Coils can be weird like that. And also the high-voltage wires and tips need to be inspected and ringed, the resistance checked. tips often like to die. Since the spark plugs may be wet if the coils' brains are cut off. and by the way, where did the order 1234 come from when it should be 1342? Where are the cars anyway? Otherwise I can drive up and take a look, maybe I can help.

I looked at the photo on the drome. If the wires are connected in the same way as in the photo in the ad, then the wires of cylinders 1 and 4 need to be swapped on the coil. and then reset the errors (if I remember correctly, on Mikasa it is enough to remove the terminal from the battery for a couple of minutes).

Well, you have to watch it live. and the teeth will be exotic, they are fleshy and the pulley from below should be covered with a shield, in theory, no rubbish from the road should get on it.

By the way, I also remembered one sore that happens in the 406 family. For some time (a long time) the crankshaft pulley was not installed in one piece, but with a rubber damper. and it happens that this damper comes off and the part with the teeth rotates relative to the pulley hub. In this case, the engine will just sneeze, fill the spark plugs, and then an error will appear on the DPKV and will not start. It is easy to check: remove the belts from the pulley and try to turn it by hand by the ring gear. If it turns, the pulley needs to be replaced. I recommend replacing it with a solid one, without a damper.

Causes

Not for various reasons. Some of them are related to the time of year, while others are related to wear and tear. This problem can also be caused by the negligence of drivers who are careless about the maintenance of the power unit.

So, if not, there may be several reasons:

malfunction of fuel system components;
problem in valves and cylinders;
malfunctions in the ignition system;
breakdowns in the starter and battery;
air supply;
sensors and control unit.

Why doesn't the injection Gazelle 405 start? Main reasons

There are different problems with cars, but the Gazelle 405 injector does not start
most often. Drivers begin to rack their brains, but sometimes a solution to the problem is still impossible to find. Now we will look at several of the most likely breakdowns during which the car will not start.

When this happens, you first need to look at all the wires, spark plugs, rail pressure and injectors. Most often, the Gazelle 405 injector does not start because of the spark plugs, so just replace them. But sometimes problems arise that are more serious than candles.

Some, when the Gazelle 405 does not start, immediately change the coolant temperature sensor. The fact is that the engine may overheat and it is because of this that it does not want to start.

Try changing the sensor and the cooling will return to normal. In any case, the most reliable option is to take it to a car service center. There, qualified specialists will quickly deal with the breakdown and tell you what was wrong with the car. You will know in the future what exactly will have to be repaired.

Common Causes

The Gazelle 405 injector does not start for various reasons. There could be a hundred of them, or even more, since there are simply unrealistically many details. However, injectors and spark plugs

. If the latter can be bought at any auto parts store, and even a not very experienced driver can replace them, then problems may arise with the former.

The fact is that it is very difficult to determine that in such a situation in the Gazelle 405 it was the injectors that broke

They are often the last thing thought of.

, so a lot of time is lost diagnosing the breakdown. But there is another option - problems with the injector. Fortunately, it doesn’t always need to be repaired; sometimes all you need to do is wash the part and the car will start. In any case, you will be very lucky if the breakdown is not serious, since the Gazelle 405 can take forever to repair and still not understand the reasons for the breakdown.

Car service will help

If you decide to contact a car service, first of all carry out engine diagnostics. Few inexperienced drivers understand the cause of the breakdown. At the same time, the Gazelle 405 may not start for various reasons, and some of them can be resolved on the spot.

When you finally take your car to a car service center, at least consult with its employees; most likely they will tell you what the problem is.

It is very important to know absolutely everything about your car.

to protect yourself on the road and do extra work. Sooner or later, any part can break, but it will be better if you are prepared for this.

Special cases

In addition to all of the above, other adventures happen with the Gazelle 405. Many drivers do not notice how the chain on the engine jumps. Accordingly, the engine refuses to come to life until the chain is in its place.

Your task is simply to open the hood and check if the chain is in order

, if not, then put it in its place. This procedure will take you 10 minutes at best, but you will be able to start your car. Otherwise, the Gazelle 405 injector does not start due to other problems.

It is quite difficult to answer this question, so we have simply listed for you several of the most common breakdown options. You can get an accurate answer only after a thorough diagnosis. It is at this stage that you can find out the reason why the car refuses to start. Therefore, do not rack your brains and it is better to contact a car service center.

Yes, you will spend money, and most likely a lot, but at least you will be able to continue to quietly drive around in your gazelle.

Fuel cells

It is worth understanding that almost all elements affect the starting of the motor. For example, since the Gazelle was produced both with carburetor and injection, the injection elements will be different. This means that the reasons for possible breakdowns will not be the same.

