2013 Altima Fuel Pump: Symptoms, Replacement Cost, and the Best Fix

If your 2013 Nissan Altima is cranking but won't start, sputtering at highway speeds, or making a loud whining noise from the rear of the vehicle, the fuel pump is the most likely culprit. Replacing the fuel pump on a 2013 Altima typically costs between $500 and $1,200 when installed by a professional shop, depending on whether you choose an aftermarket or OEM part. If you handle the job yourself, you can bring that cost down to roughly $180 to $450 in parts alone. The good news is that the 2013 Altima has an access panel under the rear seat, which makes the replacement faster and less expensive than older models that require dropping the fuel tank. This guide covers everything you need to know: the warning signs, the real costs, the tools and steps for a DIY replacement, and how to choose the right part for your car.

What the 2013 Altima Fuel Pump Does and Why It Fails

The fuel pump on a 2013 Nissan Altima is an electric in-tank unit. It sits inside the fuel tank and delivers gasoline to the engine at a specific pressure range. For most Altima models, that pressure should be between 49 and 56 psi. The pump relies on the fuel itself for cooling and lubrication. When the fuel level drops too low, the pump is exposed to air and cannot dissipate heat effectively. Over time, that heat damages the internal motor.

Several factors shorten the life of a fuel pump on a 2013 Altima:

  1. Running the tank low on fuel. This is the number one cause of premature failure. The pump overheats when it is not fully submerged.
  2. Contaminated fuel. Dirt, rust, or water in the gasoline can clog the pump's inlet strainer and damage internal components.
  3. A clogged fuel filter. If the filter is not replaced on schedule, the pump has to push against higher resistance, which generates extra heat.
  4. Electrical issues. A failing relay, a blown fuse, or corroded wiring can cause the pump to receive inconsistent power and eventually stop working.
  5. Normal wear. Fuel pumps typically last between 100,000 and 150,000 miles. After that, the internal brushes, bearings, and seals wear out.

Knowing these causes helps you prevent a breakdown before it happens. The single most effective habit is to refill your tank once it hits the one-quarter mark.

Symptoms of a Failing Fuel Pump on a 2013 Altima

A failing fuel pump rarely dies without warning. Your Altima will give you clear signs. Recognizing them early can prevent a complete breakdown and save you from more expensive repairs.

Hard starting. If your Altima cranks longer than usual before firing up, or if it takes multiple attempts, the pump may not be building enough pressure. This is especially noticeable after the car has been sitting overnight.

Engine sputters at high speeds. If your Altima hesitates or jerks when you accelerate on the highway, the fuel pump may not be delivering enough fuel to keep up with demand.

Loss of power under stress. Climbing hills, carrying a heavy load, or running the air conditioning may cause noticeable power loss because the pump cannot maintain proper fuel pressure.

Engine stalling. If your Altima stalls while driving, particularly at low speeds or when stopping, the fuel pump could be failing intermittently.

Whining noise from the fuel tank. A healthy fuel pump makes a low hum when you turn the ignition to the ON position. A loud whining or buzzing sound from the rear of the car indicates internal wear.

Decreased fuel efficiency. If you notice you are filling up more often without changing your driving habits, a worn fuel pump could be forcing the engine to run inefficiently.

Check engine light. A failing fuel pump that delivers inconsistent pressure can trigger diagnostic trouble codes related to fuel system performance. Common codes include P0001, P0002, and P0003.

Before assuming the fuel pump is bad, check the fuel pump fuse and relay first. These are much cheaper to replace and can cause similar symptoms. You can also listen for the pump by turning the key to the ON position without starting the engine. You should hear a two-to-three-second hum from the rear of the car near the fuel tank. No sound at all strongly suggests an electrical issue or a dead pump.

How Much Does a 2013 Altima Fuel Pump Replacement Cost?

