proper jumpstarting procedure outlined in your vehicle’s manual.
Be cautious and follow safety guidelines to avoid injury or damage to the vehicles. If you’re unsure about jumpstarting, it’s best to seek assistance from a professional or a breakdown recovery service.

Consider Battery Replacement

If the battery is old (typically around six years) or showing signs of deterioration, it may need to be replaced. Ageing batteries can lose their ability to hold a charge effectively.
Consult your vehicle’s manual for specific battery requirements and consider seeking professional assistance to ensure the correct battery replacement.

Other Potential Causes

If the battery is not the issue or jumpstarting doesn’t solve the problem, there may be other underlying causes, such as a faulty starter motor, alternator, ignition switch, or fuel system issues.
It’s recommended to have a qualified mechanic inspect and diagnose the problem for an accurate resolution.

Remember, safety should always be a priority. If you’re unsure about jumpstarting the car or handling any other aspect of the troubleshooting process, it’s best to consult a professional or contact a roadside assistance service.

They can provide expert guidance and ensure the problem is resolved effectively and safely.

A faulty starter motor 

Check for Battery Issues

Listen for engine cranking: If you hear a loud clicking noise when you try to start your car, it could indicate a problem with the battery or the starter motor.
Check battery connections: Ensure that the battery terminals are clean, tight, and free of corrosion. Loose or dirty connections can prevent the battery from delivering power to the starter motor.
Test the battery: If you have a multimeter or battery tester, you can check the voltage of the battery. A healthy battery should have a voltage of around 12.6 volts or higher.

Assess the Starter Motor

The starter motor is responsible for initiating the engine’s rotation when you turn the ignition key. If the starter motor is faulty, it may prevent the engine from starting.
Signs of a faulty starter motor include a loud clicking noise when you try to start the car or complete silence.
If you suspect a faulty starter motor, it is best to seek professional help as repairing or replacing the starter motor typically requires specialised knowledge and tools.

Try Bump-Starting (Manual Transmission)

If your car has a manual transmission and the starter motor is not working, you can try bump-starting the car with the help of another person or a slight downhill slope.
To bump-start the car, have someone push the car while you’re inside with the ignition in the “on” position and the clutch pedal fully depressed. Once the car gains some momentum, release the clutch quickly to engage the engine, which should start the car.
Note that this method may not work for automatic transmission vehicles.

Seek Professional Assistance

If the above steps do not resolve the issue or if you’re uncertain about the cause of the problem, it’s best to contact a professional mechanic or a roadside assistance service for further diagnosis and assistance.
They have the expertise and proper equipment to diagnose and repair starter motor issues effectively.

Remember, safety should always be a priority. If you’re unsure about jump-starting the car, handling the starter motor, or any other aspect of the troubleshooting process, it’s best to consult a professional or contact your breakdown cover recovery.

They can provide expert guidance and ensure the problem is resolved effectively and safely.

Fuel problems

Check Fuel Levels

Ensure that you have an adequate amount of fuel in your tank. When it’s cold outside, your car requires more fuel to start and run properly. Running low on fuel can cause starting issues, so a simple solution is to top up your fuel tank.

Check the Fuel Filter

A clogged fuel filter can prevent petrol or diesel from reaching the engine, hindering the combustion process required for starting the car.
Consult your vehicle’s handbook for recommended maintenance intervals, as manufacturers typically suggest replacing the fuel filter every two years or between 15,000-20,000 miles.
If you suspect a clogged fuel filter, it’s advisable to have it replaced by a qualified mechanic.

Verify the Fuel Pump

The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump malfunctions, it can result in starting issues.
Signs of a faulty fuel pump may include difficulty starting the engine, sputtering while driving, or a complete failure to start.
If you suspect a faulty fuel pump, it is recommended to have it inspected and repaired by a professional mechanic.

Check for Contaminated Fuel

Contaminated fuel, such as water or debris, can affect the engine’s performance and lead to starting problems.
If you suspect contaminated fuel, you may need to drain the fuel tank and replace it with clean fuel. Consult a mechanic for assistance.

