2006 Uplander Fuel Pump: Complete Replacement Guide for Owners

If you drive a 2006 Chevrolet Uplander and you are dealing with hard starts, engine sputtering, or a no-start condition, the fuel pump is very likely the source of the problem. The fuel pump on your Uplander is an electric unit mounted inside the fuel tank, and when it fails, the engine simply cannot get the pressurized fuel it needs to run properly. Replacing the fuel pump on a 2006 Uplander is a moderately involved job that requires accessing the top of the fuel tank through the passenger compartment, and the total cost typically falls between $400 and $700 depending on whether you choose a dealership, an independent shop, or a do-it-yourself approach. This guide walks you through the warning signs, the replacement process, the genuine part numbers you need, and how to pick a reliable replacement pump that will last.

Your 2006 Uplander uses a returnless fuel system where the pump delivers fuel at a regulated pressure to the engine. The pump sits inside the fuel tank along with the fuel level sending unit, and the entire assembly is accessed through a service panel under the rear seats . Most factory fuel pumps are designed to last the life of the vehicle, but they can fail prematurely due to contaminated fuel, running the tank too low on a regular basis, or simply age-related wear on the electric motor inside the pump . Understanding what to look for and how to respond can save you from being stranded and help you avoid paying unnecessary diagnostic fees.

Common Symptoms of a Failing Fuel Pump in Your 2006 Uplander

Recognizing the early signs of fuel pump failure can save you from a sudden breakdown. The symptoms can develop gradually or appear without warning, and they are similar to issues caused by other fuel system components, so proper diagnosis matters.

• Engine cranks but will not start – If your Uplander's engine turns over normally but refuses to fire, the fuel pump may not be generating enough pressure to deliver fuel to the injectors . A no-start condition is the most obvious sign that the pump has stopped working entirely.
• Hard starting and long crank times – When the pump is weak but not dead, the engine may crank for several seconds before finally starting . This is often worse after the vehicle has sat for a while because the fuel pressure bleeds down when the pump is off.
• Loss of power under acceleration – A failing pump cannot maintain the required fuel pressure when you demand more power, causing the engine to hesitate, stumble, or feel like it is starving for fuel . This is especially noticeable when climbing hills or merging onto highways.
• Engine sputtering or stalling – If the fuel flow is inconsistent, the engine may sputter at idle or stall completely, sometimes at the worst possible moment . Stalling at idle is often caused by the pump overheating, which happens when the fuel level is low and the pump is not submerged in enough fuel to stay cool.
• Whining noise coming from the fuel tank – A healthy fuel pump operates quietly. If you hear a loud whine or hum coming from the rear of the vehicle, especially when the tank is low, the pump is likely struggling and may be close to failure .
• Decreased fuel efficiency – A pump that is not maintaining correct pressure forces the engine to run richer or leaner than designed, which can noticeably reduce your miles per gallon . If you notice your fuel economy dropping without another obvious cause, the pump deserves a look.
• Check engine light with fuel pressure trouble codes – Codes like P0087 (fuel rail pressure too low) or P0191 (fuel pressure sensor range/performance) often point directly to a weak or failing fuel pump . A scan tool can confirm the diagnosis before you spend money on parts.

Before you condemn the fuel pump, it is worth checking a few other components. A clogged fuel filter, a faulty fuel pump relay, or a bad fuel pressure regulator can all produce similar symptoms . If you have access to a fuel pressure gauge, you can verify the pump's output. On the 2006 Uplander with the 3.5L V6 engine, the fuel pressure should be around 50-60 psi with the key on and the engine running or cranking. Anything below this range, especially when the engine is under load, points to a weak pump.

How Much Does It Cost to Replace a Fuel Pump on a 2006 Uplander?

Replacement costs vary widely depending on where you take the vehicle and whether you use genuine GM parts or aftermarket alternatives. Here is a breakdown of what you can expect to pay:

Dealership pricing. A Chevrolet dealership will typically charge between $650 and $850 for a fuel pump replacement on a 2006 Uplander. This includes the pump assembly itself, which costs roughly $250 to $400 if purchased as a genuine GM part, plus labor at the dealership's hourly rate, which tends to run higher than independent shops . Dealership technicians are trained specifically on GM vehicles, and they use manufacturer-recommended parts that carry their own warranty .

Independent shop pricing. An independent mechanic will usually quote between $450 and $650 for the same job . Independent shops have lower overhead than dealerships, and they can use aftermarket parts that cost less than genuine GM components. Prices can vary significantly by region, so it is always a good idea to get at least two or three quotes before committing to a repair.