The Gazelle-406 engine is an injection version of the vehicle. It has injectors installed, which can be the source of the problem. If cleaning has not been carried out, then most likely the injectors are dirty. To fix this, you need to remove the parts from the machine and send them for cleaning. If, during the process of restoring the functionality of the injectors, it turns out that the product cannot be repaired, then it must be replaced.

A fuel pump malfunction may be due to a breakdown inside the module. To check whether the pump is pumping, you need to get behind the wheel of the car and turn the ignition key to the second position. In this case, a characteristic noise should begin from behind, which will mean that the pump is in working condition.

Particular attention should be paid to the condition of the fuel filter. According to the service manuals and recommendations of the manufacturer, the fuel filter element must be changed every 40,000 km. If this is not done, the filter becomes clogged and does not allow fuel to pass through properly, which results in a lean mixture in the cylinders, or gasoline does not get in for ignition at all.

Recently, literally 2 days ago, I touched my friend’s head. I had the same crap as you. The engine was spinning at idle as if without spark plugs. They measured the compression, it showed 0, they threw off the head and after troubleshooting, they replaced the valves on all 4 cylinders. valves hang on our 406 engines

it was such bullshit. The crankshaft sensor died... it was a Chinese one... then I installed ours... I've been driving it for several months now and everything is fine... if the chain had jumped, there would have been popping noises in the silencer and in the intake... it happens that the buttons on the left side under the diagnostic connector die. change both... as far as I know they are for brains + injectors and a fuel pump... if the relay is dead. at least it won't start. I’ve already had this happen a couple of times... I’ve replaced 4 of them in three years...

Result: Crankshaft sensor Relyushki under the diagnostic connector

This is a DTOZH for everyone! Not long ago there was the same garbage!

Self-diagnosis shows code 12, which means it’s not the sensors...

Don't even touch the sensors yet. Were there any misfires in the engine before, or was there an incomprehensible knocking noise sometimes?

Well, there wasn’t a knock, under load it made a noise like a tractor, and then nothing

The valves were actually stuck. when you open your head, look carefully at the valves; there will be stripes on them from the impact on the piston. When they started rubbing the valves, the large plates were not completely rubbed. Because of this, the entire set was replaced

In general, I disassembled the timing belt and the lower chain broke. How to check if the valves are bent? Does the head need to be removed?

In theory it shouldn't bend. Try to assemble the timing belt and measure the compression.

Today I'll start collecting as I go. There was no money (

Well, there wasn’t a knock, under load it made a noise like a tractor, and then nothing

Why did I write so that you don’t dig deeper and look for the reason somewhere else in the bowels of the engine. and it is not necessary that all of them will have a stripe. Maybe one or two, but it is advisable to rub all the valves and change the valve seal. and be sure to pull them out of the guides, clean them and repair them

Self-diagnosis shows code 12, which means it’s not the sensors...

Valves and cylinders

Quite a few motorists monitor the condition of the power unit. As you know, wear and tear does not spare anyone or anything, and accordingly, burnout of valves and pistons can lead to the fact that at first the engine begins to start poorly, and then stops altogether.

The second nuance is the high degree of wear of the valves, which is why they do not fit tightly to the seats. Gasoline drips through the cracks into the cylinders. It turns out that there is an overflow of fuel, and since the spark plugs are filled, the power plant does not start due to the lack of a spark.

Ignition system

Spark plugs and high-voltage wires directly affect engine starting. Accordingly, breakdowns in the elements will cause a failure of the entire system. To check spark plugs, a special stand is used, although you can check it the old fashioned way:

We unscrew the candle from the well.
We connect the armored wire.
Connect the spark plug body to ground.
We try to start the engine.

If everything is in order with the spark plugs, then there will be a spark between the contacts. If the part is faulty, then there will be no spark, and accordingly, the element must be replaced. Checking armored wires is quite simple. All elements are removed from the car and measured by a tester. The resistance on each high voltage wire should be 5 ohms.

Problems in the ignition system

In the Gazelle ignition system with the ZMZ 405 engine, the weak point is the coils and spark plugs. They most often become the reason for the inability to start the engine.

When the spark plugs are destroyed, they are no longer capable of producing a normal spark. Defects in the electrodes make it difficult to start the engine. Even if you managed to start the engine, it stalls after a little work. To fix the problem, it is recommended to replace the entire set of spark plugs.

Poor starting on cold Gazelle 406 injector

Today -14, started only with the gas pedal. When hot, it starts without the gas pedal, but it turns several revolutions longer compared to a serviceable Volga 406i. Otherwise the engine runs like a clock. I understand from reading the conference archives that the temperature sensor is to blame, I want to try transferring it from the Volga.

