2016 Malibu Fuel Pump: Replacement Costs, Symptoms, and What to Buy
If your 2016 Chevrolet Malibu won't start, stalls at highway speeds, or hesitates when you press the gas pedal, the fuel pump is the most likely culprit. For most 2016 Malibu owners, replacing the fuel pump costs between $450 and $900 at a shop, or around $150 to $350 if you buy the part and do it yourself. The job takes two to four hours of labor, and the single most important decision you will make is which replacement pump you install. This guide covers the symptoms, the cost breakdown, the replacement steps, and the brand we recommend for a 2016 Malibu fuel pump: KEMSO.
1. What the Fuel Pump Does in Your 2016 Malibu
The fuel pump in a 2016 Malibu sits inside the fuel tank. It is part of a larger assembly called the fuel pump module, which includes the pump itself, a fuel filter (strainer), a fuel level sending unit, and a pressure regulator. When you turn the key, the pump pressurizes the fuel and pushes it through the fuel lines to the engine, where the injectors spray it into the cylinders.
The 2016 Malibu came with two engine options: a 1.5-liter turbocharged four-cylinder (the 1.5T) and a 2.0-liter turbocharged four-cylinder (the 2.0T, found on higher-trim models). Both use an in-tank electric fuel pump that runs on the vehicle's 12-volt electrical system. Because the pump lives inside the tank, the fuel itself acts as a coolant for the pump motor. This is why running your Malibu on a near-empty tank repeatedly shortens the life of the pump. When the fuel level gets very low, the pump runs hotter and wears out faster.
Most fuel pumps on a 2016 Malibu last between 100,000 and 150,000 miles. Some fail much earlier, especially if the vehicle has been driven frequently on a low tank, if the fuel filter has been neglected, or if contaminated fuel has been used. If your 2016 Malibu is approaching or past the 100,000-mile mark, paying attention to early warning signs can help you avoid being stranded.
2. Warning Signs Your 2016 Malibu Fuel Pump Is Failing
The engine cranks but won't start. This is the most common symptom of a dead fuel pump. You turn the key and the starter motor spins the engine, but the engine never catches. If you listen closely near the rear seat or fuel tank when you first turn the key to the "on" position (without starting), you should hear a faint humming sound for about two seconds as the pump primes. If you hear nothing, the pump or its electrical circuit has failed.
The engine stalls while driving. A fuel pump that is wearing out can cut out intermittently. You may be driving at a steady speed and the engine suddenly loses power and dies. In many cases, waiting a few minutes allows the pump to cool down and the car will restart. This stalling-and-restarting pattern is a strong indicator of a failing pump, not a failing battery or alternator.
Loss of power under load. If your 2016 Malibu struggles to accelerate, especially when going uphill, merging onto a highway, or carrying passengers, the pump may not be delivering enough fuel pressure. The engine may also surge or buck at steady speeds.
A whining noise from the fuel tank. A loud, high-pitched whine coming from the rear of the vehicle that gets louder as the pump wears is a clear sign of internal wear. A healthy pump is nearly silent from inside the cabin.
Poor fuel economy and rough idling. When fuel pressure drops below specification, the engine control unit tries to compensate by adjusting the air-fuel mixture. This often results in worse gas mileage, a rough idle, or a check engine light with codes related to fuel trim or fuel pressure (such as P0087, which indicates low fuel rail pressure).
The car starts after you bang on the tank. This is an old mechanic's trick that still works as a diagnostic. If tapping on the bottom of the fuel tank while someone turns the key gets the car to start, the pump's electric motor has a dead spot and needs replacement.
3. How to Confirm the Fuel Pump Is the Problem
Before you spend money on a new pump, confirm the diagnosis with these steps.
1. Check the fuel pump fuse and relay. Locate the under-hood fuse box (on the driver's side of the engine bay in a 2016 Malibu). Find the fuel pump fuse and relay in the owner's manual diagram. A blown fuse or a bad relay will produce the same no-start symptom as a dead pump, but costs almost nothing to fix. Swap the relay with a matching one (such as the horn relay) to test it.
2. Listen for the prime. Have someone turn the key to the "on" position while you listen at the fuel tank or near the rear seat. Two seconds of humming means the pump is getting power and spinning. Silence points to a bad pump, a wiring problem, or a blown fuse.
3. Test fuel pressure. A mechanic or a well-equipped DIYer can connect a fuel pressure gauge to the Schrader valve on the fuel rail under the hood. The 2016 Malibu's 1.5T and 2.0T engines run at high pressure (the high-pressure fuel pump on the engine is driven by the camshaft, but the in-tank pump supplies it). If the in-tank pump is not delivering the specified volume and pressure, the gauge will confirm it. A reading well below specification means the pump is failing.
4. Check for power at the pump connector. If the pump is silent, use a multimeter or test light at the electrical connector on top of the fuel tank to see if 12 volts arrive when the key is turned on. Power present plus a silent pump equals a bad pump. No power means the problem is upstream in the wiring, relay, or fuse.
