Ford Focus 2 cars will function properly only if fuel is constantly supplied to the power plant. The fuel pump is responsible for this. "Ford Focus 2" is equipped with it without fail. If the pump does not work correctly, this may cause the inability to start the engine.
Element device
These vehicles have a submersible electric rotary pump. It is equipped with coarse and fine fuel filters. The device is equipped with a fuel pressure regulator. The mechanism is installed directly in the tank. This reduces the risk of steam jams.
Gasoline is supplied under pressure, and not as a result of rarefaction. The original gasoline pump (including Ford Focus 2) is produced in the United States. If replacement is necessary, it is ideal. As for the cost of the device, the price of the original is about three to five thousand rubles. Similar pumps from other manufacturers are sold for one to two thousand rubles. There are frequent cases when car owners purchase and install BOSH elements, which are also suitable for the VAZ-2110. They are inexpensive and have high performance features.
Common problems
A fuel pump (Ford Focus 2nd generation) can fail for various reasons. A characteristic symptom of a malfunction is a hum during the operation of the pump. Even new products can buzz. If the buzzes are especially loud, then this indicates that the mechanism has burned out. If the Ford Focus 2 petrol pump does not start, this indicates that it does not pump fuel. The engine, accordingly, cannot work even at idle. Often on these cars, the elements fail due to the operating life - on average, one original device can work for 5-7 years.
However, this figure is directly related to the quality of gasoline used to fuel the car. Sometimes even the fuel pump grid does not save from a breakdown. Ford Focus 2 refuses to start. If rust and various impurities get inside the system, this can cause damage to the mechanism. Also among the reasons - mechanical damage to important elements of the device. The pump also fails due to a violation of its tightness.
Symptoms
If the engine does not work smoothly at set speed, but jerks occur - this directly or indirectly indicates a malfunction with the gas pump. This happens when pipes are clogged in the fuel system. Normal circulation of fuel through the system is simply impossible. Another sign that indicates a malfunction is a loud noise, which is especially heard at idle in the rear of the car.
If the motor is unstable at idle, this indicates problems with the device. Also, if the pump breaks, the engine speed can float. Another sign is the difficulty in starting the engine, regardless of whether it is hot or cold. And finally, fuel consumption may increase or decrease. If at least one symptom is observed, this indicates the need to replace the pump. It should be noted that the disassembly and repair of
fuel cells at the "Focus" is not performed. The element changes entirely. You can buy the original. But it’s easier and cheaper to get a good analogue. There are two replacement options. One provides for the dismantling of the fuel tank, the second without removal. In the case of the first method will have to work, the replacement process is very time-consuming. The second option is more acceptable if the work is done by yourself.
How to check the gas pump?
Before pronouncing a death sentence on a device, experts recommend checking it. Testing or diagnostics will include a power check as well as pressure. The first step is to pay attention to the fuel pump fuse. “Ford Focus 2” is equipped with such in any configuration. It is located in close proximity to the control unit.
If the component is defective, it should be replaced. Perhaps this will bring the device back to life. Next, they diagnose the relay, which is hidden under the dashboard. You need to remove the protective cover from the device and then turn on the ignition. If everything is fine with the relay, then the driver will hear a distinctive click-like sound. If nothing happens after switching on the ignition, the pump is broken. The pressure level is checked using a pressure gauge that is pre-connected to the fuel rail. If at the moment of pressing the accelerator pedal the measuring device does not react in any way, the car needs to replace the fuel pump.
Dismantling hatch
Engineers in the development of this car did not take into account that gas pumps are not eternal. If you consider where the fuel pump is located (including Ford Focus 2 2.0), then the hatch under the rear seat would be very useful - this greatly simplifies dismantling.
And since the pump is installed directly in the tank, it is necessary to remove the element itself to replace it. This procedure can take a lot of time, and it is completely impossible to carry out a replacement 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 carried out on the overpass or in the pit in the garage. Specialists recommend the use of protective gloves for this work. It is also important that the garage is well ventilated - a large amount of gasoline vapor will be released during operation.
First of all, remove the thermal protection and the filter tube. Next, through the luggage compartment, unscrew the bolts to access the tank hatch. Then disconnect the hoses going to the pump, as well as the terminals from the sensor. If the removal of the Ford Focus 2 fuel pump is carried out independently for the first time, experts recommend numbering all the hoses and wires. After that, they twist the starter and start the car engine. The engine must run until it dies and the fuel system is completely empty. Next, the pump is removed from the tank, it is worth paying attention to the o-ring. You need to be careful with him. O-ring is very fragile. When removing the pump, it is recommended that all hoses and other system components be checked for integrity. If a crack is detected on the element, then the damaged part must be replaced. Then pull out the fuel pump. Ford Focus 2 continues to be on the overpass. The element is laid on prepared rags, paper or cardboard.
Pump replacement
Installing a new device is performed in the reverse order. At the last stage, the starter is turned a little so that a certain amount of fuel gets into the fuel system. At the same time, the presence of leaks or other defects is checked.
Car repair and maintenance experts recommend checking how the car works after
replacing the gas pump. It is best to ride in several modes. For example, it is worth driving along the highway at high speed.
Is it possible to repair fuel pumps "Ford Focus 2"
Not always a dead pump is broken completely. Sometimes only one of the components is faulty. To determine what failed, you will need diagnostics. From time to time, the assembly parts must be flushed and the filter replaced. It is also worth considering that it is quite difficult to disassemble a Ford Focus 2 fuel pump. Repairs are only available to qualified personnel.
