Common reasons why a car engine won't start

The reasons can be both general and specific. Let's look at the most common problems.

The first place, perhaps, can be safely given to problems with the battery. Very often, the engine does not start as a result of battery discharge. However, it is not necessary that the charge is completely absent. In many cars, the starter will refuse to crank if the battery puts out less than 10 volts. Given this information, it becomes clear that you should not forget to recharge the battery on time.
However, not always a complete failure or problems with starting the engine are associated with a low battery level. Quite often, oxidized or loose terminals are to blame. From time to time, you need to clean them with sandpaper to remove a coating of oxide film, which does not conduct electricity well. The same applies to the contacts on the battery itself.
After stripping, it is recommended to lubricate the terminals with machine oil or lithol so that they do not oxidize. It would be even better to change the copper terminals and install brass ones.

In second place in terms of frequency, you can put a very simple and harmless reason - lack of fuel. There are two options: it may not be in the tank, or it does not enter the engine.
The actions of the driver in this case are extremely simple. First, check the tank (the sensor may fail or show incorrect values). Second, check the fuel line. Perhaps there was a leak somewhere and it filled with air. The complexity and cost of repair depends on the nature of the breakdown. Sometimes it is enough just to replace the hose under the hood.

Fuel may not enter the combustion chamber due to a clogged carburetor or nozzles on injection engines. In addition, it happens that the fuel pump fails. The reasons for this may be different, but the most common of them is overheating of the fuel pump. Of course, we are talking about those cars in which the pump is installed under the hood (usually carburetor). It overheats especially often in the summer heat.
Another option, although very rare, is that gasoline has lost its properties (evaporated, diluted with condensate, etc.). This happens if the car has stood for more than a year. In this case, it is enough to add fresh fuel or drain the residues, and then refuel with suitable fuel.

Problems in the ignition system

No spark at spark plugs or wet candles. This is also a very common reason why the engine will not start. You can check the candles yourself. To do this, you must have in the trunk candle key. Checking for a spark is also not difficult.
To do this, you need to unscrew the candle, put a contact wire on it and try to turn the ignition key at the moment when the candle itself is near the metal. A good spark should be "fat" and bright. If the spark is weak or not at all, it is worth taking a closer look at the contacts of the candle. Perhaps they were covered in soot. In this case, they must be cleaned with sandpaper or a wire brush. If this does not help, then it is worth trying to replace the candle.

It happens that the candle is in order, but there is still no spark. Here you need to check the armored wires and even the ignition coil. By the way, the capacitor on the ignition coil may fail. It is advisable to have a spare with you (it costs a penny).

No spark on center wire. You can check it like this: the central wire is disconnected from the cover of the distributor, the tip is unscrewed. After that, you need to turn the key and keep the end of the wire near the metal. Should be a good spark.
Ignition switch problem. It happens that in the castle itself some kind of terminal falls off. Especially on older cars. Naturally, you need to know where to put it again. In addition, fuses may blow. Therefore, it is always worth having a set of spares in the car. It is inexpensive, does not take up space, and a blown fuse can be not only the reason that, for example, turns do not work. Worse, when for this reason the internal combustion engine does not start.

Other possible faults

Problems with the retractor (traction) starter relay. The most common problem here is burnt nickels (you can only see when the device is disassembled).
In addition, contacts can be soldered from them. In this case, when the ignition key is turned, only a quiet click of the starter relay will be heard, and the retractor will be silent. If it is working, it will make a clear metallic click. On the road, it is unlikely to be able to fix it. Although the repair is inexpensive and relatively uncomplicated.

The starter has failed. If, when the car engine starts, when the key is turned, a click is clearly heard, but the start does not occur, and the battery wires heat up or even smoke comes from them, then the starter needs to be changed.
Ignition set incorrectly. This happens after an engine overhaul. In this case, you should contact a specialist.