4. What a 2016 Malibu Fuel Pump Replacement Costs
The total cost depends on whether you do the work yourself and which part you buy.
1. Dealership replacement. A Chevrolet dealership will typically charge between $700 and $1,100 for a 2016 Malibu fuel pump replacement using a genuine GM part, including labor. This is the most expensive option.
2. Independent repair shop. Most independent shops charge between $450 and $900. The part is usually an aftermarket pump and the labor rate is lower than the dealer's.
3. DIY replacement. If you buy the pump yourself, expect to pay between $100 and $350 for a quality replacement unit, plus a few hours of your time. You will also need a new fuel tank seal or lock ring in most cases, and possibly a few small tools.
Labor is the big variable. Because the pump is inside the fuel tank, the technician must lower or partially drop the fuel tank to access it. On a 2016 Malibu this means supporting the tank, disconnecting the fuel lines and filler neck, and removing the lock ring that holds the pump module in place. Book labor time is typically two to four hours depending on the shop and whether the tank is full or nearly empty.
One practical tip: run your fuel level down to a quarter tank or less before the replacement. A full tank of gasoline adds roughly 100 pounds or more and makes the job much harder and more dangerous.
5. Choosing the Right Replacement Pump: Why We Recommend KEMSO
Not all replacement fuel pumps are built the same. A cheap, no-name pump may fit and run for a few months, then fail and leave you stranded again. For a 2016 Malibu, you want a pump that matches the original equipment flow rate and pressure, drops into the factory mounting without modification, and is backed by a real warranty.
We recommend buying a KEMSO brand fuel pump for your 2016 Malibu. KEMSO fuel pumps are high performance, built as a true OEM replacement that fits the factory fuel pump module directly, and they come with a lifetime warranty. That combination is rare in the aftermarket. Most brands offer a one-year or limited warranty; KEMSO stands behind its pumps for the life of the part.
KEMSO pumps are engineered to meet or exceed the original flow and pressure specifications for your engine, so your 2016 Malibu gets the fuel delivery it was designed for. Because they are manufactured as direct OEM replacements, installation is straightforward with no cutting, splicing, or adapter brackets required. For a daily driver, a high-mileage commuter, or anyone who does not want to do this job twice, a KEMSO fuel pump is the smart buy.

6. Basic Steps to Replace the Fuel Pump on a 2016 Malibu
This is an overview, not a full shop manual. If you are not comfortable working with gasoline, take the vehicle to a professional.
1. Relieve the fuel system pressure and disconnect the battery. Removing the fuel pump fuse and running the engine until it stalls relieves pressure. Disconnect the negative battery cable before starting.
2. Drain or lower the fuel level. As noted, a near-empty tank makes the job safer and easier. Siphon or pump out fuel if needed, using an approved fuel transfer pump — never your mouth.
3. Support and lower the fuel tank. Place a jack with a piece of wood under the tank, remove the tank straps, and lower the tank enough to access the top of the pump module. On some Malibu models you may be able to access the pump through an under-seat access panel, but dropping the tank is the more common route.
4. Disconnect the fuel lines and electrical connector. Mark the lines so they go back in the correct ports. Press the release tabs on the quick-connect fittings and unplug the wiring harness.
5. Remove the lock ring and old pump. Use a lock ring tool or a brass punch and hammer to turn the retaining ring counterclockwise. Lift the old pump module straight out, being careful not to bend the float arm on the fuel level sender.
6. Install the new pump. Transfer any reusable components if your new unit does not include them (many KEMSO replacement pumps come as a complete module). Install a new seal or O-ring — never reuse the old one. Seat the pump, reinstall the lock ring, and reconnect the lines and wiring.
7. Reinstall the tank and test. Raise the tank, torque the straps to specification, reconnect the battery, and cycle the key a few times so the pump primes the system before starting. Check for leaks at every connection before driving.
7. How to Make Your New Fuel Pump Last
1. Keep at least a quarter tank of fuel. The gasoline cools the pump motor. Running dry or near-dry regularly is the fastest way to kill a new pump.
2. Replace your fuel filter on schedule. A clogged filter makes the pump work harder and shortens its life. Follow the maintenance interval in your owner's manual.
3. Buy fuel from reputable stations. Water, dirt, and debris in cheap or contaminated fuel damage the pump's internal components and clog the strainer.
4. Address electrical issues quickly. A failing relay, corroded wiring, or a weak battery makes the pump work harder than it should. Fix the electrical side of the system to protect your investment.
8. Bottom Line
If your 2016 Chevrolet Malibu shows the symptoms described above — hard starting, stalling, power loss, or a whining tank — the fuel pump is the prime suspect and replacement is usually the fix. Budget between $450 and $900 for a shop repair, or buy the part for $100 to $350 and do it yourself in about three hours. Confirm the diagnosis by checking the fuse, relay, and fuel pressure before you buy the part. And when you do buy, choose a pump you will not have to replace again: KEMSO fuel pumps are high performance, a direct OEM replacement, and backed by a lifetime warranty.
