Cars "Ford Focus 2" will function correctly only if the fuel is constantly supplied to the power plant. The fuel pump is responsible for this. "Ford Focus 2" is equipped with them without fail. If the pump does not work properly, this can cause the engine to not start.
Element Assembly
These vehicles are equipped with a submersible electric rotary pump. It is equipped with filters for coarse and fine cleaning of fuel. The device is equipped with a fuel pressure regulator. The mechanism is installed directly in the tank. This reduces the risk of the formation of steam jams. Gasoline is supplied under pressure, and not as a result of dilution. The original petrol pump (Ford Focus 2, including) is manufactured in the USA. If it is necessary to replace it, it is ideal. As for the cost of the device, the original price is about three to five thousand rubles. Similar pumps from other manufacturers are sold for one or two thousand rubles. It is not uncommon for car owners to purchase and install "BOSCH" elements, which also fit the VAZ-2110. They are inexpensive and have high performance characteristics.
Common Problems
The fuel pump ("Ford Focus" 2nd generation) can fail for various reasons. A characteristic sign of a malfunction is the hum when the pump is running. Even new products can buzz. If the buzz is especially loud, then this indicates that the mechanism is burnt out. If the Ford Focus 2 petrol pump does not start, this indicates that it does not pump fuel. The engine, accordingly, can not work even at idle. Often on these cars, the elements fail because of their service life - on average one original device can work for 5-7 years. However, this figure is directly related to the quality of gasoline that is fueled by the car. Sometimes even a grid of the fuel pump does not save from breakage. Ford Focus 2 refuses to start. If rust and various impurities get into the system, this can damage the mechanism. Also among the reasons - mechanical damages of important elements of the device. The pump breaks down and due to a violation of its tightness.
Symptoms of malfunctions
If the engine does not operate smoothly during speed dialing, but jerks occur - this indicates, directly or indirectly, a problem with the petrol pump. This happens when tubes are clogged in the fuel system. Normal circulation of fuel through the system is simply impossible. Another sign that indicates a malfunction is a strong noise, which is especially audible at idle speed in the rear of the car. If the engine is unstable at idle, this indicates problems with the device. Also, if the pump breaks, engine speed may melt. Another sign is that it is difficult to start the engine, whether hot or cold. Well, finally, fuel consumption may increase or decrease. If there is at least one sign, this indicates the need to replace the pump. It should be noted that disassembly and repair of fuel cells on the "Focus" is not carried out. The element changes entirely. You can buy the original. But it's easier and cheaper to get a good analog. There are two options for replacement. One provides for the dismantling of the fuel tank, the second - without removing. In the case of the first method it is necessary to work, the replacement process is very laborious. The second option is more acceptable if the work is done by oneself.
How to check the petrol pump?
Before you make a death sentence, experts recommend checking it. Testing or diagnostics will include checking the power supply as well as pressure. The first thing to note is the fuel pump fuse. "Ford Focus 2" is equipped with those in any configuration. It is located in the immediate vicinity of the control unit. If the component is defective, it should be replaced. Perhaps this will bring the device back to life. Next, the relay is diagnosed, which is hidden under the dashboard. It is necessary to remove the protective cover from the device and then turn on the ignition. If the relay is fine, then the driver will hear a characteristic sound, like a click. If nothing happens after the ignition is turned on, the pump is broken. The pressure level is checked using a pressure gauge that is pre-connected to the fuel rail. If the measuring device does not respond at the time the accelerator pedal is depressed, the car needs to be replaced by a fuel pump.
A hatch that simplifies dismantling
Engineers in the development of this car did not consider that gasoline pumps are not eternal. If you take into account where the fuel pump is located (Ford Focus 2 2.0 including), then the hatch under the rear seat would be very handy - it greatly simplifies the dismantling. And since the pump is installed directly in the tank, the element itself needs to be removed for replacement. This procedure can take a long time, and it is completely impossible to replace in the field. Many owners modify the car with their own hands - they make hatches for removing the pump.
How to remove the pump
The process of removing the tank and dismantling the pump is most conveniently performed on the overpass or on the pit in the garage. Specialists recommend to use protective gloves for this work. It is also important that the garage is well ventilated - in the process of work will be allocated a large amount of gasoline vapor. First of all, remove the heat shield and the filter tube. Further through the luggage compartment, unscrew the bolts to access the hatch of the tank. Then, disconnect the hoses coming to the pump, as well as the terminals from the sensor. If the removal of the fuel pump "Ford Focus 2" is carried out independently for the first time, experts recommend the numbering of all hoses and wires. After that, twist the starter and start the engine of the car. The motor should work until it stalls, and the fuel system is not completely empty. Next, the pump is removed from the tank, it is worth paying attention to the O-ring. You need to be more careful with him. O-ring is very brittle. During the removal of the pump, it is recommended that all hoses and other system components be checked for integrity. If a crack is found on the element, then the damaged part must be replaced. Then pull out the fuel pump. "Ford Focus 2" continues to be on the flyover. The element is laid on a prepared rag, paper or cardboard.
Pump replacement
Installation of the new device is carried out in the reverse order. At the last stage, the starter is twisted a little, so that a certain amount of fuel gets into the fuel system. At the same time, check for leaks or other defects. Car repair and maintenance specialists recommend to check how the car works after replacing the gasoline pump. It is best to travel in several modes. For example, it is worth to go on the highway at high speed.
Is it possible to repair Ford Focus 2 fuel pumps?
The dead pump is not always broken completely. Sometimes only one of the components is faulty. To determine what went wrong, you will need diagnostics. From time to time, the parts of the assembly must be washed and replaced with a filter. Also it is worth considering that dismantling the fuel pump "Ford Focus 2" is quite difficult. Repair is available only to qualified personnel.
