What Would Cause A Honda Civic To Not Start?

Wondering why is my Honda Civic not starting. Check my guide to know what causes

Some people might find it difficult to believe that a car as aesthetically appealing and sporty as a Honda Civic would have some problems.

However, we know that every car experiences ups and downs in its journey if the car is not maintained well.

Your Honda Civic might not start due to the some problems I have discussed below.

I have conducted ample research on this topic to prevent that from happening and make the situation easy for you to tackle.

1: Low Charge In Battery

Knowing that Honda Civic is known for its internal and external components or accessories, one might think its battery would have a long life span.

However, research has been conducted on this, implying that the latest batteries have a shorter life span.

There are many causes of a low charge in the battery. The most common cause is the weather.

During extreme weather conditions, the battery has to produce and supply much more power, which tends to exhaust after a few hours.

Moreover, the chances of corrosion in the positive plates are also high. The indication of a low charge in the battery can be provided by your car in many ways.

In most cases, other important components stop functioning as they are directly associated with the car’s battery. You might also see multiple warning signs on the check engine light.

What Should You Do About It?

  • Use a voltmeter to see how much voltage is being supplied to the engine by the battery of your Honda Civic.
  • The voltmeter reading must not be lower than 12 volts because that would indicate that the battery is producing a low charge.
  • You can also jump-start your car in this case but make sure you do not do it yourself because Honda Civic is a delicate car.
  • Getting a new battery or a refurbished one is also an option.

2: Alternator Failure

We all know how valuable alternators are for every vehicle. The same is true for the Honda Civic as well. You must ensure that your alternators are in excellent shape.

If the alternators fail, the car’s brain, which is its engine, will fail as well. These two are inextricably linked. You can’t run anything if it is not supplied with the necessary energy.

Alternators in cars are essential because they supply electricity to our vehicles’ engines.

Your alternator can only become a problem after driving the car for more than 2500,000 miles. This is because alternators are specifically designed to last for a long time.

The process goes on by your alternator producing the charge and providing it to the battery.

The battery consumes the charge to send the power or energy to the car’s engine, which starts the car. An alternator failure can be very expensive to maintain.

What Should You Do About It?

  • Firstly, if it has been more than five years, you need to change the battery and bring in a new battery. Once you have a new battery, you need to give it time before it starts working effectively.
  • You can purchase a voltmeter and see if your batter is getting at least 12 volts of charge. If that is not the case and it shows a lower charge, you can invest in a new battery.
  • Provide a jumpstart to your battery. You give it a strong electrical charge to provide it with enough voltage. It is like bringing a patient back from a coma.

3: Broken Starter Motor

The starter motor of a car is a very important component. This component is what a vehicle uses to start the car. The entire combustion system starts when the starter of a car is engaged.

Your car will not operate successfully if the starting motor is defective. This might leave you stuck and cost you a small fee to get your vehicle back on track.

If you twist the ignition key and nothing occurs, this must be the clearest sign that you have a starting motor problem.

The engine may create a clanging noise or remain entirely quiet.

When you turn the key, you may hear a grinding noise in the starter. This might be due to a faulty starting motor or a faulty circuit.

A broken starter motor is like broken buttons because if you have to start a particular system, you cannot do it without the important buttons.

You must consider the following solutions to fix the starter motor of your Honda Civic.

What Should You Do About It?

  • Analyze whether there are any signs of corrosion near the components of your starter. If so, clean those parts in the most efficient way possible.
  • Getting a new starter for any other car might not be expensive, but everything is expensive if you are buying it for Honda Civic. Consider buying a refurbished starter for your Civic.
  • The flywheel attached to the starter needs to be well maintained as it can directly impact a starter’s performance.

4: Blocked Fuel Line

A fuel line is a faucet installed in a car’s engine. It regulates and manages the amount of liquid hydrogen or fuel vapor.

A fuel line, an essential component of the fuel injection system, is typically made up of all the pipes that emerge from the filter neck.

It is the link between the carbon canister and the fuel tank. The fuel line is entirely contained within the engine.

When there is a clog, fuel leaves the canister but does not reach the engine since the route to the engine—the fuel line—is congested.

If this occurs, the engine will typically not start until the problem is resolved.

If your Honda Civic, every once in a while, fails to start, screeches, or tends to start and then shuts down, you may have a blockage in the fuel system.

You must cater to this situation with utmost priority.

This is because if the leakage causes the fuel to reach the ignition system, it might lead to smoke coming out of the car and eventually setting the car on fire.

What Should You Do About It?

  • Make sure to check for holes in the fuel transmission lines. It would be easier to see the leakages.
  • Ensure the fuel filter is clean and no contaminants like dust or debris stop adequate fuel from being supplied.
  • Replace the fuel filter every once in a while when the performance of your car’s engine seems to be compromised.

5: Damaged Spark Plugs

Spark plugs are critical engine components that generate electric sparks to activate the fuel-air combination in the combustion chambers and generate energy.

They are an important part of the ignition system because they aid the engine with functioning by continuously detonating the fuel-air mixture.

Spark plugs have a finite lifespan beyond which they become faulty. Sometimes, even before their lifespan ends, spark plugs might stop functioning.

Your spark plug damage might not sound like a serious issue, but the series of issues it brings must be avoided.

It would decrease the fuel economy of your Honda Civic to a great extent. This also impacts the battery of your car.

The battery would have to produce twice as much charge or energy to supply to your engine, which can eventually exhaust it.

If the whole combustion system were kept on hold because of small damaged spark plugs, then there would be no point in discussing other issues.

What Should You Do About It?

  • If you have used your Honda Civic for more than 30,000 miles to 35,000 miles, you must consider getting new spark plugs for the car.
  • In case you want to replace the spark plugs, it would cost you somewhere between $150 to $200.
  • Please ensure that if the spark plugs are not of supreme quality, do not fall into the scam of purchasing them.
