In a vehicle's fuel supply system, the gas pump plays the role of transporting fuel from the fuel tank to the power unit.
The fuel pump begins its work immediately after turning on the ignition, as soon as electric current flows to its terminals.
Despite the fact that the element is designed for a long service life, it happens that at the most inopportune moment it fails. Among the reasons for this are the following:
- poor fuel quality;
- accumulation of garbage in the system;
- breakdown of fuel pump elements.
Which fuel pump is suitable for Ford Focus 2?
The original spare part is quite expensive, so, as an alternative, you can purchase a fuel pump, which is supplied to our country by the Italian company ERA. Note that the company does not produce auto components, but only packages and sells them as its own brand. Therefore, the fuel pump for Ford Focus 2, which the Italians offer, is an original spare part, but for some reason it costs less.
Fuel pumps similar to Ford's are found on Volvo S40 and Mazda-3 cars, although they are somewhat more expensive.

A malfunction in the fuel supply system can be determined by the following symptoms:
- the power unit does not start;
- while driving, jerking often occurs, as if the engine does not have enough power, its speed drops;
- When the power unit operates at idle speed, all sorts of noises can be clearly distinguished in the area where the gas tank is located.
However, if the described symptoms appear, you should not rush headlong, abandoning everything, and run to the auto store for a new fuel pump. First, it’s worth diagnosing it and making sure that it is the source of the problems described.
Diagnostics of the operation of a part consists of checking the pressure it creates. Immediately after turning on the ignition, the fuel pump starts working. Therefore, if it is working properly and voltage is supplied to its terminals, a clearly audible sound of its operation should be heard.
It is worth noting that if there is pressure in the fuel system, the gasoline supply pump will not turn on. To put it simply, when you turn the ignition back on, the system is already under pressure and the sound of the fuel pump running will not be heard.
If you suspect a breakdown of the electric fuel pump, the first step is to check its fuse and relay.
The pressure is checked using a pressure gauge connected to the fuel rail circuit. When you press the accelerator, the device should respond to this by changing the readings. The opposite indicates a faulty fuel pump.

At the ignition switch we take the power wires. 12 Volts - red Ignition - green/yellow Starter - gray/red ACC - yellow
to the dimensions on the light switch to the orange/black (in some to orange/yellow) wire (positive polarity)
The fuel pump can be found in the right threshold - green/orange.
Stop - green/white on the “frog” brake pedal.
The central locking control and door limit switches are located on the fuse block at the bottom of the passenger's feet. (In some cars, the central lock is located in the driver's door - green/h and sin/h). Central locking (controlled by minus) - black/orange and black/green in an orange connector. When you search, close all the doors, otherwise the locks will not close. Door switches (positive) - b/w (driver's), b/or (rear left), b/w (rear right) and c/sin (front right) in the same orange connector as the cz. Look with a voltmeter, not a probe. The tester will not show “plus” when the door is opened (at least with a light bulb). The trunk limit switch is in the same place as all the others and is also positive - black/cr.
If there is a hood switch on the car, then you can take it in the adjacent blue connector - h/w. By the way, he is also positive.
To control the engine, it is better to take a signal from an injector (any). Right wire in the direction of travel. You can try charging - the pink wire on the generator. But it takes a long time for 12 volts to appear on this wire. Therefore, autorun often does not work correctly. In terms of noise (or voltage), it works, but when the stove is fully turned on (motor at maximum), it again does not work correctly (in the case of Sherkhans, it does not work 100% correctly).
If the low beam is turned on when you turn on the ignition, then (to prevent this from happening) cut the thin side and the thin side on the headlight switch.
Fuel pump motor
This element is the main power unit of the gasoline supply pump. It is located inside the fuel pump and is intended to build up pressure in the fuel supply system.
If it fails, the operation of the entire system is paralyzed. The original part is quite expensive, so, as an alternative, you can use an electric fuel pump motor from a VAZ-2110 car, which is fully suitable for use in the Ford Focus 2.

