Reasons Why The Engine of Our Vehicle May Not Start

There are many reasons why the engine of our vehicle may not start. In the following article, we will talk about the most common at present symptoms of why your car does not start. The causes usually happen from one moment to another. This may influence the way that a vehicle starts even if moments ago, your engine was running fine.

Here are the main reasons why the engine does not start:

Discharged or bad battery

This option is the most standard and the most common. Sometimes people leave a device such as the radio on or the door open, which causes the car light to remain on. This will consume lots of currents, especially if a battery is not in good condition. More than often, this generates the problem of not being able to start the engine. In some cases, the engine cranks very slowly or not when putting the key in the ignition position because there is no longer sufficient battery current.

Loose or dirty battery connectors

Another frequent reason that has to do with the battery is the faulty battery connectors, either because they are deteriorated, dirty, or loose. Any of the three options suggests a bad contact that will cause the current to be not the best even when the battery is well charged.

Bad fuel pump

Gas pumps usually placed or submerged inside the fuel tank are one of the damages that often occur in cars. These pumps are an electric motor and therefore have brushes or coals subject to wear, so it is reasonable to stop working. Of course, they can stop working from one moment to another, ie, "I just turned off the engine of the car, just enter the super and buy the newspaper, I went out and no longer started me."

Security System

Currently, older vehicles have security systems where we find keys that are recognized by the system. Some keys could be shared and ordinary, so the owner to possess only one goes to the locksmith to make a copy to keep it in the wallet, often when the original is lost. They make use of the copy and surprise, the engine turns but does not start because the key is not recognized.

Engine Starter

Very similar to the gasoline pump, the starter is an electric motor which is also composed of brushes or coals. When these components are almost entirely worn out, the starter will stop working. The engine might not start because of this. In automatic cars, the problem is much more significant because if the starter fails, we can not even choose to start it "pushed." In today's cars, there is a possibility that even when the transmission is manual, you can not start the engine using this type of procedure because you need the start signal for many engine modules.

Faulty ignition system

For an otto four-stroke engine to start, we need in the compression cylinder, fuel, and spark. Typically, many times the coil in charge of generating the high voltage so that it looks like the spark in the electrodes of the spark plug fails to have problems generating the high voltage. Sometimes there are cracks in its body that facilitate the jump of current in another place. Without a jump of current in the spark plug, there is no possibility to start the engine.

Spark plugs in bad diesel engines

Unlike petrol or gas engines, diesel engines do not ignite the air-fuel mixture utilizing a jump in the spark plug. Rather by self-ignition through compression, the high compression ratios in diesel engines cause an increase in the air temperature. This causes the diesel to self-inflame when it comes into contact with the air in the compression phase, as we can see the air temperature must rise, the glow plugs cause an increase in the air temperature for cold starts in diesel engines.