Consult a Professional

If the above steps do not resolve the issue or if you are unsure about diagnosing and resolving fuel-related problems, it’s best to seek assistance from a qualified mechanic or contact a roadside assistance service.
They have the expertise and diagnostic tools to identify and address fuel system issues effectively.

A flooded engine

If your car won’t restart or starts briefly but keeps cutting out, it may be due to a flooded engine. This commonly occurs in older petrol cars when there’s an excessive amount of fuel and insufficient air in the engine, resulting in the spark plugs failing to function properly. Here’s what you can do to address a flooded engine:

Be Patient

Allow a few minutes for the excess fuel to evaporate before attempting to start the engine again.
It’s important to remain patient during this time, as attempting to start the engine immediately may worsen the flooding.

Adjust Starting Procedure

With the gearbox in neutral and the handbrake engaged, press the accelerator pedal fully to the floor and hold it there.
While keeping the accelerator fully depressed, attempt to start the engine.
This technique, known as “clear flood mode,” helps clear the excess fuel from the engine cylinders and allows for better air circulation.

Let the Engine Idle

Once the engine starts, release the accelerator pedal gradually.
Allow the engine to idle for a few seconds to warm up and stabilise before setting off.
This helps ensure that the engine operates smoothly and minimises the chances of it flooding again.

Seek Professional Assistance

If the above steps don’t resolve the issue and your car continues to experience starting problems, it may be necessary to seek assistance from a professional mechanic.
They have the expertise and diagnostic tools to identify the underlying cause of the flooding and perform any necessary repairs.

Remember, safety is paramount. If you are uncertain about handling a flooded engine or any aspect of the starting process, it’s advisable to consult a professional mechanic. They can provide proper guidance and assistance to ensure the problem is resolved safely and effectively.

A faulty key fob

If your car has keyless entry and ignition and fails to start when you push the button, it could be due to a faulty key fob. Here’s what you can do to address this issue:

Replace the key fob battery

If the engine fails to recognise your key or the central locking system doesn’t work, it may indicate a depleted key fob battery.
Replace the battery in your key fob and ensure it is properly seated. This simple step can often resolve the problem.

Start the car with a dead key fob

In some cases, you may be able to start your car even with a dead key fob battery.
Hold the key fob against the start button while pressing it to establish a closer connection, which can sometimes activate the ignition.

Check for a faulty key fob

If the key fob battery replacement or repositioning doesn’t resolve the issue, it’s possible that the key fob itself is faulty.
Contact your dealer or a qualified professional for assistance with diagnosing and potentially replacing the faulty key fob.

Additionally, if you’re unable to turn the key in the ignition, the steering wheel may be locked. To address this, try the following:

Slowly pull the steering wheel to the left and right while carefully turning the key in the ignition.
This action helps release any tension on the steering wheel lock mechanism, allowing you to turn the key and start the car.

If the above steps don’t resolve the problem, it’s advisable to consult a professional mechanic or contact your car manufacturer’s customer support for further assistance. They can provide expert guidance and help diagnose any underlying issues preventing your car from starting.

Cold weather

If you’re experiencing difficulty starting your car during cold weather or after it has been exposed to snow, it could be due to a frozen fuel line or damp spark plugs. Here’s what you can do to address these issues:

Frozen fuel line

In cold weather, water can accumulate and freeze in the fuel line, particularly when the tank is low on fuel.
To prevent this from happening, it is recommended to keep your fuel tank at least half full during winter months.
If you suspect a frozen fuel line, try parking your car in a warmer environment such as a garage or using a fuel-line antifreeze product to thaw the line.

Damp spark plugs

Moisture can build up on the spark plugs, making it difficult for them to ignite the fuel and start the engine.
If you suspect damp spark plugs, you can try removing them and drying them using a cloth or compressed air.
Alternatively, you can let the engine run for a few minutes to generate heat and help evaporate the moisture.

