Winter is perhaps the most insidious time of the year for motorists. Indeed, in addition to snowfall and difficult road conditions, sometimes it is simply impossible to start a car. And it doesn’t matter if the carburetor is an engine or injector.
No one is safe from such a problem, even the owners of new cars. And today we will tell you how to start the injector in the cold in various ways.
Causes
One of the most likely reasons that the car suddenly refused to start is a malfunction in the fuel system. Several factors can be noted here:
- Poor fuel quality. For our realities, this is quite common. However, if gasoline has a large percentage of water content, this can significantly affect the operation of the fuel system and the whole car.
- Contaminated nozzles or fuel filter. From time to time, both elements tend to attract and absorb dirt, so their condition should always be monitored and inspected at least every 5 thousand kilometers.
- Lack of pressure in the fuel lines or a malfunction of the fuel pump. Also, the fuel pressure regulator itself may become unusable in the system.
- Wrong proportions of mixing air with gasoline (air-fuel mixture). This may indicate a clogged air filter or a defective throttle. It may happen that on the latter at a low temperature the dirt simply froze.
Also, the cause of poor engine starting in winter can be hidden in the ignition system. First of all, you need to check the battery charge - it is he who has the property to discharge at the most unpredictable moment. Also, the problem may be hiding in gasoline-filled candles. In this case, they must be unscrewed and dried on a hot surface. Less often, failure is hidden in the disturbed timing of the timing distribution or in compression of the cylinders.
How to start the injector in the frost by the method of "lighting"?
This method has nothing to do with the car cigarette lighter. Everything is much simpler - this method involves starting the internal combustion engine using the battery of another car.
How to start the injector in the cold? In order not to accidentally burn an electronic control unit, the cost of which reaches 50 thousand rubles, you must adhere to special rules:
- Using this method of starting a car, it is strictly forbidden to use wire wrapping or connecting wires by hand. The cords must have special clamps, otherwise it is possible that after such “lighting” the battery will burn out or the entire on-board network of the machine will close.
- You should not gass a lot at this time, since increased engine speeds significantly heat the generator.
- Before starting the injector in cold weather, pay attention to the quality of the insulation of the wires - they should not have cracks or other deformations outside.
- Observe the polarity of the connection. If you confuse the "plus" with the "minus", the consequences may be the same as in the first case with cheating.
- After starting the engine, allow the cars to work in pairs for 2-3 minutes. Next in order, disconnect the negative terminals first, then the positive ones.
Folk ways
Some motorists advise to turn on the dipped headlights for 20 seconds before starting, and then turn the ignition key. Thanks to this action, we will initiate certain chemical processes in the battery, and by the time the starter is scrolled, the battery will already be in a pre-warmed state.
How to get an injector "from the pusher"?
This method of starting a car implies that your car should start on the go. To do this, just ask someone from your neighbors to push your vehicle.
Before telling the features of this starting method, we note that it is suitable only for cars with a manual gearbox. If you have an automatic transmission, you can start the injector in the cold only in the two ways described above.
So what needs to be done? First, the car is put in 3rd gear, after which you get behind the wheel, and your neighbor begins to push the car forward. Once you have traveled 5-6 meters, you can safely turn the ignition key. As practice shows, this method works even with a discharged battery.
Starting fluid
However, it is believed that the previous method should be applied as the most recent. First, motorists recommend trying to “light” from another car or use a special starting fluid to start the injector in a cold period of time.
Note that this starting substance can also be used for carburetor cars. In this case, the air filter cover is removed and fluid is injected into the carburetor.
How to use it?
On injection engines, this works a little differently. How to start the injector in the cold in this case? Here, starting fluid can be injected into the air manifold. But before that, it is necessary to remove the filter pipe. After injection operations, the nozzles are put back in place.
After that, we boldly start the engine. In most cases, this method also helps a lot, but “just in case of a fireman” remember the principle of starting a car “from a pusher”.
So, we found out why the injector does not start in the cold, and how to properly start the car engine at low temperatures in various ways. Remembering them is very simple, and they themselves are simple.
