What You'll Learn
Fuel pump relay location
The fuel pump relay in a 2005 Nissan Altima is typically located in the under-hood fuse box. The fuse box is located on the passenger side of the engine, in the black box near the washer bottle fill spout.
The fuel pump relay is part of a control unit known as the IPDM. The IPDM can be opened by removing its cover, which will reveal the location of the fuel pump fuse. The relay is integrated within the fuse.
Symptoms of a faulty relay include engine cranking without starting or intermittent stalling. To troubleshoot, you can first check the relay by swapping it with a similar one in the fuse box. If the relay is defective, replace it with an OEM part.
It is important to note that the entire fuel pump assembly should be replaced, not just the pump. There are two locking mechanisms under the front seat that need to be pulled to the front of the car to free the seat from the door. Removing the bottom seat cushion will then provide access to the cover plate of the fuel pump.
Fuel pump relays for the Nissan Altima can be purchased from Advance Auto Parts, with prices ranging from $11.79 to $887.99.

Fuel pump relay failure symptoms
The fuel pump is an essential part of your car, responsible for delivering fuel from the tank to the engine. A failing fuel pump can cause issues with combustion and engine performance and, in some cases, even leave you stranded.
Symptoms of a faulty fuel pump relay in a 2005 Nissan Altima can include engine cranking without starting, intermittent stalling, or a complete failure to start. The fuel pump relay in a 2005 Nissan Altima is typically located in the under-hood fuse box, specifically in the IPDM, which is a control unit located under the hood on the passenger side of the engine.
To troubleshoot a potential fuel pump relay issue, you can first try swapping the relay with a similar one in the fuse box and checking for any improvement in symptoms. You can also inspect the related fuses for continuity and ensure that wiring connections are free from corrosion.
Other signs of a failing fuel pump in your Nissan Altima include sputtering under load, power loss, or a high-pitched whine from the rear of the vehicle. To diagnose a potential fuel pump issue, you can listen for the pump prime when you first turn the ignition key to the "ON" position without starting the engine. The fuel pump should run for approximately 2-3 seconds to build initial system pressure. You can also perform a fuel pressure test by using a specialized pressure gauge that taps into the fuel system to measure pressure while cycling the key.
If you suspect a fuel pump relay failure, it is important to consult a professional mechanic or a certified repair shop for proper diagnosis and repair. They can perform a comprehensive inspection of the fuel pump and related components, including the fuel filter, wiring, connector, and fuel pressure regulator.

Fuel pump relay replacement cost
The fuel pump relay for a 2005 Nissan Altima can be purchased from Advance Auto Parts, with prices ranging from $11.79 to $887.99. The cost of labor for a fuel pump relay replacement is estimated to be between $41 and $61, while the parts are typically priced at around $43. This range does not include taxes and fees and may not be applicable to your unique location.
It is important to note that diagnosing a relay is a simple process with testing. On the exterior of most relays, there is a diagram of the switches inside. A fuel pump relay will have a maximum of two switches, but normally only one. By applying power and ground to the small circuit with proper polarity, the relay should click. The secondary test involves measuring the resistance across the relay and comparing that data to the service manual or the relay itself.
If the relay is proven to be in good condition but still malfunctions, the terminals can be tested in the junction block with a test light or multimeter. A multimeter is preferred for its accuracy, but a test light will indicate whether power is present or not. The ignition switch may also be a factor, as it can provide either a switched ground or a switched hot (battery voltage) to the fuel pump relay. This information is crucial when testing the relay and the power distribution block.
In the case of a switched ground, there will only be continuity between the battery negative cable and the relay when the key is in the 'run' position or when the fuel pump primes. Replacing the fuel pump relay in a 2005 Nissan Altima involves accessing the pump, which is located beneath the back window. To do this, remove the bottom seat cushion to access the cover plate of the fuel pump, which is on the driver's side. There are four 1/4 turn plastic phillip head locks on the cover. Remove these, raise the cover, and disconnect the electrical connection from the pump. Next, disconnect the fuel line, which will have residual pressure in the tank. Capture or remove any fuel that may spill out during this process.
The fuel pump is protected by a threaded black ring in the tank, which can be removed by turning it clockwise. After removing the ring, take the fuel pump halfway up, being mindful of the two wires attached to the bottom of the pump and the fuel gauge sending the float unit. Tilt the pump and maneuver it to clear the float and wiring. It is important to note that the fuel line is under pressure, and smoking is not allowed during this process. Additionally, care must be taken not to bend or distort the sending unit float arm.

Fuel pump relay troubleshooting
The fuel pump relay in a 2005 Nissan Altima is typically located in the under-hood fuse box. Symptoms of a faulty relay include engine cranking without starting or intermittent stalling. To troubleshoot, first check the relay by swapping it with a similar one in the fuse box. The fuses are positioned to the left of the centre, while the relays are on the right side, with the middle relay being the fuel pump relay.
You can also check the fuel pump fuse by using a test lamp or voltmeter to make sure it has power. The fuel pump relay is part of a control unit known as the IPDM, which is located under the hood on the passenger side of the engine.
If the relay is defective, replace it with an OEM part. You can find aftermarket or OEM fuel pump parts for the Nissan Altima ranging from $11.79 to $887.99.
- Remove the bottom seat cushion to access the cover plate of the fuel pump. The plate is flat and on the driver's side.
- Remove the four 1/4 turn plastic phillip head locks on the cover.
- Raise the cover and disconnect the electrical connection from the pump.
- Disconnect the fuel line, which will have residual pressure in the tank.
- Squeeze the connector lock and pull the fuel line to the front of the car with a twisting motion.
- Place something under the vehicle or fuel line to capture or remove the fuel.
- Remove the threaded black ring in the tank by turning it clockwise.
- Take the fuel pump halfway up.
- Tilt the pump and manoeuvre it until you clear the float and wiring.
Note: The fuel line is under pressure, and there is a risk of fuel spillage, so caution is advised.
