How to check the fuel pump relay yourself

The fuel pump relay is a device that provides and stops power supply to the fuel pump upon command from the ECU. The device is fully responsible for controlling the fuel pump, and also performs certain additional functions, which depend on the specific brand and equipment of the car. For example, on cars with automatic transmission, if it is necessary to activate the kick-down mode (intensive acceleration), the specified relay is activated.

Where is the fuel pump relay located?

To answer the question of where the fuel pump relay is located, you need to know exactly the make and model of the car. The installation location on different cars is the area near the injection control unit; the solution can be installed under the dashboard near the fuse box, etc.

Often, if they need to make their own repairs, car enthusiasts are interested in where the fuel pump relay for the VAZ 2110 injector is located. On this model, the fuel pump relay is located near the passenger's left foot under the dashboard. It should be added that the fuel pump fuse is also installed nearby.

Signs and Symptoms of a Bad Fuel Pump Relay

Let's start with the fact that the fuel pump is controlled through a relay according to the following general scheme:

• the driver inserts the key into the lock and turns on the ignition;
• after turning on the ignition, the relay turns on the fuel pump for 2-3 seconds, which is necessary to create pressure in the fuel rail.
• then you can hear a characteristic sound as the fuel pump relay clicks, which has turned off the fuel pump;
• subsequent operation of the fuel pump will be possible under 2 conditions: rotation of the engine by the starter during startup and further independent operation of the already running engine.
• after turning off the ignition and stopping the engine, the relay turns off the fuel pump immediately or after 1 second.

Also on some cars the device serves as a kind of engine speed limiter. If the engine speed approaches maximum and begins to exceed the permissible threshold, the fuel pump is switched off via a relay. The gasoline supply stops, the speed decreases, after which the element supplies power to the pump again.

It should be additionally noted that on some vehicle models the fuel pump does not turn on after turning the key in the ignition, but at the moment the driver's door is opened. This solution allows you to quickly start the engine, as it ensures that the necessary operating pressure is created in the fuel system in advance. In other words, the pump pumps gasoline until the driver decides to insert the key and start the engine.

If the relay malfunctions, then power may not be supplied to the fuel pump. The second option is that the pump hums or hums constantly, that is, it does not turn off a few seconds after the required pressure is created in the fuel line. In the first case, the engine often cannot be started because the pump does not pump and there is no gasoline in the fuel rail.

In the second case, the fuel pump relay gets stuck (the fuel pump relay does not work) and the battery charge is consumed for the constant rotation of the fuel pump motor. Let us add that on some cars, starting the engine is possible even if there are certain malfunctions in the operation of the element, since the pump relay connection diagram allows the device to operate while the starter is cranking.

Checking the fuel pump relay yourself

At the beginning of the test, you need to get to the following elements: the pump fuse and its relay. Having decided which relay is responsible for the fuel pump, you should also inspect the fuse. Additionally, you need to check the fuse because the fuel pump relay heats up and then does not respond in a timely manner or does not operate at all due to a malfunction of the specified fuse.

The easiest way to check is to install a known working device. Also in the list of general ways to check a fuel pump relay with your own hands, you can highlight one when a test lamp is connected instead of a relay. After turning on the ignition, the light should light up. You can also place a jumper on the terminals during diagnostics. If after turning the ignition key the fuel pump starts to work, then this indicates a malfunction in the fuel pump control device.

Now let's look at another available way to check using the example of a VAZ 2110 car. The fuel pump relay itself in this model is located near the fuse.

1. To check, you will need a multimeter or a test light of no more than 0.25 A. Next, you should alternately measure the voltage at the control terminals of the device, simultaneously fixing the contact to ground. This method allows you to accurately determine whether the fuel pump relay needs to be replaced.
2. If the warning light does not light up, the pump fuse is working or replaced with a known working one, then attention should be paid to the wiring from the relay to the computer. At the same time, the possibility of malfunctions in the engine control unit should not be ruled out.

Finally, we add that the element may also refuse to work or stick after failures or unqualified installation of a car alarm/immobilizer. The fact is that security and anti-theft systems with an engine start blocking function are often based on interrupting the power supply to the fuel pump. In this case, these systems must be diagnosed separately.

The price of the original mounting block for the Nissan Primera P12 assembly starts from 3,500 rubles, analogues from 3,000 rubles. Relays - switches priced from 550 rubles.

Signs of faulty fuses on a third generation Nissan Primera

• An indicator on the dashboard indicates a breakdown of mechanisms and equipment in the engine compartment;
• Power units do not operate when current is supplied or modes are activated;
• The fuse box is hot to the touch, with a clearly uncharacteristic temperature;
• The smell of melted plastic can be heard at the location of the protective modules.

Causes of fuse failure

• Violation of the terms of technical inspection of the vehicle, as a result of which the equipment ceases to function properly;
• Purchase and subsequent installation of non-original spare parts;
• Violation of the technology for installing spare parts and components;
• Damage to the mounting block with protective modules;
• Short circuit in electrical wiring;
• Damage to cable insulation;
• Oxidation of contacts, condensation, moisture ingress into the protective housing;
• Loose terminal contacts.

Replacing fuses on Nissan Primera P12

Preparatory stage:

• Flat head screwdriver;
• Additional lighting;
• A set of new relays - switches, fuses;
• Tweezers for removing melting elements.

Sequence of actions when replacing modules in the cabin:

• We place the car within the perimeter of the repair area, block the rear row of wheels with wheel chocks, and squeeze the parking brake;
• Left-hand drive: open the driver's door, a mounting block is installed to the left of the steering column, remove the cover;
• Using the serial number indicated on the back of the cover, we find the module. Using tweezers, remove it from its original place and replace it with a new one.

To replace the entire mounting block, you must additionally unscrew the two mounting screws that secure the board to the torpedo body.

Replacing fuses in the engine compartment of a third generation Nissan Primera (P12):

• Turn off the ignition, squeeze the parking brake on the Nissan Primera P12, open the hood;
• On the left behind the battery there is a black plastic case; we snap off the cover;
• By serial number we find the fuse, relay - switch. We remove it, replace it with a new one as necessary, and carry out preventive maintenance.

Fuse Maintenance Recommendations

Nissan Primera P12

• After driving through puddles or in the rain, check the mounting block for moisture. Dry, blow with a stream of compressed air as necessary;
• Buy spare parts and consumables mainly from certified points of sale, official representative offices, dealer centers;
• Check the functionality of the fuses with special equipment - a multimeter.