Seek professional assistance

If you’re unsure about the cause of the problem or if the above steps do not resolve the issue, it is recommended to consult a mechanic.
A mechanic can diagnose the specific issue and provide the necessary repairs or maintenance to get your car running smoothly again.
If needed, contact your car insurance provider to inquire about any coverage or roadside assistance services that may be available to help with the situation.

Remember, regular car maintenance and preparation for winter conditions can help prevent these issues from occurring. It’s a good idea to schedule regular check-ups and follow recommended maintenance guidelines to ensure your car remains in optimal condition throughout the year.

Frequently asked questions

What’s the most common cause of vehicle breakdown?

The most common reason for vehicle breakdowns is a flat battery. While there are various factors that can lead to a flat battery, the primary cause is often human error. This includes leaving the lights or radio on for an extended period or neglecting to start the car for an extended period, such as when it has been parked for months.

A flat battery can be an inconvenience, especially when you’re in a rush or far from assistance. It’s important to take precautions to avoid this common issue, such as ensuring all lights and electronics are turned off when exiting the vehicle and regularly starting the car if it’s not being used frequently.

If you find yourself with a flat battery, the most common solution is jump-starting the vehicle using jumper cables and another vehicle with a functional battery. Alternatively, you can seek the help of a breakdown service provider who can assist you in jump-starting your vehicle or provide battery replacement if needed.

Remember, regular maintenance and taking simple precautions can go a long way in preventing a flat battery and reducing the likelihood of experiencing a vehicle breakdown.

Can I call out assistance if I don’t have breakdown cover?

If you find yourself in a situation where your car won’t start and you don’t have breakdown cover, you can still seek roadside assistance. However, it’s important to note that without breakdown insurance, you may be faced with a substantial bill for the services rendered.

Having the appropriate breakdown cover in place offers you peace of mind, knowing that you are protected in case of unexpected vehicle breakdowns. Breakdown cover typically includes services such as roadside assistance, recovery, and even onward travel options to ensure you’re not left stranded.

Investing in breakdown cover can save you from potentially significant expenses and the stress of finding assistance during an inconvenient breakdown situation. It provides reassurance that help is just a phone call away and that trained professionals will be there to assist you promptly.

Before making a decision, it’s advisable to compare breakdown cover options to find a policy that suits your needs and budget. Comparoo can help you explore various breakdown cover options and find the right one for you.

What tools should I carry in my car in case I break down?

Being prepared for a breakdown can save you time and hassle when faced with unexpected car troubles. Here are some essential tools and items we recommend keeping in your car:

Jump leads: Carrying a set of jump leads allows you to jump-start your vehicle if the battery dies. This can come in handy if you or another motorist is available to provide assistance.
Tyre jack and spare tyre: A tyre puncture or blowout can leave you stranded on the side of the road. Having a tyre jack and a fully inflated spare tyre enables you to change the tyre and continue your journey safely. Make sure you also have a lug wrench or tyre iron to remove and tighten the wheel nuts.
Empty fuel can: Running out of fuel can be a frustrating experience. Keeping an empty fuel can in your car allows you to safely transport fuel from a petrol station to your vehicle in case you run out of petrol.
Torch and reflective warning sign: If you break down at night or in low visibility conditions, having a torch and reflective warning sign can help make you more visible to other drivers and aid in your safety while inspecting or working on your vehicle.
Basic toolkit: A basic toolkit with essential tools like screwdrivers, pliers, adjustable wrench, and a socket set can assist with minor repairs or adjustments if needed.
First aid kit: In case of any minor injuries or medical emergencies, having a well-stocked first aid kit in your car is always a good idea.

It’s important to note that while having these tools can be helpful, it’s equally important to prioritise your safety. If you’re unsure about how to use any of the tools or if the breakdown situation requires professional assistance, it’s best to contact a breakdown recovery service or seek help from trained professionals.

Remember to regularly check and maintain your toolkit and replace any expired or damaged items to ensure they are ready for use when needed.