The total cost depends on several factors, including the quality of the part and where you have the work done. Here are realistic ranges for a 2013 Nissan Altima:

  1. Independent shop using an aftermarket pump: $500 to $700 total.
  2. Independent shop using an OEM Nissan pump: $700 to $900 total.
  3. Nissan dealership using a genuine OEM pump: $900 to $1,200 or more.
  4. You supply the parts and pay labor only: $200 to $500, depending on local labor rates.
  5. DIY replacement (parts only): $180 to $450 for most 2013 Altima models.

National average estimates for Nissan Altima fuel pump replacement fall between $1,131 and $1,299, with labor costing $104 to $153 and parts ranging from $1,026 to $1,146. However, those averages often reflect newer models with more complex fuel systems. For the 2013 model year, the job is more straightforward because of the access panel under the rear seat.

Several factors determine the final price:

Parts quality. Aftermarket fuel pump assemblies typically cost $100 to $350, while genuine Nissan OEM pumps range from $250 to $500. The OEM part number 17040-3TA0D fits 2013-2018 Altima models with both the 2.5L four-cylinder and 3.5L V6 engines. That part costs about $447.91 online, with an MSRP of $683.63.

Labor time. Replacing an in-tank fuel pump takes two to four hours at a shop. Labor rates vary by region but commonly fall between $75 and $150 per hour. In high-cost areas like California or New York, expect rates on the higher end.

Additional parts. Many jobs require new O-rings, seals, and sometimes the fuel sending unit. If the fuel filter is integrated into the pump assembly, that is included. If your car has a separate inline filter, you should replace it at the same time.

Location. Urban areas with a higher cost of living typically have higher labor rates than rural areas.

Can You Drive with a Bad Fuel Pump?

No, it is not safe or recommended to drive with a failing fuel pump. A bad fuel pump can leave you stranded at any moment, and it can also cause serious engine damage. When the pump fails completely, the engine will not get any fuel and will stall immediately. More importantly, a failing pump can send debris or metal shavings into the fuel system, potentially damaging the fuel injectors, fuel rail, and even the engine itself. The cost of cleaning or replacing those components is far higher than replacing the pump early.

Driving with a failing fuel pump also creates a safety risk. Sudden engine power loss on a highway or in heavy traffic could lead to an accident. If you suspect a fuel pump problem, have the vehicle towed to a repair shop rather than risk driving it.

How to Test the Fuel Pump on a 2013 Altima

Before spending money on a replacement, you can perform a few simple tests to confirm the fuel pump is the problem.

  1. Listen for operation. Turn the ignition to the ON position without starting the engine. You should hear a humming sound from the fuel tank area for two to three seconds as the pump primes the system.
  2. Check fuel pressure. Use a fuel pressure gauge connected to the fuel rail test port. For most Nissan Altima models, the fuel pressure should be between 49 and 56 psi. If the pressure is significantly lower or drops quickly after the pump stops, the pump is likely failing.
  3. Check the fuse and relay. Locate the fuse box and find the fuel pump fuse and relay. Swap the relay with a similar one, like the horn relay, to see if the pump works. If the fuse is blown, replace it and see if it blows again.
  4. Check for voltage at the pump. If you have a multimeter, you can test the electrical connector at the pump. With the key on, you should see 12 volts. If you have voltage but no noise, the pump is bad.

These tests take less than an hour and can save you from replacing a pump that is still working fine.

Tools and Parts You Will Need for a DIY Replacement

If you have intermediate mechanical skills, you can replace the fuel pump on a 2013 Altima yourself and save hundreds of dollars. Here is what you will need:

Tools:

  • Fuel pump locking ring removal tool
  • Fuel line disconnect tool
  • Socket set with extensions
  • Screwdrivers (flathead and Phillips)
  • Torque wrench
  • Multimeter (for testing)
  • Fuel pressure gauge (for testing)

Parts:

  • New fuel pump assembly (OEM or high-quality aftermarket)
  • New O-rings and seals
  • New fuel filter (if separate from the pump)
  • Fuel-resistant gloves
  • Safety glasses
  • Fire extinguisher (rated for chemical fires)

Safety equipment and precautions:

Work outside or in a very well-ventilated area because fuel vapors ignite easily. No smoking, no heat guns, and no shop lights with hot bulbs near the open tank. Disconnect the battery negative terminal before opening the fuel system. Relieve fuel pressure before disconnecting fuel lines to avoid spray. Keep a fire extinguisher nearby at all times.