The distributor is flooded with water or just wet. This happens, for example, when driving on large, deep puddles. In this case, the spark will simply go away (pierce) and not get to the candles. The solution is simple: wipe the distributor and let it dry.
The engine may not start because it is jammed. Signs and causes of a wedge is a vast topic that will be difficult to cover within the framework of this article. In addition, for various reasons, they can completely lie down piston rings etc.

Results

So, as follows from all that is written above, answering the question of why the engine does not start is not so simple. All reasons can be divided into three main groups:
-problems with fuel supply;
-problems with the electrician;
-problems with mechanics (that is, with the engine itself).

It is recommended not to forget to regularly carry out scheduled maintenance, additionally check the engine and attachments before a long trip, charge the battery in a timely manner and fill the gas tank with only high-quality fuel.

If all components and elements of the cooling system work properly, the normal thermal regime of the engine (coolant temperature 80–100 ° C, the arrow of the coolant temperature indicator is in the white zone of the scale) after warming up is automatically maintained by the thermostat.

Periodically, as well as in case of a violation of the normal thermal regime of the engine (overheating under normal operating conditions or prolonged warming up of the engine after starting), it is necessary to check the operation of the thermostat and the electric fan of the cooling system. Check the operation of thermostat 3 (see fig. Bottom view of the cooling system radiator) can be touched directly on the car. After starting a cold engine with a working thermostat, the outlet (lower) hose 5 of the radiator begins to heat up when the coolant temperature rises to 80–85 ° C. Earlier or later heating of the outlet hose of the radiator indicates a malfunction of the thermostat associated with the valve freezing in open position or stuck in the closed position. If the problem cannot be corrected, the thermostat must be replaced.

If the electric fan 1 does not turn on when the arrow of the coolant temperature gauge reaches the last mark before the red zone of the scale (107 ° C), then this indicates a malfunction of its switch-on sensor 2, the relay or the electric fan itself.

For all checks, you must first make sure that the coolant temperature gauge is working.

Good afternoon. If you have a dashboard without a temperature indication, then a blue lamp should light up at startup, which goes out when it reaches 60 degrees. In principle, it is not necessary to wait for it to go out, it is enough to warm it up for 5-7 minutes. If the equipment is with a scale, as in the photo, then the lower limit corresponds to the blue lamp (about 60 degrees), the average is about 90 degrees, the red zone with the letter H is about 120-130 degrees.
Also, the exact temperature of the internal combustion engine can be found by connecting diagnostic equipment, which takes readings directly from the sensor, or put an on-board computer.

Good afternoon dear owner! As colleagues wrote, it all depends on the configuration of the car, if there is no arrow temperature indication on the dashboard, then you should be guided by the icons. When the blue goes out, the engine is warmed up, if the red icon lights up, it indicates overheating. In principle, if you monitor the level of antifreeze and the cleanliness of the radiators, there should be no problems. Periodically, every three to four years, depending on the operation, it is worth washing the radiators, below is a photo of what happens to it during operation.

• Today, some manufacturers believe that the parameters of the motor, which the driver cannot influence during operation, or which, according to the manufacturer, he should not influence, do not need to be shown to the driver. In your case, the driver is required to stop operation when overheating and reduce the intensity of driving when cold, and otherwise drive without restrictions. What temperature does not play a role, 85 ° or 98 °, you will not notice the difference.

  Moscow, Chrysler Voyager

  Hello dear car owner!
  On the Kia Rio, depending on the configuration, two versions of the instrument panel are installed. If you have a car in the basic or second configuration, then you can find out the temperature only approximately by the lights on the instrument panel. If you are not satisfied with such temperature readings, then you can install an additional on-board computer.

  I have a car for 4 years for 4 years, the blue light on the dashboard did not light up, because it simply does not exist

  Tyumen region, Kia Rio

  I have a KIA RIO 11 years old, the light bulb you indicated does not suit me because the panel is not mine. I have a red light on the panel, but it only lights up when the engine overheats. The funny thing is that in the car service they don’t know anything about this light bulb

  Tyumen region, Kia Rio

Kia cars Third generation Rio equipped with G4FA engine from new series Gamma (since 2010 these power units replaced the motors of the Alpha series), volume 1394 cm cube, which complies with Euro-4 environmental standards. It is produced at the Chinese plant "Beijing Hyundai Motor Co".