Do-it-yourself cost. If you are comfortable working on your own vehicle, the parts will cost between $80 and $250 depending on the brand and whether you buy a complete module assembly or just the pump itself . Names like Airtex, Carter, Delphi, and GMB all make fuel pump modules for the 2006 Uplander. You will also need basic hand tools, a screwdriver to pry the access cover, and possibly a fuel line disconnect tool. There is no way around the labor if you do it yourself—expect to spend two to four hours depending on your skill level .

For reference, the average national cost for fuel pump replacement across all vehicles is roughly between $611 and $894 including parts and labor . The Uplander falls on the lower end of that range because the fuel pump is accessible through a service panel under the rear seats, which means the mechanic does not need to drop the fuel tank .

Where Is the Fuel Pump Located on Your 2006 Uplander?

The fuel pump on your Uplander is mounted inside the fuel tank, which sits under the rear of the vehicle. To access the pump, you do not need to remove the fuel tank on the 2006 model. Instead, there is a service hole cover in the floor pan under the rear seats that provides access to the top of the pump assembly .

The general access procedure works like this:

1. Remove the rear seats. The second and third row seats need to be unbolted and lifted out of the vehicle to expose the carpet underneath. On the 2006 Uplander, the rear seat cushions can usually be pulled upward to release them, and then the seat back fasteners can be accessed with a socket wrench .
2. Lift the carpet. Once the seats are out, the carpet needs to be pulled back or lifted in the area where the fuel pump access panel is located. This gives you access to the sheet metal cover .
3. Pry off the service hole cover. A flat blade screwdriver is typically all you need to carefully pry the metal or plastic cover off the floor pan. Underneath, you will see the top of the fuel pump module and its electrical connector .

On 2007 and later models, the procedure is slightly more involved because you have to disassemble rear trim components to lift the carpet . But on the 2006 model, the access is straightforward, which is one of the reasons the replacement cost is lower than many other vehicles .

Step-by-Step Fuel Pump Replacement for the 2006 Uplander

If you are planning to replace the fuel pump yourself, here is the step-by-step process. Before you start, disconnect the negative battery cable and relieve the fuel system pressure by removing the fuel tank cap and pulling the fuel pump fuse while the engine is running until it stalls . Make sure you have a fire extinguisher nearby and work in a well-ventilated area.

Step 1: Gain access to the fuel pump. Remove the rear seats and lift the carpet as described above. Carefully pry off the service hole cover with a screwdriver .

Step 2: Disconnect the electrical connector. The fuel pump electrical connector is located on top of the pump module. Depress the release tab and pull upward to disconnect it. It may be stiff, so a small pair of needle nose pliers can help .

Step 3: Disconnect the fuel supply line. The fuel supply line connects to a fitting on the top of the pump module. Remove the clip that holds the fitting in place, then pull the fitting straight upward. Inspect the O-ring inside the fitting—if it is damaged or worn, replace it before reconnecting .

Step 4: Remove the retaining ring or bolts. On the 2006 Uplander, the pump module is held in place by a large plastic retaining ring that you unscrew counterclockwise. You may need a special fuel pump removal tool, which is essentially a large wrench that grips the tabs on the retaining ring . If your vehicle uses bolts instead, remove them with a socket wrench.

Step 5: Lift out the pump assembly. Carefully lift the pump and sending unit assembly out of the fuel tank. Be gentle—the fuel inlet strainer and the float arm for the fuel level sensor are delicate and prone to damage if you angle the assembly the wrong way .

Step 6: Transfer components to the new pump. If you bought a bare pump rather than a complete module assembly, you will need to transfer the fuel level sending unit, the strainer, and the rubber mounting grommet from the old assembly to the new one. A complete module assembly skips this step and is usually worth the extra money because it is a direct drop-in replacement .

Step 7: Install the new assembly. Position the new pump assembly in the fuel tank opening, making sure the float arm does not bind against the side of the tank. Press it down evenly and tighten the retaining ring clockwise until it is snug. If you are working on a model with a triangle mark on the ring, align it with the S mark on the tank .

Step 8: Reconnect everything. Reinstall the fuel supply line, making sure the clip snaps into place, and reconnect the wiring harness. Replace the service hole cover, reinstall the carpet and seats, and reconnect the battery.

Step 9: Test the repair. Turn the key to the ON position without cranking the engine for about two seconds to let the fuel pump pressurize the system. Do this two or three times, then start the engine. Check for fuel leaks around the pump module, and verify that the fuel gauge is reading correctly .

One thing to keep in mind is that the pump module gasket or seal should be replaced whenever you have the assembly out. Many aftermarket assemblies come with a new gasket, but if you are reusing the old one, it may leak and let fuel odors into the cabin .

