2006 Nissan Altima Fuel Pump Problems [Symptoms & Fixes]
If you’re experiencing some issues with your 2006 Nissan Altima that look like the fuel pump is the main culprit, this post is for you.
After reading this post, you’ll be able to tell if your Nissan Altima fuel pump is bad. We’ll also provide some recommendations on how to fix the fuel pump in your car.
So, let’s get started.
How to tell if Your 2006 Nissan Altima Fuel Pump is Bad
If your 2006 Nissan Altima’s fuel pump is bad, here are some of the problems you may notice:
Sputtering Engine
A bad fuel pump causes your Nissan Altima’s engine to sputter or backfire while making unusual sounds.
This is usually due to the inconsistent flow of gas to the fuel injection system in your vehicle. So, get your mechanic to run some diagnostic checks and replace the faulty fuel pump.
Difficulty Starting the Vehicle
Another common sign that your 2006 Nissan Altima’s fuel pump is bad is difficulty in starting the vehicle. This difficulty is due to the lack of sufficient pressure generated by the fuel pump.
Since starting your vehicle requires more cranks than usual, it makes sense to replace the fuel pump to avoid time wastage.
You should also check the fuel pump relay, as it can fail in an open position and prevent voltage from reaching the fuel pump.
Stalling Engine
When driving your Nissan Altima and it starts decelerating and stalls on the road, shutting itself down, the fuel pump may be the problem.
An overheated fuel pump with a stalling engine usually indicates a big problem with the fuel pump motor.
Tow your car to the nearest auto repair shop and get the fuel pump/motor checked. Replacing the fuel pump may be necessary to avoid future occurrences.
Loss of Engine Power
When your 2006 Nissan Altima is under stress, such as transporting heavy loads, driving uphill, or accelerating, you may experience a sudden loss of power.
Engine shut-downs are due to the inability of the weakened fuel pump to keep up with these stressful demands.
If you’re experiencing this, get your vehicle checked by a certified mechanic and replace the fuel pump—if needed.
Weird Whining Sounds
A damaged fuel pump makes a weird, whining sound from the rear of your Nissan Altima. This is unlike the quiet hum you hear when you turn the key in the ignition.
Your mechanic should check the fuel pump and determine if it needs to be changed or fixed. Check the fuel filter and inlet screen to ensure they are not clogged.
But if the whining sound persists or the fuel pump looks worn out, replace it immediately.
Check Engine Light Turns On
If you’re driving your vehicle and the engine suddenly vibrates while the check engine indicator illuminates the dashboard, your fuel pump has gone bad.
You may also notice that the fuel gauge displays inaccurate readings and becomes inoperable when the fuel in your tank is less than half.
You will have to replace the fuel pump and get the fuel gauge checked and adjusted.
Excessive Fuel Consumption
If you discover you’re filling up your Nissan Altima more than usual, it may be a problem with the fuel pump.
Get your mechanic to check what is wrong with the fuel pump and replace it if necessary, especially if a valve within the fuel pump doesn’t open.
Surging Vehicle
When driving your Nissan Altima and it surges as if you just pressed harder on the gas pedal, something may be wrong with your fuel pump.
Your fuel pump should be examined if this occurs often and randomly at a consistent speed.
Your mechanic should examine the fuel pump to see if it can be fixed. If not, replace it with a new unit.
Can You Drive with a Bad Fuel Pump?
No, you cannot drive your Nissan Altima with a bad fuel pump.
If the fuel pump is bad, it won’t transfer gas to your engine. This makes it practically impossible to start your 2006 Nissan Altima.
Driving with a bad fuel pump is a bad idea, as you may damage other engine components. This will cost you more money to fix or replace in the long run.
How Much Does It Cost to Replace the Fuel Pump in a 2006 Nissan Altima?
According to RepairPal, it will cost an average of $742 to $875 to replace a 2006 Nissan Altima fuel pump. Labor costs range from $74 to $94, while components are priced from $668 to $781.
These price ranges do not include fees and taxes or location. Bear in mind that related repairs, such as replacing the fuel filter, checking the fuel line, etc., may be required.
Has Nissan Ever Recalled Any Altima Model Years for Fuel Pump Issues?
Nissan North America Inc. (Nissan) once recalled certain 2019 Altima vehicles equipped with 2.5-liter engines.
The fuel pump lock ring or retainer clip fails to engage properly and may cause fuel to leak. This increases the risk of a crash when the fuel tube disconnects and the engine stalls.
As a result, these Nissan Altima vehicles did not comply with the requirements of FMVSS (FMVSS) number 301, ‘Fuel System Integrity.’
Prematurely failed fuel pumps have consistently affected several Nissan Altima model years, ranging from 2001 to 2015.
Tips to Make Your 2006 Nissan Altima Fuel Pump Last Longer
Most fuel pumps can last up to 100,000 miles, while a few last even longer. You can be in the latter category if you stick to the following tips:
- Only use a fuel filter specified by the manufacturer.
- Buy fuel from gas stations that take care of their nozzles and underground tanks.
- Change the fuel filter every 30,000 miles or according to the manufacturer’s recommendation. Check the inlet screen from time to time.
- Ensure your fuel tank is nearly always half full to prevent the fuel pump from overheating due to lack of sufficient fuel. The gas acts as a coolant to cool fuel pumps.
- Avoid contaminated fuel.
- Avoid driving uphill or carrying heavy loads, as this stresses the fuel pump.
