Often drivers face that they are VAZ 2109 ceases to start For any reasons. If the car does not start, then the question immediately arises, "where to start?". In fact, everything can be quite simple, and in 90% of cases - this is a typical problem that is diagnosed and solved quite easily.
Why VAZ 2109 does not start - the search for the cause
First of all, you need to check the fuel, spark and air.
I would advise to start checking the air intake (phase compression and gas distribution), you can also start with.
Tags on the pulleys may coincide, but the compression can take a little for example: on one cylinder 10 atm, on the second 9.5 atm, on the third 7 atm, and on the fourth 8 atm, it can fix it only. Of course, it is more serious to do the engine repair, but while it needs to be postponed, as we need to start the car. Having such compression, the engine will work and even well, but at idle will be subdura.
Power system check
Next, begin to dig in the system. It will be necessary to make sure that in the required level, the pump helps the fuel correctly, the idling valve works without failures. Consequently, with the fuel supply is all in order. Also, do not forget to check the candles, after a pair of attempts to start the engine, they will certainly fill.
Checking the ignition system
Once the previous breakdowns were not confirmed, then the problem must be sought in the ignition system. For the usual check, simple tackers will use, they can be bought without any problems in any automata. But to begin with, it should be understood in the device and the operation of the ignition.
And so, in our case, the vaz 2109 costs the contactless ignition system. This system includes:
- coil
- distributor,
- switch,
- hall Sensor.
One terminal coil is connected to the battery, and the second to the output transistor of the switch. The switch opens the output transistor when the signal drops in zero. At this point in the secondary winding of the coil, the high voltage current appears, approximately 25 kV, and in the primary current more than 300V. As a result, high-voltage voltage arises on the candlelight, as a result of which a spark appears on the candlelight.
But for the emergence of the discharge, it is necessary that the coil is charged. Before the control pulse from the Hall sensor, the switch predicts when you need to close to the ground to charge it.
Moreover, he does it so that the charge time of the coil remains approximately unchanged. Otherwise, the rehabil to the coil will happen. For this, the switch is calculated by the desired pulse period, which come from the Hall sensor. In other words, it all depends on the speed of the engine, above the turnover, before the switch begins to close the coil, but the time of the closed state will not change.
Now you can proceed to testing. First of all, you need to check the spark on the candlelight - you can use a special arrester for this. No result.
So the Hall sensor or switch may be to blame, may have a mass or power to switch. In order not to guess for a long time, we use AZ-1.
AZ-1 is an emergency ignition, they can be used in the rain, when driving on the puddles. If we speak in other words, you can call it a substitute for the Hall sensor.
The MD-1 sensor is instant diagnostics, it is useful for, the Hall sensor and the ignition lock.
First of all, we took advantage of MD-1. This sensor is connected instead of the switch, as soon as it is picked up, you need to turn on the ignition, do not start:
- if the "P" LED caught fire - this means that the ignition relay and the ignition lock work properly.
- burning LED "K" - the primary winding of the ignition coil has no damage.
- turn on the starter: if the LED "d" flashed, then the Hall sensor in working condition.
In the event that it does not blink, you will have to use the AZ-1 instrument, connect it instead of the Hall sensor.
Such instruments for instant diagnostics of contactless ignition systems are sold on the Internet literally for 100 rubles. But if you do not have the opportunity to purchase such, then you will have to spend much more time and check each sensor by a multimeter separately.
Everything works, but the engine starts, does not want. After a careful inspection of the ignition coil, carbon walkways were found at the site of connecting high-voltage wire. Changed the coil and wire. The engine immediately earned, as before.
I hope such a vital will help to find the reason why your car does not start too.
How often there is such a situation that your hot beloved car (VAZ 2109, 099, 08) flatly refuses to start or stalled along the road? You should not immediately call gifted masters or drag a poor thing in service on the rope. Joyful news is still alone. I will say what to do, but only if your hands grow out of the right place :).
The stigled and non-shy engine can be several reasons. Initially, turn the key in the ignition lock and listen to the starter, if there is no reason in it, but this is said and "is clear". If the starter twists, go further. How it would not sound stupid, but it is necessary to check whether gasoline in the tank.
Turn the key and look at the fuel residue control lamp in the tank. If we are confident that gasoline is going on and check the presence of spark. I will withdraw any candle, we stick it into high-voltage wire and touch the engine (for mass) ...
Here we need an assistant. We plant it behind the wheel and let the key turn the key. Is there a spark on the tip of the candle? Hood. Not? badly. Faulty switching unit or its wiring. This is difficult to do something. Try changing the switch. We also follow the spark on the central wire coming from the coil. Check the same method with candles. The absence of sparks may indicate the coil malfunction.