The popularity of Ford Focus cars in Russia is associated with their reliability, affordability and ease of maintenance. However, individual components and parts have a limited service life, after which they require replacement. The fuel pump is the main element of the fuel system, and its timely replacement will allow the car owner to avoid more serious troubles.
Ford Focus fuel pump: manufacturers, location and reasons for failure
The fuel pump is the main component of the fuel supply system. Almost any malfunction leads to the engine stopping.
The first generations of Focus cars were equipped with standard fuel pumps. Since 2007, the manufacturer began to equip machines with devices with an emergency shutdown function. This function is activated at the moment of an accident and completely stops the supply of fuel to the system.
Manufacturers
New Ford Focus vehicles are equipped with Visteon fuel pumps. This is an American corporation that produces and supplies components for almost the entire family of Ford cars. Now Visteon representative offices also operate in Russia, so Focus car owners will always be able to purchase the necessary spare parts in the original version.
The body of the original fuel pump must have a yellow sticker from the manufacturer
For non-original components, it is recommended to buy fuel pumps manufactured by Mesmer and Era. They are quite reliable and cost much less than Visteon.
Location
Getting to the fuel pump in a Ford Focus is quite difficult. The manufacturer did not assume that Russian car owners would change it themselves, and installed a pump in the gas tank.
On a Ford Focus, the fuel pump is submerged in the gas tank.
Symptoms of malfunctions
You will most likely need to replace the fuel pump if:
- when you press the accelerator pedal, the engine starts to run jerkily;
- at idle speed the engine is unstable, with “dips”;
- the car does not start the first time;
- fuel consumption is significantly higher than usual.
A failed element cannot be restored, so you should not try to repair it.
Replacing the fuel pump on a Ford Focus car
Removing the gas tank and dismantling the pump are quite labor-intensive procedures. However, Russian craftsmen have figured out how to get to the necessary elements without removing the gas tank.
Precautionary measures
When replacing the fuel pump, fuel may leak and splash. Therefore, all work should be performed outdoors. If you decide to do work in the garage, then it must be completely ventilated. For protection, use rubber gloves and a respirator.
Procedure for replacing the pump
Before starting work, make sure the vehicle is stationary. Engage first gear and raise the parking brake handle.
In addition to the new pump, you will need the following tools and supplies:
- metal scissors;
- set of wrenches;
- flat screwdriver;
- old cloth or rags.
Follow the steps in the following order:
- Install a new fuel pump with a new seal in its place.
Carefully remove the pump from the gas tank
- When dismantling, the pump will not be able to pass through the hatch, so the size of the hole must be increased. To do this, use scissors to cut a circle with a diameter of about 25 cm on a metal panel. To avoid cutting yourself, bend the edges of the widened hole.
The fuel pump hatch is located under the rear seats of the car
- Open the rear doors and remove the rear seat cushions from the interior.
- Under the mat, find a metal panel - under it is the fuel pump hatch.
When dismantling, use metal scissors to enlarge the hole in which the fuel pump is installed.
- Disconnect all fuel lines from the pump. Be careful as gasoline may leak from the pipes. It is better to cover the entire surface of the panel with rags in advance.
- To reduce the pressure in the fuel supply system, start the engine - it will run for a few minutes and then stall.
- Use a flathead screwdriver to pry up the O-ring and carefully pull the pump out of the tank.
Install a new pump in place of the old one
- Connect the fuel lines.
Useful tips
Perform the work extremely carefully so as not to damage the fuel lines. Do not point gasoline pipes at your face—the fuel is under high pressure.
If you have never worked with metal scissors, first make several holes around the circumference with a thin drill. This will make the cutting process much easier. When doing this, try not to touch the plastic housing of the gas tank.
After installing the new pump, you must somehow close the cut hole. Some car owners simply seal it with masking tape, others cut out a cover from sheet metal and attach it to the surface. Then the carpet and rear seat cushions are returned to their place.

