2016 Fuel Pump: The Complete Guide to Symptoms, Replacement, and Choosing the Right Part
The bottom line: If your 2016 vehicle is experiencing hard starts, stalling, loss of power, or a whining noise from the fuel tank area, the fuel pump is likely failing. Replacing it promptly with a high-quality OEM or performance replacement, such as those from KEMSO, restores reliable fuel delivery and prevents costly breakdowns. This guide covers everything from symptoms and diagnostics to step-by-step replacement and maintenance tips.
What Does a 2016 Fuel Pump Do?
An electric fuel pump assembly sits inside the fuel tank and delivers pressurized fuel from the tank to the engine's fuel injectors. In most 2016 models, the pump is part of a module that also includes the fuel level sending unit and a built-in filter . The pump is rated for a specific pressure—for example, a Polaris General 2016 requires 58 ± 2 psi (400 ± 14 kPa) . When you turn the key to "ON," the ECU activates the pump to pressurize the system for startup .
The pump uses the surrounding fuel for cooling and lubrication. Running the tank consistently low causes the pump to overheat, which is a primary cause of premature failure .
Common Symptoms of a Failing 2016 Fuel Pump
Recognizing these signs early can save you from being stranded:
- Difficulty Starting: The engine cranks longer than normal or fails to start because the pump cannot build enough pressure .
- Stalling: The engine stalls, especially under load, during acceleration, or at highway speeds, due to insufficient fuel delivery .
- Loss of Power / Sputtering: You feel hesitation, sputtering, or a general lack of power when pressing the gas pedal. This is a common sign of low fuel pressure .
- Whining Noise from the Fuel Tank: A healthy pump hums quietly. A loud whining or buzzing sound indicates the pump is working harder than it should or its bearings are wearing out .
- Decreased Fuel Economy: An inefficient pump that cannot regulate pressure correctly forces the engine to run rich or lean, hurting gas mileage .
- Check Engine Light: A faulty fuel pump can trigger the Check Engine Light, often with diagnostic trouble codes (DTCs) related to fuel pressure or pump performance .
How to Diagnose a 2016 Fuel Pump Problem
Before buying a new pump, follow these steps to confirm the issue:
Step 1: Check the basics. Ensure the fuel pump fuse and relay are good, and the battery has at least 10.0 volts during cranking. The ECU will not operate the pump below that voltage .
Step 2: Listen for the pump. Turn the key to "ON" (not start). You should hear the pump prime for 2–3 seconds. If you hear nothing, the pump may not be getting power or has failed.
Step 3: Test voltage at the pump connector. Disconnect the harness from the pump module. Connect a DC voltmeter across the power and ground terminals in the vehicle-side plug. Turn the key on and verify a minimum of 10 volts is present .
Step 4: Check continuity. If voltage is present, turn the key off and use an ohmmeter to check for continuity across the pump terminals. If there is no continuity, the pump motor is open and must be replaced .
Step 5: Measure fuel pressure. Use a fuel pressure gauge adapter to check pressure at the rail. For a Polaris General 2016, the specification is 58 ± 2 psi . If pressure is out of spec, replace the pump assembly.
2016 Fuel Pump Replacement: A Step-by-Step Guide
Replacing a 2016 fuel pump is a moderately complex DIY job. Always work in a well-ventilated area, disconnect the battery negative cable, and keep a Class B fire extinguisher nearby .
Tools You'll Need:
- 10mm and 12mm sockets, ratchet, extensions
- Flat trim panel tool
- Fuel line quick-disconnect tool (5/16")
- Brass drift punch and dead-blow mallet (to avoid sparks)
- Inch-pound torque wrench
- Shop towels, drain pan, fuel-safe container
- Nitrile gloves and safety glasses
Step 1: Relieve fuel pressure. Remove the fuel pump fuse or relay, start the engine, and let it stall. Crank 2–3 more seconds. Disconnect the battery negative cable .
Step 2: Access the pump. On most cars, the pump is under the rear seat or in the trunk. Flip up the seat, remove the service cover fasteners, and clean the area around the module to prevent debris from falling into the tank .
Step 3: Disconnect lines and wiring. Disconnect the electrical connector. Use a fuel line quick-disconnect tool to release the quick-connect fitting. Cap the lines to keep dirt out .
Step 4: Remove the lock ring. Use a brass drift punch and dead-blow mallet to tap the lock ring counterclockwise until it releases. Brass reduces spark risk .
Step 5: Lift the pump module out. Carefully lift the module straight up, angling it to clear the float arm. Have a fuel-safe container ready—fuel will drip. Remove the old tank seal O-ring .
Step 6: Install the new module. Place the new tank seal O-ring in the tank groove. Lower the new module in, making sure the float arm is not bent. Align the orientation marks. Install the lock ring and tap it clockwise until fully seated. Torque if applicable (e.g., 44 in-lbs for some models) .
Step 7: Reconnect and test. Reconnect fuel lines until you hear a "click." Reconnect electrical. Reinstall the fuse/relay. Turn the key to ON for 5 seconds, then OFF for 5 seconds, repeating 2–3 times to prime the system. Check for leaks. Start the engine and verify pressure .

Maintenance Tips to Extend the Life of Your 2016 Fuel Pump
Preventive care is the simplest way to avoid a future fuel pump failure:
- Keep the fuel tank above 1/4 full. The pump is cooled and lubricated by the fuel. Running low consistently causes overheating and premature wear .
- Use high-quality fuel. Top-tier gasoline from reputable stations helps prevent varnish and deposit buildup in the tank and on the pump's inlet filter .
- Replace the in-tank filter sock. This strainer keeps debris out. It can become clogged over time, especially if the tank has contamination. Replace it whenever you service the pump .
- Use a fuel stabilizer for storage. If the vehicle is stored for long periods, add a stabilizer to prevent fuel degradation and corrosion .
- Avoid ethanol-blended fuels if possible. High ethanol content can corrode fuel system components and cause pump problems over time .
Cost of 2016 Fuel Pump Replacement
The total cost depends on the vehicle, whether you use OEM or aftermarket parts, and labor rates. For a 2016 Dodge Ram 1500, expect to pay between $400 and $1,000 for the entire job including parts and labor . Aftermarket pumps like KEMSO are often more affordable than dealership OEM parts, but do not sacrifice quality or reliability. Genuine OEM pumps for models like the 2016 Hyundai Veloster start around $150–$300 for the part alone .
In summary, the 2016 fuel pump is a critical component that requires attention at the first sign of trouble. By understanding the symptoms, performing a methodical diagnosis, and following the proper replacement procedure, you can keep your vehicle running reliably. For the best performance, durability, and peace of mind, choose a KEMSO high-performance fuel pump backed by a lifetime warranty.
