Car Engine Not Starting? How To Fix it?

Car Engine

You never truly acknowledge how vital something is until the point that it’s gone and this is particularly valid for your vehicle. You use it for driving your children to class, heading to work, getting staple goods, traversing the city, and significantly more.

In the event that you find that your vehicle won’t begin, there are various issues that might be the offender.

So when it quits working out of the blue, it’s a gigantic torment.

There are a ton of reasons why your vehicle won’t begin, yet some are more typical than others. The five essential classes that you should address initially are the battery, fuel conveyance, starter, carburetor and Clogged fuel filter. also, that Odds are that if your vehicle won’t begin, the issue lies some place inside that short rundown. Begin narrowing down conceivable issues so as to figure out what you have to do so as to fix the vehicle.

There are things an engine needs to start and run properly

1. A BATTERY with enough power to turn the engine over fast enough to start

A dead battery is the most common reason why your car won’t start. The battery is what the car uses to provide electrical power to the entire car and electrical components (e.g. lights, radio, etc.). While the vehicle is running, the alternator charges the battery. If the battery is not charged sufficiently, you will not be able to start the car or use any electrical components.

Your battery can die for a variety of reasons:

  • Your headlights or dome light was left on overnight or for too long
  • You have a loose wire
  • The water inside the component evaporated, leading to poor conductivity
  • The battery’s lifespan has expired

Some common symptoms include:

  • None of the electrical components work (e.g. the lights, radio, etc.).
  • Battery light is on.
  •  

One way you can test to see if the battery is the problem by jump starting your car. If the jump start works, you’re most likely dealing with a dying battery or an alternator that is just having trouble recharging the battery. Consider replacing the battery or alternator, cleaning the connections, or having a technician do the service for you.

2. A good STARTER strong enough to turn the engine over fast enough to start

A broken starter is another common reason your car won’t start. A starter is an electrical motor that is connected to the battery. It’s role is to set the engine (i.e. pistons, crankshaft, etc.) in motion when you turn the ignition switch on. Once the engine starts and is in motion, the starter’s job is complete. If the starter goes bad, the engine will not crank properly or may not crank at all when you turn the ignition key on. If you hear a clicking noise when you try to start your vehicle, a broken or weakened starter could be the reason why your car isn’t starting. This is very similar to the bad ignition switch example listed before.

Some common symptoms include:

  • Car is not starting when turning the ignition key.
  • Hear a loud clicking sound when turning the ignition key, but the engine does not start.
  • Very noisy when trying to turn on your car.

3. Proper fuel delivered to engine cant passed the fuel filter . No fuel, no start

If your fuel filter is clogged, the gasoline won’t be able to reach the engine. This makes it difficult for your car to burn the fuel it needs to get going. Fuel filters should be changed every 15,000 to 20,000 kilometres, so consider swapping fuel filters next time you get your car serviced.

4. Proper fuel air mixture delivered to engine by the CARBURETOR or FUEL INJECTION SYSTEM.

A carburetor works by the VENTURI PRINCIPLE. If you pass air across a hole, a vacuum will be created in that hole. A carburetor has many carefully positioned holes which the air sucked in by the engine flows past. These holes are connected to the CARBURETOR BOWL, which is kept full of fuel by a FLOAT AND NEEDLE VALVE.

This valve and float shut off the pressurized fuel sent from the tank by the fuel pump. It works about the same way as a toilet tank float valve. How much air flows by the carburetor venturi’s is determined by the throttle plate, which restricts the airflow through the carburetor. At wide open throttle, all possible air is admitted throught he carburetor, and maximum power is gotten from the engine.

When an engine is cold it needs a richer (more fuel to air mix than usual) mixture to run correctly. A carburetor has a device called a CHOKE to accomplish this. The choke is like the throttle, except it is on the top rather than the bottom of the carb, and it closes when cold and opens when warm. When the choke is closed, it restricts the air entering the carburetor at the top, while the throttle still allows the same amount of air to go through the bottom.

This means the same amount of fuel is sucked, but less air: so the mix is richer. Most carburetors have a vacuum “motor” (that is, a diaphragm moved by vacuum) that is connected to a rod that pulls the choke open a bit after the engine starts. This is called a “CHOKE PULLOFF”. This enables the choke to be fully closed and provide a super rich mixture to start the engine. Once the engine starts, the choke pulloff opens the choke a bit to let the engine “get some air”. If your car runs great when warmed up, but smokes black and hardly runs when you first start it, you may have a bad choke pulloff.

The FUEL INJECTION PUMP, FUEL FILTER, COMPUTER, AND ALL ITS SENSORS AND WIRING can make the fuel injection system fail. Individual injectors can become clogged with rust, varnish, etc. All systems have a pressure regulator, since fuel injection systems rely on very constant and accurate fuel pressure to operate properly. If the pressure is too high, the car will run rich.(Black smoke!) If pressure is too low, the engine will run lean or will not run at all! (Maybe the most common gasoline fuel injection problem is a bad fuel injeciton pump!)