Which temperature sensor needs to be replaced? The one in the receiver that measures the air temperature? Or is it a sensor in the thermostat housing?

Thanks in advance, Alexander (Gazelle 406i and Volga 406i).

PS Forgot to indicate: Gazelle, engine 4062, Mikas 7.1 film, 590 firmware.

It’s not a fact that the sensors.. It could be spark plugs (BB) or problems with freezing of the IAC (DZ). And when you operate the pedal, you simply control the speed yourself, and not MIKAS in XX mode

nope.. Look. If so, then there is NO heating of the DZ yet (the antifreeze is still COLD). And when it starts up, does the “air flow” “suck out” EVERYTHING with black smoke? Wow. If there is LOW oxygen (for example, the IAC is malfunctioning). That is what will happen - RE-ENRICHMENT.

Briefly speaking. I would still look at the “IAC steps” during startup and during operation. Another option is injector glitches

Try pumping it up three times and starting it! 1 temperature sensor 2 pump is dying!

Try starting it with the gas pedal depressed. To be honest, there can be many reasons: injectors (flow), pump (pressure), jot (new, it’s not a fact that it’s working or not for your brain www.drive2.ru/l/5303392/), ignition angle, quality of gasoline, rxx ( try flushing), voltage on board (try to throw a wire on the coil with the + battery when it’s cold and start it like that, when you connect the ignition will turn on, that’s how it should be!), spark plugs (gap of spark plugs), air filter (unlikely, but still) , timing belt (stretched chain), try wiping the headlights before starting))) (HUMOR), maybe I missed something else, someone will add!

Thank you for your response, everything that you listed this year, everything was installed new, you understand, the mileage is 356,000 km... it starts but not the first time, the second or even the third... on a warm engine with half a turn... by the way, what kind of OZ should Mikasa 11 have? The ZMZ 405 won't start at all with the pedal depressed! If the forces were flowing when the ignition was turned on, popping noises would be made in the combustion chambers! this is not the case. Idle speed is perfect 800 rpm. Most likely the DTOZh stuck the wrong one!

On Mikasa I can’t say, it seems to be programmed there from the factory because it doesn’t change the advance angle from the onboard one. But on Soate it changes for me. Try to play around with the camshaft sensor, it also sometimes gets weird and there is no way to check it and it won’t give an error until it shorts out, it was like seven years ago, at idle there seemed to be little shaking and every other time it started normally, who knows? . you can check its integrity through resistance with a cartoon just like a jot, but I don’t remember the parameters ((, a guy suggested it a long time ago, since they are not exchangeable, he checked it right away from the cash register, out of 10 only 5-6 are normal .

jot Sensor resistance: 24…27 kOhm just in case

Battery problems

If the Gazelle does not start, then you should start searching for the impossibility of starting the engine with the battery. If it is insufficiently charged, the starter does not have enough energy to turn the crankshaft. In this case, a significant drop in the on-board network voltage occurs. The traction relay starts to click, but the engine cannot start.

The situation with starting the engine with a discharged or old battery is aggravated in cold weather. There are two reasons for this:

engine oil thickens in the cold and it becomes more difficult for the starter to crank the crankshaft, which causes increased starting current and greater battery energy consumption;
When it's cold, the chemical reactions of the battery slow down and the battery becomes able to deliver less charge.

In winter, both of the above reasons overlap each other. Starting becomes especially difficult when cold. Under unfavorable conditions, the car may completely refuse to start.

With a discharged battery, many car owners start their Gazelle only with a pusher, but there are other ways, the main ones being:

start using ROM;
“lighting up” from another vehicle;
charging the original battery with a nominal or increased current and then starting the power unit.

A situation with a discharged battery does not require special attention from the car owner if it occurs only once. It is enough to recharge the battery and you can continue to operate the machine as before. If the battery dies often, then it is necessary to diagnose it. Based on its results, a decision is made on the method and feasibility of restoration work. In some cases, it is more rational to purchase a new battery.

If the battery shows full serviceability, but dies in a short period of time, then the on-board network must be checked. It may contain short circuits and high leakage currents. If they are identified, you should not delay troubleshooting. Prompt resolution of problems will eliminate the risk of a car fire.

The integrity of the battery case directly affects the success of starting the power unit.

The presence of through cracks and other similar defects leads to the loss of part of the electrolyte. The battery's ability to deliver starting current and energy is significantly reduced. To diagnose the problem, just carefully inspect the case. If any damage is detected, the car owner is faced with a choice between carrying out repairs or purchasing a new power source.