Check the power system. If in the street Winter, the supply of gasoline could get and frozen water. We check: unscrew the "air", and press the fuel pump button several times. Bulkaet? Well gasoline enters the carburetor. not?
Or frozen the above-mentioned water in some way that fell into the system, or, which is more likely to be faulty than gas station. Pay attention to the fine cleaning filter. It should be inspected for cracks and damage. You can also watch hoses for which gasoline comes. All checked? Power system in order?
Next step, candles! Unscrew the candles. Everything. We look, whether there is a Nagar. The processed driver should always have a spare set, workers, proven candles. "Oveanted" (black candles with naigar and flooded with gasoline), it is useless to clean the skin and wipe. They must be hired over the gas stove.
So working candles inserted, did not help? Let us turn to the ignition system. Remove high-voltage wires from a traver. By the way, from behind the wires, the car may not start, check them. We look at the lid of the traver.
If there are chipsets inside, contact, change the lid. Further removing the slider. It can also be replaced. Unscrew 2 bolts. Disconnect the wiring from the Hall sensor and change the sensor itself. We collect everything in reverse order with new spare parts.
The location of high-voltage wires on the lid of the traver is not in order. The first wire (on the lid it is marked with a number 1) comes from 1 cylinder (extreme left), then 2 cylinder will go clockwise, 4 cylinder and 3 cylinder. If the machine is confused, the car will be terribly torn or not at all.
It remains to check the timing belt. It is on the left side, under the casing. Remove and look at the belt teeth. If not enough and the belt slipped, then it must be changed. Only here is a question in consequences. If you have a 1.3 engine, then the valve may be wondered (don't even drive yourself). If 1.5, it is possible nothing terrible.
Well, in principle and the whole system. Everything should start. If not, you can with a clean soul (I did what I could) drag it with third-party crafts. If the machine does not work at idle, check the solenoid valve. It is screwed into the carburetor on the right side. Remove the terminal.
Turn the key by turning on the ignition and tap the valve terminal several times. Are there clicks and spark? Well, it works. Just unscrew it and blow the jibeler on the end. Back the valve needs to be tightened with hands, preferably without dragging it.
Also, unstable work at idle or movement of jerks can be a consequence of a non-adjusted carburetor, actually as invertible (from the oppressed mixture) of the candle.
Good luck on the roads.
Favorite Old Lovels often presents problems, refusing to start, his motor stalls at the most inopportune moment? Familiar situation. Consider first the problem from the theoretical side. For the operation of any internal combustion engine, it is necessary to have 3 factors - air, fuel and sparks, flammifying the air-fuel mixture sucking inside the cylinders.
Several practical councils managed to experience motorists:
- To begin with, turning on the ignition, determine whether the starter is spinning. If not, then the "hedgehog is clear" what's the matter. The charged battery when the ignition is turned on, makes a characteristic click of the retractor relay.
- After, if the starter passed the test, check the sensors of the presence of fuel, and it is better to look into the tank itself.
- Further one can no longer cope. We find an assistant to scroll starter using the ignition key and byverting any candle in compliance with the necessary precautions, poke it into high-voltage wire and closer to the "mass" holding it in a centimeter from the target. There is a spark - excellent. Not starting 2109 Carburetor Starter twists spark. Checking the same method, the presence of sparks on the central wire and, if there is, everything is fine.
- The absence of sparks in the first case means uniquely replacing the switch, and in the second - the coil malfunction ("Babina" fails very rarely, but it happens).
Lack of air and block filters
There are no 2109 spark carburetor there is gasoline. In winter, the presence of gasoline does not mean his arrival in the carburetor, as the water could freeze. Get to the fuel pump and press the button. It does not bouularity - this means that the water has frozen, otherwise, accordingly, that does not frozen and fuel comes. There may also be a fuel pump, a fine cleaning filter, or give a fracture hoses. After removing the air filter cover, we inspect the inner space for its purity and try to start.
Engine without lid. If he started, then there is no air access to the carburetor (scored and / or with an oil filter). If there is no effect, then continue the check. If the fuel pump has not failed, it is possible that the air does not pass into the float chamber or the slide needle valve. After an unsuccessful blowing with compressed air, it is necessary to blow with a removed carburetor with a lid and if there is no effect again, the replacement is the needle valve. You can still check and blow up, having twisted it, the jigger (wrapping it back it is necessary very careful not to "drag"). There is still a way to reanimate the motor. After removing the hose spray a bit of gasoline in the 1st chamber, which is closer to the car's salon.
Spark plugs are faulty
If everything is in order, then we turn to the next step of the check, namely to the candles. You unscrew them all and we look at the presence of a car and / or fuel residues. If any, then it is necessary to hide them with the help of pliers over the gas stove or, in its absence, in another flame of any burner. Insert spare "workers" candles.