5. Proper spark of high enough voltage across good SPARK PLUGS. No spark, no start .

Your spark plugs ignite the compressed fuel/air mixture in your engine. This then powers your car down the road.

Spark plugs last longer today than they used to, however plugs still should be checked every 10,000 to 20,000 miles or so. Some manufacturers recommend replacing plugs at an even longer interval: many recommend 50,000, even 100,000 miles before replacement. These plugs may last that long, but GOOD LUCK getting them out of an aluminum cylinder head after 100,000 miles!

With today’s electronic ignition your plugs can be worn out and your engine still run fairly well. On the flip side, if your engine isn’t running right, chances are just a new set of plugs aren’t going to help anything. I say this because today a “tuneup” basically consists of replacing the plugs. Period. I’ve worked on a lot of cars where the customer has had 3 tuneups in the past year to fix a rough run situation and has only gotten 3 new sets of plugs. The problem lay in a computer sensor or some such thing.

Most engines (except diesels) use an electric spark to ignite a fuel/air mixture. The fuel burns and powers the car. This electric spark has to happen at exactly the right time or the engine will not run properly. This is called “Ignition Timing”. When a mechanic “Sets your timing” during a tuneup he is adjusting your ignition system to fire the plugs at the proper time.

Your ignition timing changes as you drive. The number of degrees BEFORE TOP DEAD CENTER (BTDC) is called the ADVANCE. This is done mechanically (centrifugal advance), or by vacuum (vacuum advance), or by computer, or by a combination of these. Whatever the setup, advance increases with engine RPM and decreases as the engine goes under a load.

Then how to prevent the Car Engine not starting and also maintain your car?

Vehicle Maintenance

To maximize the life and performance of your vehicle, here is a list of items you should check depending on the time and season. Some of these parts of your vehicle should be checked regularly, and others only in the long run. Be sure to follow your vehicle’s maintenance schedule and service interval record.

Caring for your car and keeping it in proper running order takes a little bit of effort, but you definitely don’t have to be a mechanical whiz to keep your vehicle running well. The biggest hurdle is being aware of what needs to be done—and how often—for optimal vehicle upkeep. By knowing the basics about what your car needs, and when you should perform routine car maintenance, you’ll ensure that your car is in top-running condition.

As an added bonus, if you can prove that your vehicle has been well maintained, you’ll be able to ask top dollar when it’s time to resell it. And, of course, it’s important to remember that car maintenance costs, while not always cheap, can ultimately help you avoid expensive repairs down the road.

To make it easy to keep track of your car maintenance schedule, we’ve created a simple, downloadable car maintenance checklist to help you keep on top of your automotive maintenance.

SHORT TERM CHECK-UPS

For proper vehicle maintenance, inspect the following:

OIL AND COOLANT LEVELS

Every month, or every few gas fill-ups and especially before any longer road trips, it’s a good idea to get under the hood of your car and inspect both the oil and coolant levels while the engine is cool. Low levels of either can lead to engine problems if left unchecked. Refer to your owner’s manual to locate both on your specific vehicle.

AIR FILTER

Your engine’s air filter is what regulates the air that flows into your engine and helps keep out debris and particulate. By making certain that your air filter is flowing properly, you can improve your fuel efficiency, decrease your emissions, and help ensure the life of your engine. This can be done easily at home, so check your owner’s manual for instructions and how often it needs to be changed.

TIRE PRESSURE AND TREAD DEPTH

Since well-maintained tires are integral to a safe, fuel-efficient ride, make it a habit to visually inspect your tires often. Check the pressure in your tires every month, and before long trips or carrying extra load. Don’t forget the spare. A tire pressure gauge will be needed to check your tire pressure. Also, during the colder months, note that tire pressure drops one pound with every 10 degree decrease in pressure. Your owner’s manual will tell you how much air pressure your tire needs. You can check your tread depth using the simple penny method.

HEADLIGHTS, TURN SIGNALS, BRAKE, AND PARKING LIGHTS

It’s important that the lights on your vehicle are properly functioning, but oftentimes it can be easy item to overlook. Once a month, turn on your headlights when you’re parked in front of a flat surface and check that both headlights are working properly and well-positioned. Walk around your car and visually inspect both turn signals and your parking lights. Have a friend stand behind the car while you engage the brakes to be certain that your brake lights are functional.

OIL & FILTER

The motor oil in your vehicle’s engine serves a whole slew of functions: it lubricates the moving parts, helps act as a sealant against debris, cools the engine, reduces wear and tear, and helps prevent engine corrosion. Keeping it clean is vital for good engine health. Depending on your car and what kind of oil you’re using, you may need to change both the oil & oil filter as much as every 3 months or 3000 miles. Many newer vehicles’ owners’ manuals will recommend changing your oil less frequently – often in-between 5,000 and 10,000 miles. Check your vehicle owner’s manual and consult with a professional to be certain what is appropriate for your vehicle.