In addition to Kia Rio-3, this engine is also installed on Kia Ceed, Hyundai "Solaris" (or "Accent"), Hyundai i20, Hyundai i30.

Specifications of the G4FA engine

• The G4FA engine has 4 cylinders, each with 4 valves.
• Maximum power is reached at 6300 rpm and is 107-109 horsepower.
• The engine uses a timing chain with tensioners (for a guaranteed motor resource of 180 thousand km, the chain does not require maintenance).
• The manufacturer recommends using fuel - AI-92, and motor oil with viscosity parameters - 5W-30 (see "").
• The engine maintenance interval is 15 thousand km (see "").

7 major flaws and malfunctions of the G4FA engine

1. The occurrence of knocking in the engine(most common problem).
   If it goes away after the engine warms up, then, in 90% of cases, the timing chain is the cause (do not worry, this is the norm).
   If it does not disappear with operating temperature engine, then most likely the cause is unadjusted valves.
2. Chirring, clatter, clicks, etc. sounds heard when the engine is running.
   You should not be afraid of these sounds - this is how fuel injectors work.
3. The occurrence of uneven engine operation("floating" turns).
   Solved by cleaning the throttle body. When this does not help, then you should try the latest "firmware".
4. Vibrations that appear on idling.
   May occur with a dirty throttle or spark plugs (see "How to replace spark plugs"). kia ignition Rio 3"). If after flushing the throttle body or replacing the spark plugs, the vibrations do not disappear, pay attention to the engine mounts.
5. Vibrations during rotation of the crankshaft at a frequency of about 3000 rpm.
   According to official dealers, the cause of vibrations is the occurrence of resonance between the units and components of the car due to design features. In order for the engine to come out of resonance, it is recommended to sharply depress the accelerator pedal and release it.
6. Whistle under the hood.
   The reason is the weak tension of the alternator belt. After replacing the tensioner pulley, the whistle disappears.
7. The appearance of oil smudges from under the valve cover.
   All is treated with a simple gasket replacement.

It should also be noted that due to the absence of hydraulic compensators in the engine, every 95 thousand km, it is necessary to replace the pushers and adjust the valve clearances. Despite the high cost of the procedure, this should be done without fail, because. in the future, this can lead to significant problems in the operation of the engine: “triple”, noise, burnout, etc.

The most depressing thing is that the listed malfunctions can appear at the very beginning of the car’s operation. That's why buying a used Kia Rio-3 with such an engine should be very careful, and if you take a car with a mileage of more than 100 thousand km, you can buy "firewood".

Attention! The cylinder head of the G4FA engine cannot be repaired, because. boring under repair size not provided by the manufacturer.

How? Have you read yet? Well, it's useless...

We will be grateful for the pressed social buttons!

KIA Rio sensors, like any other modern car, allow the ECU ( electronic unit controls) to properly prepare the fuel-air suspension, control the operation and condition of the engine as a whole. Therefore, any deviation in the operation of the sensor affects the stability of work, vehicle dynamics, and fuel consumption. And sometimes, for example, when the position sensor fails crankshaft, and to the complete inoperability of the engine. Therefore, if on dashboard car, the "Check" lamp with the image of the engine lights up, urgently contact official dealer(if the car is under warranty) or to any service station for diagnostics and finding out the error code.

Among the many owners this vehicle there is a myth that Rio does not have a temperature sensor and this is due to the fact that the owners of configurations without supervision panels, do not see the temperature of the engine. In fact, it naturally exists and is correctly called - Engine coolant temperature sensor (ECTS). He is located in engine compartment, it depends on his work how rich he will be fuel mixture. It also signals whether the engine is cold or vice versa overheated.

