To use the engine needs air, spark, fuel and compression. The disappearance of any of these four components is the reason because of which it is impossible to start the engine. Resuscitation gasoline engine starts by removing the air filter housing. At the same time open access to clean air motor and comes complete overview of the carburetor. Wet from the oil filter element is one of the reasons due to which the engine could not start the engine because the air is very difficult to pass through the wet and dirty filter. And this leads to pereobogascheniyu fuel mixture and spark plugs are filled with gasoline. Then you check the status of the battery. Severely depleted battery will not be able to create the torque needed to run the motor, so a weak battery should immediately put in charge. While a charge, you should remove all the spark plugs to check their condition. Wet or covered in black soot candles greatly reduces the probability of starting the engine. In wet weather, cold on the inside lid ignition distributor is going to water and mildew that may cause the alternate ignition in the cylinders. After removing the air filter, battery, replace the spark plugs and wipe clean with a dry cloth cover most of the ignition distributor of engines normally start. Immediately after starting the engine to check oil pressure, battery charge voltage, the circulation of the coolant. If the motor does not start, you need a more thorough check. To check the quality of the spark arrester is best to use. This thing is a simple standard candle with an increased maximum gap between the electrodes. By the candle fastened a great time of "crocodile". The candle fits validated high-voltage wire and "alligator" is attached to any available media at the engine. When you rotate the starter motor gap between the electrodes should slip smoothly spark blue. The gap between the electrodes, candles should be 5-7 mm. The presence of a spark is first checked at the central high-voltage wire from the ignition coil to the distributor. Then checked by high-voltage wires after the distributor. The most common reason for lack of spark ignition systems on the contact may be the wrong breaker contact gap or no gap. Among other reasons, lack of spark, the following faults: the breakdown of high voltage insulation slider or cover ignition distributor, ignition coil is faulty, the capacitor operates intermittently, contact breaker strongly burn, loss of power supply wires of the ignition system (ignition), the wet candles, burned-out cores in high-voltage wires . The electronic ignition systems is experiencing the most severe load switch, so its premature demise is not surprising. Pulse generator in electronic systems can be Hall-effect sensor, inductive sensor or an optical oscillator. The main task of the pulse generator - send a signal to the switch at the right moment in time that he started to discharge a spark plug. Failure of the pulse generator or breakage of wires to power is the cause of the lack of spark. The pulse generator can be placed on the flywheel ("Renault") to the camshaft ("OPEL") and distributor ("Lada" with an electronic ignition system). On engines where the pulse generator is located on the camshaft, the reason no spark could be a timing belt break timing. To test the need to remove the cover of the distributor, connect the central high-voltage wire to the surge and krutnut motor starter. The slider valve should rotate with the camshaft. If the slider does not rotate - can be broken belt or timing failure clutch actuator valve. Part of the reason for which the motor will not start, is the improper installation of high voltage wires in the order of the cylinders. When you connect the wrong engine may not start the engine, or start the engine, but it will not work all cylinders. It will be seen on regular cotton in the muffler, and while pressing the gas may be popping out of the carburetor with the release of the fire. When scrolling, the starter motor may experience sneezing, or a chaotic claps from the carburetor. This is a sign of incorrect connection of high voltage wires. When connecting wires, but the order of the cylinders, you should always know where this is the first engine cylinder and in which direction to rotate the slider. This information is in the automotive references. To learn about the procedure without reference to an unknown location of cylinders you motor, there are many different methods. One of them - instead of the spark plug screwed on all cylinders blowing. Purge - a simple device in the form of a tube length of 30-40 cm with a metal tip, which is cut candle carving. This device lets you know whether closed valve in the cylinder at the moment. If the cylinder is blown - valve open, if not blown - the valve closed. Rotate the engine or using a ratchet driving wheel with the inclusion of a direct transfer, you must manually rotate the motor in the course of its operating speed, with a sharp hissing sound will be audible air from each cylinder in turn, at the time of the compression stroke. This sequence of hisses and will comply with the order of the cylinders. And if you withdraw before the turning of the engine ignition distributor cap, then the position of the slider, you can determine which slot in the lid meets the hissing at the moment the cylinder. On many cars instead of the distributor of ignition system is used with bipolar ignition coils. The main body of the coils indicated their slots to each cylinder. Purging can also be used in the diagnosis of the state of the cylinder-piston group. You need to adjust the piston in the cylinder checked the position of TDC in the compression stroke, put the gearshift in first gear and tighten the parking brake. Then through purging of the cylinder must be submitted by the air pressure of 2-3 kg / cm. Ideally, the air must be quickly out of the combustion chamber checked the cylinder. Fault is determined by the hiss of air: the hissing in the carburetor - open or bankrupt inlet valve; hiss in the muffler - closed or went bankrupt drain valve, pipe hiss audible in the crankcase - the piston rings or in poor condition, the hiss of a neighboring cylinder or swirling the liquid in the cooling system - broken cylinder head gasket. If the ignition system is working properly, but the engine still will not start - need to check the