Step-by-Step DIY Replacement Guide for a 2013 Altima

The 2013 Altima has an access panel under the rear seat cushion, which makes this job much faster than dropping the fuel tank. Here is the process:

Step 1: Relieve fuel system pressure. Remove the fuel pump fuse from the fuse box. Start the engine and let it run until it stalls. This releases pressure in the fuel lines. Try starting one more time to confirm no pressure remains.

Step 2: Disconnect the battery. Remove the negative terminal from the battery to prevent any electrical sparks while you work.

Step 3: Access the fuel pump. Remove the rear seat cushion by pushing down on the front clips and pulling up. You will find a metal access panel on the floor. Remove the screws or pry off the panel to expose the top of the fuel pump assembly.

Step 4: Disconnect electrical connectors and fuel lines. Carefully unplug the wiring harness from the top of the pump assembly. Use a fuel line disconnect tool to separate the quick-connect fittings. Have a container ready to catch any residual fuel. Take photos before disconnecting to ensure correct reassembly.

Step 5: Remove the old pump assembly. Use a fuel pump locking ring removal tool to loosen the metal ring. Turn it counterclockwise until it comes free. Slowly lift the pump assembly out of the tank. Be careful not to damage the fuel level sending unit as you remove it.

Step 6: Install the new pump assembly. Transfer any reusable components from the old pump to the new one if needed. Install the new O-ring and seal. Lower the new pump assembly into the tank, aligning it properly. Tighten the locking ring clockwise until it is snug. Do not overtighten.

Step 7: Reconnect everything. Reconnect the electrical connector and fuel lines. Make sure all connections are secure and free of debris.

Step 8: Restore power and test. Reconnect the negative battery terminal. Reinstall the fuel pump fuse. Turn the ignition to the ON position and listen for the pump to prime. Check for any fuel leaks around the access panel. Start the engine and let it idle. If it runs smoothly with no leaks, you are done.

This job takes two to three hours for most DIYers. If you are not comfortable working with fuel systems, have a professional handle the replacement.

How to Extend the Life of Your New Fuel Pump

Once you have replaced the fuel pump on your 2013 Altima, a few simple habits will help it last as long as possible:

  1. Keep your tank above a quarter full. This keeps the pump submerged and properly cooled.
  2. Replace the fuel filter on schedule. Most manufacturers recommend every 30,000 to 50,000 miles. If you drive in dusty conditions or stop-and-go traffic, shorten that interval to 15,000 to 20,000 miles.
  3. Use high-quality fuel. Top-tier gasoline contains higher levels of detergent additives that prevent varnish and deposit buildup inside the pump.
  4. Listen for unusual noises. A whining or buzzing sound from the rear of the car is a sign the pump is under stress. Address it immediately.
  5. Maintain the electrical system. A weak battery or failing alternator can cause the pump to operate at reduced voltage, making it work harder and run hotter.
  6. Manage moisture. Condensation forms inside the tank as temperatures fluctuate. Keeping the tank relatively full minimizes air space and reduces moisture buildup.

Following these habits can add tens of thousands of miles to the life of your fuel pump.

Final Thoughts

A failing fuel pump on your 2013 Nissan Altima is not a problem you can ignore. It can leave you stranded, damage your engine, and create a safety hazard on the road. The good news is that the 2013 Altima's design makes replacement easier than many other vehicles, and you have options ranging from a budget-friendly DIY job to a professional installation with a warranty.

Whether you choose an OEM replacement or a high-performance aftermarket pump like KEMSO, the key is to act as soon as you notice the symptoms.
