Why Won’t My Car Start? Assuming you have ruled out that the problem is with the battery, there are a few things that could be causing your car not to start. It could be an issue with the starter, the ignition, or a clogged fuel line. If you’re not sure what the problem is, it’s best to take it to a mechanic to get it checked out.

Why Won’t My Car Start?

1. Dead battery

Your car won’t turn on. The most common reason is a dead battery. The car’s battery supplies electrical power to all electrical components and the whole car ( Lights, radio, etc.). The alternator charges the car’s battery while it is running. The storm must be set enough to allow you to start the vehicle and use electrical components.

There are many reasons why your battery might die.

You left your dome or headlights on overnight or too long.

A loose wire is your problem.

The water caused poor conductivity in the component.

The battery’s life expectancy has ended.

Some of the most common symptoms are:

  • All of the electrical components (e.g. The lights, radios, etc. ).
  • The battery light is on.

Jump starting your car is one way to test if the problem battery. If your jump-start fails, you likely have a dead battery or an alternator having difficulty charging the battery.

You can replace the battery, or alternator, clean the connections or have a technician perform the service.

Incorrect ignition switch

2. Incorrect ignition switch

If your battery works properly, you might have an ignition switch problem, but your car won’t start after a few attempts. Turning on your headlights can help you pinpoint the issue.

Your car’s battery controls your dashboard and headlights. If they don’t turn on, your engine won’t start. A bad ignition switch could be the culprit.

3. Starter problems

Another reason why your car won’t turn on is a bad starter. The starter is an electrical motor connected to the battery. It is responsible for setting the engine (i.e., pistons, crankshaft, etc.) When you turn on the ignition switch, the engine will start.

The starter is done once the engine is started and in motion. The starter can fail to turn on the ignition key or cause the motor not to crank correctly. A damaged or weak starter may cause your car not to start. This sounds very similar to the previous bad ignition switch.

Some of the most common symptoms are:

  • The ignition key is not turning enough to start the car.
  • The engine doesn’t start but you can hear a clicking sound as you turn the ignition key.
  • It is very noisy trying to turn the car on.

4. Fuel filter clogged

The gasoline won’t reach the engine if the fuel filter is blocked. It makes it more difficult for your car’s fuel pump to work correctly. It would help if you changed your fuel filters every 15,000 to 22,000 km.

5. Gas tank empty

It’s possible to feel silly if your car won’t start, but this happens more often than you might think. It’s easy to forget to fill up your gas tank when you drive around constantly. There is an easy solution: get more gas!

6. Alternator

A malfunctioning alternator could mean your battery isn’t being charged. You can start looking for a worn or slipping belt if you suspect your alternator is the problem. A warning flash of light will be given if the belt is worn or breaks. This warning might not be given if the system output is defective.

It is easy to check if the gauge on your car’s instrument panel is present. Check to see if your instrument panel displays approximately 14 volts. Modern vehicles don’t have an alternator gauge. You might need a mechanic or technician to inspect the car.

Other warning signs include a weak cranking start or dimming headlights.

7. Spark Plugs

Secondary ignition problems are rare nowadays. These problems can cause your vehicle to not start on rare occasions.

For an automobile to reach 100,000 miles, it was necessary to be maintained three decades ago. Due to the long replacement times for spark plugs and the fact that most car owners don’t keep their vehicle for its entire useful life, it is easy to forget about replacements for long-lasting parts such as spark plugs. This can lead to car-start problems.

8. Locked steering wheel

Sometimes the key won’t turn when you turn it in the ignition. Anti-theft features feature many cars that lock the steering wheel immediately after taking the key out. If the lock is in place, the revolution will stay in its original position. Turn the key slightly to the left or right to get your car moving.

9. Fuel Pump

Even though there’s nothing to stop the fuel from reaching the combustion chamber, a faulty or insufficient fuel pump can significantly impact the performance of your vehicle.

The carburetor in older vehicles was located below the tank, and gravity was used for fuel supply. Even though these models could not drive over steep hills, failing pumps were not an issue.

