Why the car does not start

It is highly inconvenient whenever the engine of the vehicle suddenly dies, or it simply turns off while one is driving.

The fact that the car won’t start shouldn’t be cause for concern in and of itself. It is likely just a minor flaw in the product.

Why the car does not start

On the other hand, determining the true cause necessitates a thorough comprehension of how a vehicle functions.

In this article, we will explain everything that can cause a vehicle breakdown and what is helpful when the car won’t start in such cases.

What does a vehicle require to function correctly?

Fuel: gasoline, diesel, or gasoline
To regulate the movement of moving pieces, use the steering mechanism. Energy: electrical current to activate the starter motor
Air: to prepare the mixture

It is possible to fix the engine immediately, or it may require a very complex repair, depending on the malfunctioning system.

Engine won’t start anymore – Fuel system failure.

The fuel supply is typically the first suspect if the car won’t start or shuts down.

It is possible to fix the engine right away. Even if you try starting the machine with the choke, the vehicle may be out of fuel if the engine will not start.

The fuel level sensor may be jammed inside the tank if the fuel gauge continues to indicate a certain amount of fuel left.

This can be verified by adding some fuel to the tank and attempting to start the vehicle once more. This requires patience because the fuel system needs time to vent itself after being completely empty.

When the tank empties quickly, you should sniff the gas to see whether there is any gasoline odor. There may be a problem with the fuel hose.

Last but not least, there is also the possibility that the fuel pump has stopped working.

Vehicle failures are usually caused by transmission system issues.

Usually, a transmission system failure in a car results in serious consequences. The engine will immediately stop and no longer start if the timing belt or chain breaks.

When this happens, the interior of the engine is frequently seriously damaged, and the cost of repair is extraordinarily high.

One way to confirm this is to look at the housing for the timing belt or chain. When the drive elements become dislodged, the root cause has been located.

It is not necessary to replace either the belt or the chain for the repair to be complete. It is required to take apart the engine in its entirety.

Car compression does not start – Power supply failure

When the car does not start, the most common cause is usually a failure in the power supply. The electrical generator is responsible for the production of current, which is then stored in the battery before being distributed to the spark plugs in the engine compartment by the ignition coil and distributor.

In circuits, there will always be a flow of electric current. If the electrical circuit is broken, there will be no further transmission of electricity; instead, it will go back to the electrical generator through the body.

Because of this, the electric generator and the battery always need to be grounded, which means they need to be connected to the body.

Corrosion If this is not detected, the car’s starting will become increasingly difficult until, at some point, it will no longer function.

The solution to the problem is straightforward to implement. After unscrewing the ground wires, clean them thoroughly with polish and terminal grease before reattaching them.

After that, they are screwed back on, and the issue should no longer exist.

The ignition coil is responsible for transforming the 24-volt electricity supplied by the electric generator into a powerful 10,000-volt ignition current. From the ring, a wire travels to the distributor.

On older vehicles, this wire can become disconnected. This will be the most specific cause if the car does not start.

It is sufficient to realign the cable so that it is in the appropriate location, and that is it. If, on the other hand, the line is installed correctly but sparks still fly when the engine is started, this indicates that the insulation layer is broken, and a rodent bite may have caused the problem.

Insulating tape should be wrapped around the ignition cable as a stopgap measure.

The engine compartment should be inspected for other rodent bites if the car can start after this.

The engine compartment should be checked if the car continues to start. A complete engine failure is possible if the coolant hose has also been damaged.

A problem with the starter motor related to the electrical supply could also occur. This comprises an electric motor and a device for releasing an electromagnetic clutch.

The starter motor is susceptible to wear and tear over time, and the contacts are at risk of rusting. A clattering sound is the telltale sign of a starter not functioning correctly.

In this scenario, the electromagnet will no longer completely disengage the gearbox from the starter, but the electric motor will continue to rotate it.

This flaw might be correctable with a little bit of luck. However, in most cases, the only component that can be repaired is the faulty one.

If the electric generator fails, the vehicle’s battery will no longer be charged, usually indicated by an indicator light on the dashboard that glows continuously.

If it is ignored excessively, the ignition coil will eventually cease to receive electricity. In this scenario, it is first necessary to charge the battery, and only after that should the electrical generator be inspected.

The generator typically suffers from minor flaws, the majority of which involve either the drive belt becoming damaged or the carbon brushes becoming worn out.

Both of these problems can be remedied with a modest investment of time and money.

Why the car does not start

Air supply failure

Although it is possible in theory, it is highly uncommon for an engine to fail due to air supply problems.

Suppose something foreign becomes lodged in the intake system, or the air filter becomes wholly clogged with debris. In that case, the engine will no longer receive enough oxygen to combine the other ingredients properly.

An increase in fuel consumption and a hot engine are the typical warning signs of this failure.

If this is the case, all that must be done to restore the car’s functionality is to replace the air filter and inspect the intake system.

Failure of the oil and water supply

If the supply of cooling water or lubricating water fails, the engine could sustain significant damage.

Failure of the well-known piston seizure that occurs due to the absence of one of these substances is a consequence.

If this issue manifests itself, the vehicle can no longer be maintained using everyday household items; instead, the engine will need to undergo a comprehensive overhaul.

For this reason, the following is applicable: as soon as the engine indicator light or the warning lights for cooling water or oil pressure come on, turn off the engine immediately!

How to proceed when the engine will not start

With this list, you can quickly narrow down the cause of a car that has stalled:

Was the vehicle unable to start during the trip?

Was the car unable

– Faulty ignition contacts.
– Engine failure.

Does the car then not start anymore?

– Ran out of fuel.

Starter motor turns: engine regulation OK, empty fuel tank or loose ignition cable

– Check the fuel gauge
– When the fuel gauge is empty: check the ignition wiring

– When fuel gauge discount

Starter motor not working: engine failure, engine block

Start the machine using an external power supply (in such a case, the battery will typically need to be replaced).
– If the choke works when using an external power supply, but the car will not start, check the fuel supply, air, and ignition wiring.
– If the starter motor does not turn, the problem is either with the choke or with the engine itself. Tow the vehicle (Caution: diesel vehicles cannot be towed when cold!
– If the car will not start despite being towed and the wheels are locked, this indicates that the engine has broken down and will require extensive repair.

If none of these solutions work, there is only one other option before driving to the repair shop: check There might be a problem with the fuse that controls the glow plugs.

If everything seems to be in order here as well, then the vehicle needs to be taken to the repair shop.
