"Daewoo-Nexia" does not start: reasons, repairs

Perhaps every car owner, no matter what his car, knows that feeling of powerless disappointment in a situation where the car refuses to start. With this feeling are familiar and the owners of the car "Deu-Nexia". The engine does not start - this is a familiar topic for such cars. We will analyze the main causes of such failures and how to eliminate them.

Buying such cars, the future owner should clearly realize - this is a budget car and no more. Once upon a time there was a powerful advertising campaign on TV before the models were released: "I like the Uzbeks, they get well in the winter". Soon this phrase became famous and quickly went into people. And as it turned out, the truth is there. If the "Daewoo-Nexia" does not start after parking in the cold, then something just happened. Problems with the launch in the cold at the car there. But here there is one small nuance.

Deu-Nexia

The ancestor of this car is the "Opel-Cadet E", which was collected in Germany from 1984 to 1991. The first machines, manufactured under the license of "Opel", went off the assembly line in 1986. "Nexia" was sold in Canada and the US under the brand Cileo. In other countries, the model was known and bought as Daewoo Racer. The basis was taken "Cadet" engine. However, it was modified and modernized. This motor is highly reliable.

Trembler and Deu-Nexia

A huge number of owners of pre-styling models can easily challenge the opinion of the auto-hijacker from advertising that the various problems associated with launching into frosts are not a surprise. But "Daewoo-Nexia" does not start not only in the frost. Sometimes, just so suddenly, without serious reasons, suddenly refuses to start with the key. In this case, if the car is pushed, the engine starts and works easily with the accuracy of Swiss watches.

This behavior of the motor directly informs the owners of the malfunctions with the ignition system. In the case of Nexia, this diagnosis is also confirmed - the problems with starting from the key are in the trambler, and if the fault is diagnosed more precisely, then in the induction coil of the ignition distributor.

Over time, this detail can crumble literally in the dust. The manufacturer thought for a long time how to solve this problem, and found a way out. The company radically got rid of the ignition system along with the trambler. Automechanics say that in 2007 the 1.5-liter engine was modernized - unified with the engine from the family budget car "Lanos". In addition to the basic design changes, this modernization led to the fact that the tracer was not in the ICE. Instead, an electronic module responsible for the ignition is installed.

Typical reasons

The starter turns, but does not start "Daewoo-Nexia"? This happens quite often. Also there is an opposite situation - the starter does not twist. What's worse is difficult to find out even for experienced car owners. If there is such a problem, you need to check the most probable elements of the car, which could provoke this malfunction. This can be done on their own.

If there are problems with the starter, first check if there is a spark. Then look at the filter, battery and its terminals. It was not advisable to test the throttle. To start the motor, you need four elements: the presence of a spark, air, compression and fuel. If the "Daewoo-Nexia" does not start, first of all look at the candles.

Why there is no spark?

There are many reasons why there is no spark on the ICE. For example, it can talk about problems in the ignition module, the malfunction of the coil trambler in the pre-styling models, the crash in the sensor position of the crankshaft or the sensor position of the camshafts. Test the reading elements yourself, if you have easy access to them. Experts recommend using a diagnostic scanner - the latest "Nexia" equipped with an ECU, which can inform the owner of errors.

Next, check the fuse box and relay. So we will see that there is no spark for this reason. The most common option - the failure of spark plugs or high-voltage wires. This is a popular problem that can be easily solved. But if the plugs and wires are fully operational, you should check the coil and ignition module for operability.

The first can be diagnosed by detaching it from the wire. Then someone should turn the key in the ignition. Next, you should observe whether the electric current is suitable for the coil. If it goes, then the coil needs to be replaced.

Air filter

If the "Daewoo-Nexia" does not start, the starter turns, then check the air filter. In order for the engine to successfully start, it needs a certain amount of oxygen. If the air filter is clogged, then a normal supply of oxygen can be difficult. The resource of the element is 10 thousand kilometers. At the same time with the cleaner it is recommended to check both air intakes and ducts. They can be clogged with debris and leaves.

Fuel system

If there is a spark, the air comes in sufficient quantities, and the Daewoo-Nexia machine is not started, do not curse the manufacturer. Perhaps the fuel system is simply faulty. Even inexperienced car owners know that the engine will not run without fuel.

In the event of problems with the fuel system, the car will never start. Some car owners test the operation of this system using a syringe. It is filled with gasoline, and then the mixture is injected into the throttle. Then turn the key in the ignition.

Why is the fuel not supplied to the engine?

If the engine does not receive the required volume of the fuel mixture, then it is necessary to diagnose the gasoline pump and the pressure regulator. In the event that "Daewoo-Nexia" does not start, the reasons may be in fuel leaks, a clogged fuel filter and injectors. But most often it is a submersible pump. Below we will consider how to test it.

Checking the pump

Check whether the pump is working properly, you can do it yourself - it's easy. The first step is to determine the place where it is installed in the car (on the left under the passenger sofa). When you have access to the item, you can go to the diagnostics. Someone on the team should turn on the ignition for a few seconds. When the starter starts to function, the sound of the petrol pump will be heard. This indicates its serviceability. If there are no sounds, then the submersible pump does not supply power. Or it failed and requires replacement.

It happens that the pump is functioning, "Daewoo-Nexia" does not start, the starter is working normally. Then it is worth checking whether voltage is applied to the submerged element. This is done with a multimeter. The ignition key is turned and held in the "ON" position for three seconds. If the current goes, the multimeter will show it. Then check the resistance of the element. To do this, the multimeter is connected to the pump power contacts. This must be done, if at the time of engine start-up, no signs of the mechanism working are heard. Measurements are compared with the passport data. If the figures are very different, it is likely that the gasoline pump burned out.

If the starter does not spin

In most cases, this symptom indicates a discharged battery. And if the battery changed to a new one a few months ago, it's still worth checking it out. Diagnostics can be performed using a multimeter. It's not superfluous to make sure that the high-voltage wires are working, and the terminals are not corroded. Next, it is necessary to consider the malfunction of the starter relay. It is located in the distribution block of the car. When starting the ignition, the element should click. After you can check the starter itself. First, just hit the body lightly with something, then start the engine and listen. If the device is noisy during operation, then it should be replaced.

The engine starts and stalls

If the "Daewoo-Nexia" gets winded and stalls, there may be much more reasons. This is a malfunction of the immobilizer. Valves of idling are not clogged . It is possible that the car was refueled with bad gasoline, and a poor-quality oil was filled in the engine.

Conclusion

So, apparently, there are a lot of problems with this Uzbek-Korean car. It should also be taken into account that with the Uzbek assembly the machine is equipped with poor-quality wiring. And with it, the owners have problems on an equal footing. But if you take into account the price of these machines, then you can close your eyes to all these nuances. Cars are easily repaired in the garage with their own hands.