Errors related to the sensor Kia temperature Rio:

• P0116 Incorrect engine coolant temperature reading
• P0117 Engine Coolant Temperature Sensor Low
• P0118 Engine Coolant Temperature Sensor High
• P0119 Engine Coolant Temperature Sensor Malfunction

The resistance of the sensor varies depending on the temperature of the coolant. In order to check this sensor, remove it, lower it into a container with water of a certain temperature and measure the resistance of the sensor, it must be within the limits indicated in the table on the left.

If it is not, replace the sensor.

Crankshaft sensor KIA Rio 2012-2013

The crankshaft position sensor (CKPS) is one of the main sensors on the correct operation of which the performance of the Kia Rio engine depends. If the electrical circuit of this sensor is broken or the sensor itself fails, the car simply will not start, since even fuel will not be supplied.

The sensor is located in the block and gearbox housing. Unlike the temperature sensor, the Kia Rio crankshaft sensor creates an alternating current, which indicates the position of the crankshaft to the ECU. it is possible to check the performance of this sensor only with the help of specialized devices, therefore, if you suspect that it is malfunctioning, it is easiest to replace it.

Crankshaft sensor errors:

• P0385 Malfunction in the crankshaft position sensor B circuit
• P0386 Crankshaft Position Sensor B Invalid
• P1336 Crankshaft Position (CKP) Sensor Not Read
• P1374 Crankshaft position (CKP) sensor frequency change
• P0387 Crankshaft Position Sensor B Low
• P0388 Crankshaft Position Sensor B High
• P0389 Crankshaft Position Sensor B Malfunction
• P0335 Malfunction in the crankshaft position sensor A circuit
• P0336 Incorrect indicator crankshaft position sensor A
• P0337 Crankshaft Position Sensor A Low
• P0338 Crankshaft Position Sensor A High
• P0339 Malfunction of the crankshaft position sensor A

Keep in mind that most errors will be due to an open circuit in the sensor or its malfunction.

Camshaft sensor Gamma 1.4 / 1.6 Kia Rio

In fact, this is a Hall sensor, its task is to determine the position of the camshaft, it directly works with the CKPS (crankshaft sensor) This sensor is installed on the motor cover, interacts with the camshaft gear.

Diagnostics of malfunctions of the Kia Rio camshaft sensor is carried out only using a special scanner, the purchase of which is not advisable, therefore, we will exclude other causes of failure, it is better to replace this sensor, since The camshaft sensor cannot be repaired.

• P0340 Malfunction in the camshaft position sensor circuit
• P0341 Wrong indicator / camshaft position sensor not adjusted
• P0342 Low camshaft position sensor
• P0343 High camshaft position sensor

Speed ​​sensor

The Kia Rio speed sensor is located strictly vertically on the manual transmission housing. Its malfunction does not lead to serious changes in the operation of the engine. However, the vehicle speed will not be displayed on the instrument panel. The speed sensor is not repaired, but only changed. Its most common malfunction is the destruction of the drive gear. This is not scary and does not harm the gearbox itself, the sensor itself just needs to be replaced.

Speed ​​sensor error codes:

• P0500 Malfunction in the speed sensor circuit
• P0501 Speed ​​sensor out of adjustment
• P0502 Low speed sensor
• P0503 High or unstable speed sensor

Air flow sensor for Kia Rio

A slightly incorrect concept, since there is no air flow sensor in Rio in its direct sense, but there is an absolute pressure sensor (MAPS) and an incoming air temperature sensor (IATS).

Together they perform the role of "mass" or DFID on domestic cars.

If your car has become unstable at idle, all diagnostic and repair procedures must begin with cleaning the throttle.

Throttle control module and idle speed sensor

This module combines several devices, namely:

1. damper motor
2. Sensor idle move
3. Throttle body assembly

Directly to this system, you can add and electronic pedal gas. As a rule, on cars with low mileage, neither the idle speed sensor nor the assembly as a whole cause problems. However, if symptoms of an unstable idle, jerky acceleration or other troubles appear, the throttle assembly needs to be cleaned.

Fuel level sensor

We will not write much about the fuel level sensor, it is located directly in the tank. It rarely fails.