Replacing other elements of the fuel system
Fuel system components that should be replaced periodically include the screen, filters, and relays.
Net
The fuel pump strainer is the first fuel filter. It is on this that dirt accumulates and enters the tank along with low-quality gasoline. Therefore, the mesh sometimes has to be cleaned or replaced.
Replacing the mesh is not particularly difficult:
- Wipe the removed fuel pump dry with a rag or cloth - there should be no drops of gasoline on it.
- Bend the clips on the top of the pump and remove the screen.
- Install the new mesh and secure it with clamps.
Old (left) and new (right) fuel pump screens
If there is no mechanical damage on the surface of the old mesh, it can be cleaned under high pressure.
In this simple way, you can return the fuel pump to functionality.
Filter
The manufacturer recommends changing the fuel filter on a Ford Focus every 30 thousand kilometers. However, taking into account the quality of domestic roads, this figure drops to 20–25 thousand km.
The fuel filter cleans gasoline from dirt
The fuel filter in all Ford Focus cars is located in the gas tank, under the rear seats. The procedure for replacing it is as follows:
- Drive the car onto a viewing hole or overpass.
- Remove the element responsible for the operation of the fuel pump (blue) from the fuse box.
- Start the engine and wait until it uses up all the fuel and stalls.
- Make sure there is no gasoline left in the system by starting the engine again.
- The fuel filter is located in a niche to the right of the gas tank.
The fuel filter is located at the bottom right of the gas tank
- Disconnect the connector from the filter. At the same time, do not touch the green wire - it ensures the return of fuel to the system.
- Carefully disconnect the fuel pipes - there may be gasoline remaining in them.
When replacing the fuel filter, the tubes are disconnected on both sides
- Using a size 8 wrench, unscrew the filter mounting bolt.
- Remove the filter along with the mount.
- Using a 7mm wrench, disconnect it from the bracket and install a new filter in this place.
- Attach the filter together with the mount to the car body.
- Connect all fuel pipes, thoroughly cleaning them from dust and dirt before doing so. When the connectors are connected correctly, you will hear a slight click.
- Replace the fuse.
Relay
The cause of the fuel pump stopping may also be a blown fuse or a failed relay. This can be easily resolved by replacing faulty elements with new ones.
The fuel pump fuse is blue
The relay and fuse box is located to the left of the engine behind the shock absorber dome. The fuel pump fuse is blue, the relay is black.
The relay responsible for supplying power to the fuel pump is black.
When replacing, the faulty fuse or relay is removed from the socket using pliers, and a new one is installed in its place.
Replacing the fuel pump of a Ford Focus car yourself is complicated by its extremely inconvenient location. However, if there is desire and free time, any car owner can do this work. In this case, you just need to carefully follow the suggested recommendations.

Fuel pump relay. Where is it located?
It is impossible not to mention this important element in the article. The relay is intended to turn the fuel pump on and off, that is, the electric pump operates and creates pressure in the system, as a result of which gasoline flows through the line into the power unit. As soon as the pressure reaches the maximum level, the relay turns off the power supply to the fuel pump, and, conversely, as soon as the pressure decreases, it turns it on.
The relay is located under the dashboard. To test its performance, just turn on the ignition. If the relay is working properly, it should make a clearly audible click, indicating the start of its operation.
What if the fuel pump doesn't work?
Let us repeat that the fuel supply pump does not like counterfeit gasoline and does not forgive the driver’s negligence. Dismantling of old electric fuel pumps showed that most of the units failed due to clogging of the fine filter, which causes overheating of the device, followed by breakdown of the fuel pump. In such a situation, only repair or replacement of this element will allow the normal operation of the car to continue.
By the way, it is unlikely that you will be able to disassemble and repair the pump yourself without certain skills and understanding of how it works. Therefore, in order not to overpay again, you should take the faulty device to a specialized repair shop.
Replacing the fuel pump for Ford Focus 2
How to properly remove the fuel pump? Let us describe the step-by-step sequence of actions:
- It is necessary to de-energize the vehicle's electrical circuit by disconnecting the battery.
- In the luggage compartment, you need to unscrew the fastening bolts from the protective cover and remove it. The fuel pump, which is located on top of the gas tank, next to the sensor, will appear in the access field.
- We release the pressure. To do this, remove the fuel hoses from the pump, having previously placed marks on them, and disconnect the sensor wire. Next, we start the engine and wait until it stalls, after which you need to crank the starter again to make sure there is no pressure in the system.
- Remove the fuel pump, being careful not to damage the o-ring.
- We replace a non-working device.

Price of a fuel pump for Ford Focus 2
Before we announce how much the original Focus costs, we note that recently the points of sale of auto parts are filled with cheap original components made in Poland and the Czech Republic. Everything would be fine, but there are no such production facilities on the territory of these countries. Consequently, ordinary Chinese counterfeits are sold under the guise of original Ford spare parts. It is worth remembering that original car parts are always covered by the seller’s warranty.
So, the average price of an original fuel pump for a Ford Focus 2 today is about $130, and its analogue, produced by BOSCH, will cost about $70.
Impressive! Therefore, it is very important to monitor the condition of this part, promptly identify and eliminate its minor faults, so as not to shell out such a large sum for its purchase in the future.