flow of gasoline into the carburetor. A quick check is pouring gasoline into the carburetor primary chamber. For this it is convenient to use a medical syringe of 20 mililitrov. If, after pouring gasoline engine wound up and immediately fell silent, then there are problems with supply of gasoline. To start a cold engine on any carburetor has a fuel-enrichment system. Reliable starting a cold engine depends on the correct operation of this system. Increased demands on the integrity of this system arise from the onset of frosts. If the summer is easy to start up the engine even with a faulty system cold start in the winter it is very sensitive to the smallest error in the system. The most common faults of a cold start are pereobednenie mixture, which is manifested in the incomplete closure of the choke and pereobogaschenie mixture, which is manifested in the untimely opening of the choke immediately after starting the engine. When the engine is put pereobednenii and then stalls. When pereobogaschenii motor starts, runs good, but after a few seconds starts troit, turns warm down. If at this point not to help open the air vent on the value of start-up clearance, it will flood the spark plugs and gasoline engine stall. Helping to open the air vent, we must find her a position at which the motor speed will be highest and stable. The task of the starter is that on a cold engine before running completely block the air passage and the valve slightly open up the throttle. After starting the engine choke gradually reopened for a small gap, called a trigger. This is a necessary condition for stable operation of the engine at high speeds of heating. The gap opening the choke depends on the design of the carburetor and engine capacity. Starting the gap can be adjusted and this can be done routinely on a cold engine. In many carbs to open the choke to start the magnitude of the gap is a vacuum device. Immediately after starting the engine there is a vacuum, which, through the damping orifice affects the diaphragm vacuum starter, the diaphragm moves the valve opens and the thrust on the value of start-up clearance. Damaged diaphragm can not move the traction valve will remain closed and the motor will not run stably at the speed of heating. During repair the carburetor should pay attention to the integrity of the diaphragm so as to regulate the start-up clearance of the damaged diaphragm useless. During the rotation starter motor need to pay attention to the sound, which rotated the motor. If there is compression in the cylinders, the sound is the rhythmic turning. But when the compression for some reason disappears, the sound of cranking the engine becomes smooth without pulsation. Compression in the engine may disappear momentarily only in case of rupture of a belt or chain timing. In addition, the instantaneous disappearance of compression can be caused by a sharp increase in oil pressure in the lubrication system on the motor, which uses hydraulic lifters thermal clearances on the valves. The sharp increase in oil pressure is the result of seizure relief valve in oil pump. The pressure may increase once in two or three times, with an excess of oil fills the internal volume of hydraulic and creates a situation in which the valve will not be able to close completely in the compression stroke due to increasing the size of joints. Most often this happens during start-up motor, but can sometimes occur during the ride. The disappearance of the compression does not necessarily occur in all cylinders. This can happen in two or three cylinders, but this will be enough to ensure that the motor could not start. Compression in the affected cylinders can be 2-3 kg / cm. This problem occurs when operating the motor without the timely replacement of oil or oil change is performed without pre-washing the oil system. Increased pressure in the system may occur from use of oil more viscous properties than those required by the manufacturer. There were times when as a result of increasing oil pressure burst thin tin oil filter housing. When timing belt breakage stops rotating camshaft engine valve, and some remain permanently open. With a sharp increase in oil pressure camshaft rotates, but also some of the valves remain open. Therefore, even the sound of the starter motor rotation can be in both cases. Service center personnel actions at break belt obvious. But when the belt is safe and correctly installed, and compression had disappeared, the situation often causes confusion. Especially when the victim vehicle has low mileage and is in excellent condition. One of the signs by which to judge the status of permanent closure of inlet valves is typical of a regular "pshikanie" air diffuser of the carburetor, which occurs during rotation of the motor starter. To hear it is necessary to remove the turning of the engine air filter housing. Before measuring the compression necessary to remove all the spark plugs and turn the power off the ignition system. To return to the good cylinder compression, reduce the pressure of hydraulic and lubrication throughout the system. To do this, do not necessarily dismantle the engine. For starters, you can try a simpler method. All spark plugs must be unscrewed. Next, you need to take action to eliminate the possibility of a spark in the ignition and disconnect the fuel supply to the cylinders. Posting to jack one of the driving wheels, include a direct transfer and begin to turn the wheel while moving. If the car an automatic gearbox, the motor will rotate a ratchet. Rotate to leisurely. In the slow rotation of the crankshaft oil shocks affect the relief valve in oil pump, and this increases the probability of release of the pressure reducing valve from sticking. Camshaft alternately click on the expansion, squeezing out excess oil from them. In order not to create too much grease in the system pressure can temporarily loosen the oil filter and try, if possible, to temporarily close the hole with his finger, which yields oil. It also accelerates time wedging pressure reducing valve in the oil pump. To collect the resulting oil tank should be set. The rotation of the motor starter or towing a car with a gear will further increase the oil pressure and you have a real opportunity to bend the valve! After 10-15 minutes of slow rotation of the motor can check the amount of compression