ROTATE TIRES

Depending on your vehicle alignment, usage, and many other factors, the tread wear patterns on your tires may vary between the front and back tires, or even from one side of the tread to the other. Rotating your tires will help to extend the service life of your tires by more evenly balancing the tread wear, and helping prevent noise and vibration problems.

WAX VEHICLE

Making certain to wax your vehicle every six months after washing it won’t just keep it shiny, it’ll also help to keep both the paint in good shape and reduce the chance of rust. Many irritants such as dust, sand, and salt can build up and environmental factors like ozone and ultraviolet light can cause microscopic damage, but waxing can help minimize this by forming a protective seal to extend your paint’s life.

LONG TERM CHECK-UPS

TRANSMISSION FLUID

Much like the oil in your engine, transmission fluid is a lubricant that helps keep all of the moving parts inside of your transmission functioning properly. Whether you’re driving an automatic or manual transmission vehicle, it is essential that you have your transmission fluid checked and changed when needed to avoid costly transmission damage or replacement. Follow the vehicle manufacturer’s recommendations.

TRANSFER CASE FLUID

In four-wheel or all-wheel drive vehicles, the transfer case is what shifts power from the transmission to the axles. You’ll need to have the transfer case fluid checked according to the vehicle manufacturer recommendations to make certain that it is properly filled and leak-free. This will require you getting under the vehicle, so bringing it into a professional is recommended.

INSPECT SHOCKS AND STRUTS

The shocks and struts on your car function to control the impact and rebound as your vehicle passes over bumps in the road and are an essential part of your auto’s steering system. They should be inspected by a professional every 50,000 miles or bring your car in to the shop if you notice a decrease in smoothness or loss of control when driving.

COOLANT FLUID EXCHANGE

The radiator in your car is a vital component that helps keep your engine cool and functioning properly. Having your coolant system flushed regularly will help get rid of contaminants that can build up inside as well as ensure that your radiator is filled to a proper level. Check your vehicle manufacturer’s recommendation to find out how often your coolant should be exchanged,

SPARK PLUGS

The spark plugs in your engine ignite the gas and air mixture that ultimately powers your vehicle . If your spark plugs aren’t functioning properly, your engine will lose power and won’t run at optimal capacity. Have a professional check and replace any faulty spark plugs depending on vehicle mfr recommendations or when you feel a decrease in your engine’s power.

SERPENTINE BELT

Although may seem like a simple piece of rubber, your vehicle’s serpentine belt is essential to keeping your car running by powering peripheral devices such as your alternator, power steering pump, and air conditioner compressor. Visually inspect the belt to ensure that it is free of cracks or other wear and tear. Replace id damaged or according to your vehicle manufacture’s recommendation.

FRONT AND/OR REAR DIFFERENTIAL

The differentials are devices that split the torque—or power—from the engine and allow it to send power to the tires. In front or rear-wheel drive vehicles, there is only one differential, but in 4-wheel and all-wheel drive vehicles, there is both a front and rear differential, and possibly even a center differential. Like many parts of your vehicle, the differentials need to be kept lubricated to ensure proper functionality. Have a professional check and change fluid whenever your vehicle manufacturer recommends it.

SEASONAL CHECK-UPS

The needs of your vehicle can vary by season and driving conditions. Following are a few suggestions to add to the notes section of your vehicle maintenance checklist:

REPLACE WINDSHIELD WIPERS

Windshield wipers need to be replaced about once every year, or whenever the effectiveness is compromised. In winter months, it could also be a good idea to install winter wiper blades for optimum performance. You should also pull your wipers away from the window when parked during the winter to prevent ice buildup.

BATTERY PERFORMANCE CHECK

Your car battery is one of the most important components for your vehicle to run. A car battery supplies large amounts of electrical current for the starter, engine and other electronic accessories in the vehicle. Extreme temperatures affect the performance of the battery so regular battery testing will ensure that battery will perform when you need it to.

CHANGE TIRES

Depending on where you live and the winter driving conditions you might encounter, you might want to switch your tires in cold, snowy months to a winter/snow tire. When the temperature hovers at or below freezing consistently, the tire compounds in non-winter tires hardens, decreasing traction and handling performance while increasing braking distance. Winter tires are have tread patterns and compounds designed to remain soft in the cold and provide grip in snow, slush, and icy driving conditions.

CHECK COOLANT LEVELS

It’s also important to check your antifreeze levels in your radiator in winter months to keep your radiator or engine components from freezing. A 50/50 mix of antifreeze to water is generally recommended, but check your owner’s manual or with a professional to be certain.

Sticking to a car maintenance schedule, and keeping good records of what you’ve done, can help extend the life of your vehicle and protect you against breakdowns, expensive repairs, and other unwelcomed surprises.
