how to check hyundai fuel pump accent
Determine what is on a Hyundai Accent car ( Hyundai Accent), the engine does not start due to a malfunction fuel pump(gasoline pump), quite simply. Indeed, after turning the ignition key to the IGN position (ignition on), the driver should hear the noise of the fuel pump motor running for a couple of seconds, which should raise the pressure in fuel rail and then disconnect. If this sound is not there, you will have to find out where the malfunction is in this electrical circuit, which they usually start looking for by checking the status of the fuel pump relay.
This relay is located in the mounting block under the hood of the car. When the driver opens the cover of this unit, standing on the left side front wheel car, then fuel relay pump blue color will stand in the mounting block in the middle of the leftmost row. You can check this relay by replacing it with a similar relay, which must be known to be good. If gasoline pump and in this case will not work, then it will be necessary to find out what condition its electric motor is in.
To do this, it is necessary to apply voltage to its terminals directly from battery. For this we shoot backseat and a hatch cover to get to the fuel pump block, disconnecting which we will see five terminals. The top three terminals are for the fuel level sensor, and the bottom two terminals (plus and minus) are for the fuel pump.

If, as a result of this check, the fuel pump starts to work, then everything is in order with it. For further troubleshooting, you will need a tester to check whether voltage is applied to the contacts of the fuel pump block connector. In the absence of a voltage of 12 volts, you will have to ring the wires from this connector to the mounting block. Sometimes the main relay becomes the culprit for the lack of voltage, through which voltage is applied to the relay winding fuel pump. It is located in the relay box located to the left of the steering column behind a small glove box. Installed on the sidewall of the body, extreme left.
Quite often, the cause of the fuel pump motor failure to turn on is an alarm that blocks the supply of voltage to its terminals. This can happen either due to the failure of the alarm relay, or due to poor-quality twisting of wires during its installation.

and how to distinguish signaling glitches from a malfunction of the fuel pump power line. The pump works directly from the battery. filter mesh new clean. I remove the connection block with the fuel module under the seat, while a buzzing appears under the hood on the sensor next to the throttle position sensor
Most likely the XX sensor is buzzing. If the pump is running on battery power, but not in normal mode, you need to look for a break. Maybe an alarm. To be honest, I see no reason to turn off the fuel pump alarm. The punks and the sound of the siren will scare away, but the break in the power line of the fuel pump will not stop the professional.
I have a similar situation. just the car stalled while driving. Why doesn't the immobilizer light always come on? After that, the car started up a couple of times and stalled again. tell me the reason
It will be required when the car's engine starts to lose power for no reason, and the fuel system makes noise during operation. given signs indicate a malfunction of the fuel system, and the most likely cause of the malfunction is a breakdown of the fuel pump. Replacing the fuel pump on the Accent can be done on its own - consider the order in which the system should be disassembled and a new pump installed.

If the gasoline pump does not work on the Hyundai Accent, the car simply stops moving and you lose the opportunity to move around on it and quickly solve your own business. Breakage so important mechanism- it's always a big problem which requires an immediate solution. We will analyze why the Accent gas pump does not work and how to check the device.
The gasoline pump does not work on the Hyundai Accent - reasons
Modern a car has a complex structure and consists of many units. It is possible to establish that it was the fuel pump that caused the idle car by the following signs:
- The car does not start moving, but at the same time the candles are in order, the spark is normal, the engine is running, and there are no flashes in the cylinders.
- There are separate flashes in the cylinders, but the engine does not start.
- There are "floating" turns.
- The motor is running idling stable, however, with increasing speed or when the car starts to move, power unit stops.
- There are car twitches, engine failures, the car stops pulling.
- The fuel pump on the Hyundai Accent does not pump.
- The fuel pump on the Hyundai Accent makes a loud noise
The last - loud noise - usually indicates that the pump will soon have to be changed. The original one is quite expensive, so you can choose an alternative - a gas pump from the VAZ 2110 is suitable for the Accent, which is several times cheaper.
How to replace the fuel pump, read the article "Hyundai Accent Fuel Pump Replacement". We also recommend watching a video on this topic.
The symptoms listed above are not always the result of a pump failure. Some of them can occur, for example, when the filter is very dirty. fine cleaning, in case of failure of the air flow sensor or as a result of clogging of the nozzles. When the Hyundai Accent fuel pump does not work, it does not buzz and does not turn on.
How to check the fuel pump on a Hyundai Accent
Usually, when the fuel pump is running, a characteristic noise is heard - the sound of the pump engine running. It does not last long, just a couple of seconds after starting the engine. The absence of sound is clear sign the fact that there is no power to the gas pump Hyundai Accent TagAZ. If so, the pump will need to be checked. Let's figure out how to check the gas pump on the Accent yourself.
Checking the fuel pump relay
When there is a problem with the fuel pump, the first thing to check is its relay. It is located in the mounting block, which can be found under the hood. When viewed from the side of the front left wheel, the fuel pump relay on the Accent is located in the middle of the leftmost row, it is light blue in color. To check the chain and performance of this relay, you just need to replace it with a similar one and try to start the pump. If the device is stable, the problem is definitely in the relay. If not, you need to look for the problem further. The next step is to check the pump motor.
Checking the electric motor
To check the fuel pump engine, you need to give voltage to the terminals directly from the battery. This is done as follows:
- Remove the rear seat cushion.
- Remove the fuel pump manhole cover.
- Disconnect the pump block, 5 terminals go to it (the top 3 go to the fuel level sensor, the bottom 2 lead to the pump).
In the event that, after the actions taken, the pump starts to work, it means that the device is working properly. If not, you will have to look for the cause of the breakdown further.
We use the tester
You should continue checking using a special device that will help determine if voltage is going to the contacts of the block connector. The nominal voltage value is 12 V. If the fixed level does not match, you need to ring the wires from the connector to the mounting block and check the wiring to the fuel pump.
Sometimes, if the fuel pump does not work and the Accent immobilizer is on, the alarm installed on the car can block the start of the fuel pump engine. It prevents the transmission of voltage to the terminals. In this case, the alarm relay is faulty or the alarm itself is set incorrectly.
When is it necessary to turn off the pump?
There are cases when motorists remove the Accent fuel pump power deliberately. So, many advise turning off the fuel pump when working on gas. This will keep operational properties fuel pump and prolong its life.
Now you know how to check the gas pump on the Accent and what to do if the gas pump does not work on the Hyundai Accent.