in the weak cylinder. In most cases, compression vyrostaet in two or three times and it is possible to start the engine. The slow rotation of the motor for 20-30 minutes - it is an effective method of resuscitation, but not always helpful. There were cases when the discharge valve starts working only after removing and washing the oil pump. Heavily clogged exhaust catalyst greatly complicates the start of the engine, and a full plug in the muffler did not give the possibility of engine start. Signs of severe clogging of the catalyst or exhaust systems are listed in other sections of the site. There is only worth mentioning some features of the motor with a clogged exhaust system. Motor can start and work well on idle. But when pressed on the gas pedal is a slow increase in speed and at the same time of the air diffusers are beginning to take off the carburetor up small droplets of gasoline with air to a height of 5 to 15 cm Motor poorly responsive to throttle and speed can not rise above average. When fully depressed the throttle of the carburetor can hear the roar of a characteristic that is added to the sound of the motor. It should be noted that the same phenomenon can be observed by improper installation of the belt timing. In some cases, crashes up droplets of gasoline from the carburetor can only occur when engine speeds close to maximum. This indicates a slight contamination of the exhaust system. Therefore, during the monitoring visit is not necessary to install air filter on the carburetor. After a short drive to the maximum engine speed immediately after stopping the car should quickly open the hood and look at the place, which was located directly above the carburetor with a closed hood. If at this point can be seen the wet spot gasoline, so in the exhaust system is clogged. To pinpoint the culprit of the fault, it is necessary to unscrew the flange from the exhaust pipe of the exhaust manifold for about a distance of 10 mm. This distance would be enough for the free passage of exhaust gases and then take control trip by car in 10 minutes. Trip without killing the system should be carried out outside the city limits. If the cause was a clogged muffler, it is now, virtually no silencing of the motor is fully stabilized and the power of the car would dramatically increase. Reasons for challenging a cold engine are somewhat different from the causes of the difficult start of the heated engine. The main difference is that for a cold engine requires a richer mixture, ie more gasoline. A warmed-up engine to start working the mixture should be the poorer.

Reasons for challenging a cold engine are somewhat different from the causes of the difficult start of the heated engine. The main difference is that for a cold engine requires a richer mixture, ie more gasoline. A warmed-up engine to start working the mixture should be the poorer. The importance of this difference is well noticeable in hot weather, when temperatures under the hood rises above 100 ° C. After stopping the engine intake manifold is gasoline, which did not have time to get into the combustion chamber. While not moving, gasoline begins to evaporate rapidly, filling the vapor space of all inlet manifold to the air filter. These pairs are added to the evaporation of gasoline from the carburetor float chamber. The strongest concentration of gasoline vapor is formed in about 5-8 minutes after stopping the engine. In the process of cooling the engine vapor concentration is gradually reduced. But trying to run a hot motor in the hot weather in 5-10 minutes after stopping may end unsuccessfully if the actions of the driver will be wrong. When scrolling the starter to the engine cylinders is pumped gasoline from the carburetor and a rich mixture of gasoline vapor from the intake tract. The share of fresh air in this part is very small. Too rich a mixture of gasoline just does not burn. As is known, the optimal (stoichiometric) ratio of the mixture is about 14.7 parts by weight of air to one part by weight of the fuel. It is believed that the engine can operate, albeit inefficiently when air / fuel ratio from 22:1 to 8:1, and. Therefore, the mixture ignited and the motor runs only when the in-cylinder air will flow in the required ratio with the fuel. To speed up the process of ventilation intake manifold, it is necessary when scrolling the starter to keep the gas pedal is pressed. If the motor does not start, gas pedal does not need to go. There should be a starter a breather and then try starting. All this time the throttle must be fully (or at least partially) open. Repeatedly pressing the pedal will only worsen the situation, because every time you press the gas pedal accelerator pump is activated, which adds an extra header portion of gasoline and cylinders of time ventilation mode is increasing. Starting superheated gasoline engine without opening the throttle is a flagrant violation and may result in a complete discharge the battery. When the engine starts and begins to gain momentum, it is necessary to limit the promotion of the engine, but at the same time do not put too low a speed as the engine may stall. The engine operation is stabilized only when the clean air will replace the rich mixture. In this case there may be a short black smoke from the exhaust pipe. In some cases, you can even remove the air cleaner cover to speed up the process of ventilation. Wrong actions of the driver when starting a hot engine carburetor lead to complete depletion of the battery and pouring gasoline spark plugs. Difficult start a hot engine can be caused by a decrease in the level of lead in gasoline. Additives such as isobutane, which is used as a substitute for lead, are more volatile and less ignited on the hot engine. Therefore, start the engine warmed up can take up to 5 seconds, and it is considered normal. Sometimes, removing the top cover of the carburetor on a hot engine can be seen as boils and bubbles gasoline in the float chamber. Behaves gasoline with a low boiling point. At the same time of the injector accelerator spontaneously under the influence of the vapor follows petrol. All this leads to excessive intake tract pereobogascheniyu on a hot engine. The reasons causing pereobogaschenie intake tract on a hot engine is stopped, you can add a dirty air filter, high pressure fuel pump and pull the control knob choke.
