Do not start "Ford Focus 2": possible causes and solutions to the problem

"Ford Focus 2" - very reliable cars, and owners are very rarely faced with any problems in the process of their operation. However, there are various minor troubles. One of them - the driver turns the key in the ignition, but nothing happens. The car does not react - Ford Focus 2 will not start. Let's try to understand the reasons for this behavior of the car and learn how to solve a similar problem.

Looking for a problem, "dry" the candles

In most situations, when the engine does not want to start, problems can occur in three systems. This is the engine power, ignition, as well as a starter or motor start system. But before you open the hood, diagnose and lead the search for breakdown, you must try to apply a special approach to starting the engine. To do this, push the accelerator pedal all the way to the stop, and after that turn the starter key. Pressing the accelerator pedal will result in the fuel mixture not falling into the cylinders, and the excess fuel from the combustion chambers will leave, due to which the spark plugs dry out. Sometimes an overdose of the mixture occurs. This method sometimes helps to fix the problem. Now, you should try to start the power unit in the usual way. It is enough a few unsuccessful attempts to start the engine, so that the candles are filled with gasoline. If the "Ford Focus 2" does not start anyway, then we need to look for the problem more deeply. About how to do this, - next.

Problems with the starter and starting system

Often, one of the most popular reasons for starting a car engine is precisely this launch system or the wrong operation of the main device - the starter. There are several typical faults and signs of breakages. You can solve the problem with your own hands.

The starter works, but the motor does not start

Do not start "Ford Focus 2" and the starter does not show any signs of life? This situation can occur due to a burnout of the corresponding fuse in the unit. This element is labeled as F-13. The unit is located under the hood of the car. Also, the problem is a poor electrical contact or short circuit in the power supply circuit of the starter. The traction relay often fails. Another common problem - "Ford Focus 2" does not start, the starter spins up the crankshaft, but distinctly audible clicks are heard. These sounds indicate various troubles in the winding of the traction relay. Still it is connected with a weak charge of the accumulator or bad (and more often - simply weak) contacts in the wiring. If the starting device rotates the crankshaft, the anchor works confidently, but the flywheel does not rotate, then here it is necessary to search for damages in the flywheel itself. Also, there are breakage of the drive rings, problems with the levers or with buffer springs. Often, the clutch housing is poorly connected to the starter.

When the launcher function properly, but the armature does not practically feel, the rotation is slow, it is necessary to pay attention to the battery. If "Ford Focus 2" does not start, the starter rotates this way, then there is a 100% problem with the battery. Still need to pay attention to all the connections, the state of the contacts on the traction relay and the collector. Rarely a failure occurs when the starter continues its rotation even after the engine has started and running. This is connected with the malfunction of the crank case. Also connections or closures in the traction relay are possible. If there is such a problem, experts recommend to muffle the motor.

If there is a situation when the "Ford Focus 2" does not start, the starter turns, then car repair experts recommend replacing the fuse in the unit, check the charging of the battery and also make sure that the starter contacts are securely tightened.

Check candles and spark

If the ignition coil circuit is OK, then check if there is a spark on the spark plugs. To perform a spark test, a high-voltage wire is removed from one of the candles. It inserts a known good part. The candle must be brought to any metal bodywork. Thus simultaneously it is necessary to turn a key in the ignition lock (the assistant is required). The contact between the mass and the spark plug should be good, because with increasing the gap there are risks of failure of the engine control unit or the high-voltage circuit of the ignition coil. This check should not take more than five seconds. If you rotate the starter further, the exhaust gas neutralizer will fail. And the battery itself will lose a lot of power. If there is no spark, the first thing to do is replace the high-voltage wires. If there is no current even after installing new wires, then replace the ignition coil - the problem is in it. When there is a spark, but it does not start "Ford Focus 2", it is worth replacing the whole candles.

Diagnosis of the power system

If there is no pressure in the fuel rail, this indicates that the system is malfunctioning. But before a breakdown is established, it is necessary to check the condition of the air filter. This is done very simply and quickly enough. If the filter is in its proper state, but the Ford Focus 2 is badly wound, then check the state of the electrical contacts. They are harnessed together. These are the injection system wires that are responsible for supplying fuel to the cylinders. Further, experts recommend checking the pressure in the fuel rail of the engine. But for this it is necessary to have a manometer. The device is connected to the fuel line. Then turn the ignition key and listen. If there is a slight noise, the gasoline pump is in working order. If it is not present, it is necessary to check directly the fuel pump, as well as its wiring. A defective gasoline pump is a common reason why the Ford Focus 2 is not started. Further, check if there is a fuel pressure. The level should be within 3 kg / cm2. At the time of measurement, the motor should be idling. It should be noted that the gasoline pump may not work if the fuel system has sufficient pressure.

The engine does not start in frost

If "Ford Focus 2" does not start in the frost, then it can talk about a discharged battery. Also among the causes can be identified breakdowns in the ignition distributor system. Possible damage or breakdown of high-voltage wires. Also check the ignition coil. However, the most common reasons are still the battery and the candles. If the starter turns, the gasoline pump works as it should, and "Ford Focus 2" does not start in the frost, then most often it's the candles that are to blame. In cold weather, they are filled with gasoline. After replacing the spark plugs, the engine should normally start.

Starts up and stalls

There are many reasons for this behavior. They can be associated with the malfunctioning of security equipment, immobilizers, anti-theft systems. The problem is also associated with a faulty or clogged idling valve. On the details of this valve, deposits form. They do not have the best effect on the throttle.

The next reason is banal - this is the quality of fuel. If you fill a car with a bad refueling, then very often Ford Focus 2 gets stuck and stalls, and after flushing the fuel system and on normal fuel it starts up as if nothing had happened. Also, with a bad start, faulty sensors are connected. Especially the one that is responsible for the position of the crankshaft. If the DCD is defective, the motor will be unstable, and if it is possible to start the engine, it will immediately die out. Do not exclude its breakdown.

Conclusion

If you do not start a car "Ford Focus 2", do not worry much. Often in this situation with the engine and the car is all right. Just some elements are out of order and require replacement. Sometimes it's enough to change the gasoline to a better one, and the car will start at the first time.