Switch the key to the on the side, and listen for the pump running. If your fuel pump does not work, your car is out of fuel.

10. Air Filter

A car must breathe, just like humans. Your car’s filter can accumulate grease, road dust, and muck over time. This will make it difficult for your vehicle to enjoy clean, filtered air.

This buildup can prevent your vehicle from getting the right amount of air. Insufficient air can cause the gas not to ignite and the internal combustion process to remain incomplete.

To solve this problem, you can buy a new cleaner readily available at most automotive supply stores.

Ground Cable Wiring Problem

11. Ground Cable Wiring Problem

The ground cable is a heavy, black cable that connects the car’s negative terminal to its body. You may also call it the ground cable, ground wire or ground strap.

This cable is the base of almost every vehicle’s electrical system component.

It will stop your car’s engine from starting if there is an issue. The power flow will be cut off. This means that your car’s engine won’t turn on.

How can you tell if your ground cable is down?

These are some of the most common symptoms:

  • Dimming or flickering dome lights
  • Defective fuel pump
  • Dead battery
  • Sensor failures may occur occasionally
  • Turning on and off electrical devices
  • The AC compressor is slipping and slipping.
  • Broken cables or throttle
  • It is hard to start

12. Timing Belt Replacement Required

Timing belts are an internal component of the engine. It is a rubber strip that rotates your engine’s crankshaft and cam at the right time.

It will fail, and your car’s engine will stop working.

It is possible to hear the starter motor turn over but not engage or hear a ticking sound under the hood.

This is a less-known problem, but a timing chain can fail while the engine is running, causing engine damage.

What to do if your car won’t start?

1. If the car clicks when you try to start it

Try Cycling the Key

If your car won’t turn on, but it turns on, switch on the dome lamp and observe it while you attempt to start the engine. The light going out means that the battery is almost dead.

The fundamental cycling trick is great for heating the starter, battery terminals, and charger. Turn the key repeatedly to the start position, about 10 times per row.

Wait five minutes before you stop. Next, start the engine. If the dome light stays on when you turn the key, move on to the next step if the car doesn’t start.

Try tapping on the Battery Terminals

If you are stranded with no tools, there is no way to clean the corroded terminals of your battery. You can move the terminals or, at minimum, jar them enough to get better contact. If the car doesn’t start, you can gently smack the terminals with the heel of your shoe. Next, try to start the engine.

Try Tapping the Starter

You can use the tire iron of your car jack to hit the starter motor if you have it. Tap on the contacts to release them from sometimes stuck electrical contacts.

2. If there’s no click when you turn the key, it isn’t clicking

Try Shifting the Shifter

Move the shift lever to neutral and then start the engine. You can move the shift lever back to the park and start it again if it doesn’t work. Sometimes, moving the shifter can reestablish electrical contact within the transmission range selector (also called the neutral safety switch).

If the engine Doesn't Start, But It Cranks

3. If the engine Doesn’t Start, But It Cranks

You can try these tricks if your engine doesn’t crank but doesn’t start.

Try Swapping Relays

Turn the radio off and then listen for a buzzing sound. This is the fuel pump priming your injection system. If there is no sound, it could be that the fuel pump relay is not working correctly or that the pump may have failed.

Locate the fuel pump relay in your owner’s guide or legend for the under-hood fusebox cover. Straighten the fuel pump relay. Locate another relay with the same part number, and replace it with your fuel pump. Insert it directly into the socket. After that, start the engine.

Try Smacking the Fuel tank

Tap the fuel tank with your heel to get your car to start. Next, try to start the vehicle.

Do not flood a flooded engine

The engine may be flooded if you smell gas. Hold the accelerator pedal down and crank the engine.

Try tricking the computer

Vacuum leaks or malfunctioning temperature sensors can cause an air/fuel mixture to be too thin to start a cold engine. If your car doesn’t start after you have tried the other methods, push the accelerator halfway to try starting it. This will tell the computer that you need more fuel.