Fault Wiring Wires
Check the wires, as they can also cause malfunctions. If from the inside the cover of the chip timbble and the contacts are, then it needs to be changed. After removing the slider, after checking that the drum does not touch the Hall sensor, unscrew the bolts and disconnecting the wiring replace the sensor.
The wires on the cover of the traver go in the following order (the wrong order of the connection of the wires can also be the reason that the car does not start):
- The first (it is also noted on the lid) comes from the extreme left and also the first cylinder.
- Next, if you look clockwise the second cylinder follows, and behind it is the 4th.
- The extreme right wire comes from the third cylinder.
Under the casing there is a rubber belt of the gas distribution mechanism. If the teeth (one of them) was finished, and even more so if there is a blast on the belt, then you need a replacement.
If you have any questions, why your nine does not start, I recommend to watch this video:
Alternative ways to launch a car
If, after one of the above operations, the car started, then rejoice that they coped with the breakdown yourself. If nothing helped, then you need to carry a car for repair. But before the car service, you still have to get in this case, "nine", like all carburetor cars are unique. A modern foreign car without a battery is nowhere, but "Zhiguli", if you start with the "Tolkucha" or push under the slope can go as much as you like (the main thing is not to join the motor).
The process is as follows:
- Ignition turns on.
- Pushing the car so that it gives the speed at least 5 km / h.
- The clutch is squeezed and the third transmission turns on (of course any transmission will go, but the 3rd best for the "cold" start).
- The clutch is released and when, by the inertia, the vase will be checked his knees, the car will certainly become. After the clutch is squeezed and the third transmission turns off.
The owners of "nine" often face the situation when the VAZ 2109 does not start. Is it possible to determine the cause of the breakdown and do without a hundred? If we seize certain skills and knowledge of the engine starting system, then yes.
Lada may not be launched differently. First case: badly start on the cold. This implies fuzzy launch of the motor after a long parking lot. It happens when VAZ stalls on the go, that is, it is bad for hot. In addition, the "nine" was produced both with carburetor engines and injectors. Differences in the search for breakdowns in these two aggregates are essential. We find out how to look for the cause of failure for both variants of the power unit.
Differences of the carburetor and the injector breakdown
There are common cases of engine start failure for the injector and carburetor. But now consider the distinctive features with such a malfunction as the "died motor". Differences in the search for breakdowns are due to the different principle of action of two systems.
VAZ 2109 carburetor - the motor is activated in a combustible mixture into it. This is due to the fact that in the intake manifold and the atmosphere is formed a pressure difference. In this case, for the normal start of the car, the three components are sufficient:
- gasoline;
- air;
- sparks.
The starter leads to rotation of the crankshaft, while the resulting mixture (fuel with air) is sucked into the cavity of the cylinder. Next, the valves of the internal combustion engine are closed, compression tact occurs, at the end of which the spark appears on the candle and the fuel mixture is ignited. Motor starts.
And in the case of a fuel injection injector and the quality of the resulting mixture is controlled and adjustable. The combustible mixture with nozzles is injected into the cylinders (directly into the combustion chamber). Therefore, the conditions for suction of air and gasoline do not need to be created here.
The breakdown in the injection engine can be briefly described as follows: either the spark is not formed, or access to cylinders is closed for combustible mixture.
In addition, the VAZ 2109 injector has many sensors, electronic control unit and electric fuel pump. They can also fail. Consider the procedure when searching for breakage separately for the carburetor and the injector.
Do not start the carburetor engine VAZ
If this happens, you need to check:
- the presence of all technical fluids;
- battery charge;
- starter condition;
- fuel pump and fuel filter;
- candles, the presence of a spark;
- tags of the belt of the gas distribution mechanism (TRM);
- the state of the carburetor.
If the starter does not rotate the crankshaft, you need to make sure that the battery is charged. When turning the key, a click is required. For this, all connectors for the starter must be put. If the crankshaft rotates, looking for further. We define what is not in the cylinder: sparks or mixtures. To check the spark, remove the high-voltage wire from the candle, bring to the mass and run the car from the key.
If the spark is not supplied to the VAZ 2109 candle, we are convinced whether the "flash" is obtained (ignition distributor). To do this, turn off the wire from it, bring to the metal case and start the starter. The presence of a spark indicates that the problem is in the battle. Checking its slider and run the contact of the wires.
Provided that the rubber does not "spark", diagnose the ignition system. This can be done with appliances. The principle of operation of all devices is identical to: Display power and operation of the switch and the hall sensor (sensor for determining the moment of spark) by sunburn the light indicator.