Genuine GM Part Numbers for the 2006 Uplander Fuel Pump

When you order a replacement fuel pump, you want to make sure it is the correct part for your specific engine and drivetrain configuration. The 2006 Uplander came with either a 3.5L V6 engine or a 3.9L V6 engine, and the fuel pump module is different depending on which engine you have . There are also differences based on whether your vehicle is standard wheelbase or extended wheelbase .

Here are the common part numbers you will encounter when shopping for a replacement fuel pump module for the 2006 Uplander:

• GM original part numbers: 19121350, 19153047, 19149231, 15781790, 19151717, 25378284, 28073743 . These are the numbers you will see on genuine GM boxes, and they are the reference points that aftermarket manufacturers use to ensure compatibility.
• ACDelco part numbers: MU1354 and MU1673 are the ACDelco equivalents for the 2006 Uplander fuel pump module .
• Airtex / Carter part number: E3717M or E3710M covers the 2006-2007 Uplander with the 3.5L and 3.9L V6 engines. These are among the most commonly stocked aftermarket options .
• Bosch part number: 67504 or 67507 are Bosch's equivalents, which are also widely available .
• Composite interchange numbers: FG0405, FG0490, P76233M, SP6405M, M10049, and P76234M are additional interchange numbers used across brands like Spectra Premium and US Motor Works .

The E3717M (also listed as E3710M) is the one you will see most often for the 2006 Uplander with the 3.5L V6 engine . These module assemblies include the fuel pump, the fuel level sending unit, the strainer, and the mounting hardware in one unit, which makes installation much cleaner than replacing just the pump motor .

If you are unsure which version your Uplander has, check the VIN and look for the RPO code on the sticker in the glove box or driver's door jamb. The engine code is usually listed as LZ4 for the 3.5L or LZ9 for the 3.9L . You can also call a dealership parts department with your VIN, and they will verify the correct part number for your vehicle.

How to Choose the Right Replacement Fuel Pump

Not all fuel pumps are created equal, and picking the wrong one can leave you stranded again in a year or two. Here is what to look for when comparing options:

1. Buy a complete module assembly, not just the bare pump. Modern fuel injection systems use an integrated module that contains the pump, the level sender, the pressure regulator, and the strainer. Replacing just the pump motor means reusing older components, which is a false economy—the sender can fail just as easily as the pump . A complete assembly is a direct-fit replacement that restores the entire fuel delivery and fuel level monitoring system.

2. Choose a recognized brand with a track record. Names like ACDelco, Delphi, Bosch, Carter, Airtex, and Spectra Premium all have decades of experience building fuel system components . They meet or exceed OEM specifications and carry warranties that protect you if the part fails early. Generic no-name parts from online marketplaces may look like a bargain, but they often use lower-grade materials and shorter-lasting motors.

3. Check for a warranty. Most reputable fuel pump brands offer at least a limited lifetime warranty . This is important because even a quality fuel pump can fail prematurely due to contamination or abnormal voltage. A warranty gives you recourse without having to buy a second pump.

4. Confirm the part includes the necessary hardware. Some pump modules come with the lock ring, gasket, and mounting hardware, while others do not . Read the product description carefully. If the gasket is not included, you will need to order it separately—reusing the old gasket is not advisable.

5. Verify fitment with your VIN. Fuel pump modules are sensitive to engine type, fuel system type, and even wheelbase length . Use the online fitment checkers on parts retailer websites, or call their customer service lines to confirm the part before you buy .

The estimated installation time for a professional mechanic is one to two hours, while a DIY installation runs two to four hours . That assumes you know your way around the rear seating area and are comfortable working with fuel system components.

Signs That Your Fuel Pump Is Not the Problem

Before you spend money on a new fuel pump, it pays to rule out the other common causes of fuel delivery problems:

• Clogged fuel filter. If the fuel filter has never been changed, it can restrict flow and produce symptoms similar to a failing pump. The fuel filter on the Uplander is located along the frame rail under the vehicle. Replacing it is a quick, inexpensive job .
• Faulty fuel pump relay. The relay is located in the underhood fuse block, and it can fail intermittently, cutting power to the pump . Swapping the relay with a known-good one is a quick test.
• Bad crankshaft or camshaft position sensor. If the engine computer does not receive the crankshaft position signal, it may not activate the fuel pump relay even though the pump itself is fine . If you have a scan tool, check for crankshaft sensor trouble codes.
• Fuel pressure regulator failure. A leaking regulator will cause fuel pressure to drop when the engine is off, resulting in extended cranking times on hot starts. If the regulator is on the fuel rail, a vacuum line with the smell of fuel is a dead giveaway .