The device is connected to the rupture of the switch circuit, remove the switch from the switch and are connected to the instrument connector. Another connector of the device is put on the switch. When the starter is rotated, the switch light bulb and the hall sensor light should blink. If the switch lamp does not burn, it needs to be changed. When the sensor lamp does not burn, make sure that the track slider rotates when the starter is running. If the starter rotates, but the slider is not - a torn timber belt. If the slider rotates, and the sensor does not burn - the sensor is broken.
In the absence of devices, disassemble the manual tramber. The drum of the trambler should not touch the Hall sensor. Sensor Check for the serviceability of the wires and the connector. Everything is respected, but there is no sparks? Replace the switch. If in this case does not spark, the ignition coil has failed. This is a rare phenomenon, but it happens.
In the presence of a spark on all elements, we remove the air filter cover and try to start. If the car started, it means that the filter clogged, and there is no air supply to the carburetor. Does not want to start - remove the filter and unscrew the hose leading from the fuel pump to the carburetor, and rotate the starter.
Still not start? Unscrew the candles. If they are filled, wearing on fire. The motor must start in 95% of cases.
With the onset of winter, most carburetor machines brings their owners. Not exceptions are the carburetor VAZ 2109, which are poorly repaid on the cold. The reasons for such a start can be a lot. This article will consider the most common reasons why carburetor VAZ 2109 is started on cold poorly.
Before making certain conclusions, you need to make sure that the driver correctly fulfills the requirements for the launch of a cold engine. For these purposes, carburetor engines have manual throttle control drive. Without using this mechanism, run the car, especially in the cold time, is quite problematic.
You need to start the engine in the following sequence:
- Open the hood and swing up the fuel manual pedal of fuel pump
- Pull the arm of the air damper control handle
- Drink gasoline to the collector of the accelerator pedal
- Without pushing the gas pedals, start the engine
From the first time, the motor may not work. But the second time should. You also need to focus on pumping gasoline gasoline pedal. The main thing is not to overdo it, otherwise you can pour candles and then the engine will definitely not start. If it happened, and the car did not start, then push the pedal until it stops, turn on the starter and, while it rotates, slowly release the gas pedal.
The starter turns badly on cold VAZ 2109
This is one of the most basic causes of bad ladies. There are two sides: the starter twisted or froze the battery. If with the first case everything is clear, then the second requires special attention.
With severe frosts, the battery is recommended to put into the house and put on charging, then the problems with the start will stay behind. But if this is not done, the task may be more complicated. To start you will need to turn on the Middle Light for a while - it will warm up the electrolyte. After that, you can try to include the starter for no more than 3 seconds. Each new attempt to launch the motor must be accompanied by pauses in 30 seconds, 1 minute and 2 minutes. Otherwise, the battery will pull to the end and instead of the trip will have to wait until the battery charges.
If in the summer you can pour oil with less viscosity or 20w40, then in severe frosts it freezes. Turn the crankshaft with frozen oil becomes very difficult, so the manufacturer recommends pouring motor oils with a viscosity of 5W40.
Another version of solving this problem is the use of preheating heaters, which are included in the 220 V network and heated toosol. Due to the heat transfer of the metal parts of the engine VAZ 2109 carburetor, butter becomes fat, and the motor can safely work even into severe frosts.
If the VAZ 2109 is poorly started not only on the cold, but also on a hot, then the problem can touch the system. The incorrect advance angle impairs the starting properties, because of which the launch becomes problematic.
Usually, the launch problems are observed at. In this case, you can see the black smoke from the exhaust pipe, the electrodes of the candles are covered with black nagar, and cotton is heard in the muffler when the accelerator pedal is pressed. You can try to rotate the rubber for several degrees or adjust the ignition from scratch. The problem should disappear.
However, too early angle leads to:
- Detonation;
- Engine overheating;
- Deletion of the mixture.
Problems of the power supply system VAZ
First of all, you need to check the air and fuel filter. If they are strongly contaminated, the engine is badly started on the cold. The design of the nine provides for two fuel filters located under the hood and machine and one air. If they are integer, then check the operation of the fuel pump.
Try to pump gasoline with a manual drive. If it is injected bad, the fault lies in the fuel pump.
Next to the queue - carburetor. Incorrect adjustment can lead to the machine will be bad for cold. Idling speed should not exceed 900 and drop below 700. Nagar on the ignition candlelight is unacceptable. Otherwise, the unit needs competent configuration.
Gas distribution mechanism
The latter is the valve. Before configuring a carburetor, you need to check the gaps in the valve mechanism. It is done on a cold engine, as the metal is expanding when heated.
Violations in gaps worsens compression. In this case, not only power is lost, but also deteriorates the launchers of the car.
These are the main reasons why it is bad for cold VAZ 2109. If none of these tips helps, it is better to contact the specialists.
