The Complete Guide to Your 2017 Kia Soul Fuel Pump: Symptoms, Replacement, and Costs

Your 2017 Kia Soul's fuel pump is its critical heart, delivering gasoline from the tank to the engine. When it fails, your car stops running. Recognizing early symptoms like engine sputtering, power loss, or hard starting can save you from costly roadside breakdowns and extensive repairs. Understanding replacement options, realistic pricing, repair procedures, and prevention strategies is essential for every 2017 Soul owner facing fuel pump issues.

The fuel pump is arguably one of the most vital components under your 2017 Kia Soul’s hood. It operates silently within the fuel tank, performing the crucial task of pressurizing gasoline and delivering it through fuel lines to the engine’s fuel injectors. Without the correct fuel pressure maintained consistently, the engine simply cannot run properly, or at all. When a fuel pump in a 2017 Soul begins to weaken or fails entirely, it manifests through distinct warning signs. Ignoring these signs often leads to being stranded or requiring a significantly more expensive tow and repair scenario. This guide dives deep into everything you need to know about the 2017 Kia Soul fuel pump.

The Role of the Fuel Pump in Your 2017 Soul

Think of the fuel pump as the heart of your Soul's fuel system. Its singular job is to draw gasoline from the tank and push it at high pressure (typically between 50-60 PSI for the Soul) through the fuel filter and fuel lines all the way to the engine compartment. There, the fuel rail distributes the pressurized fuel to individual fuel injectors. These injectors spray a precise mist of fuel into the engine’s combustion chambers, where it mixes with air and ignites to create power. The entire engine management system relies on the fuel pump maintaining this constant, specific pressure. Any drop in pressure or inconsistency in delivery disrupts the precise air-fuel mixture, leading to performance issues, poor fuel efficiency, or a complete inability to start or run.

Common Symptoms of a Failing 2017 Kia Soul Fuel Pump

Identifying fuel pump problems early is paramount. Look out for these frequent warning signs:

1. Engine Sputtering or Hesitation (Especially Under Load/RPM): A weak pump cannot maintain consistent pressure. When you accelerate hard, climb a hill, or sustain higher speeds demanding more fuel, the engine may sputter, hesitate, jerk, or lose power dramatically as the fuel supply dwindles momentarily. This may feel like the car is "bucking."
2. Loss of Power While Driving: This is a direct escalation of the sputtering symptom. The engine might suddenly lose significant power, making it difficult or impossible to maintain speed, even with the accelerator pedal pressed down. This is dangerous, especially in traffic.
3. Difficulty Starting the Engine: A failing pump may take longer to build sufficient pressure when you turn the key. You'll notice extended cranking (the engine turning over for several seconds) before it finally starts, or it might crank rapidly without starting at all. This often happens more frequently when the engine is warm.
4. Engine Stalling: The engine might start and idle roughly, only to die moments later. Or, it could stall unexpectedly while driving, especially during maneuvers like coming to a stop or turning corners. A complete pump failure causes immediate and permanent stalling.
5. Whining Noise from the Fuel Tank Area: A healthy pump emits a faint, low hum when activated. A pump nearing failure often develops a noticeable high-pitched whining or howling sound, originating from the rear of the vehicle near or under the back seat (location of the fuel tank/pump). The sound typically intensifies as the pump struggles or just before failure.
6. Decreased Fuel Efficiency: While less specific and easily attributed to other issues, an inefficient pump working harder to deliver inadequate pressure can sometimes lead to increased fuel consumption. The engine computer compensates for low pressure by increasing injector duration, burning more fuel.
7. Surging Engine: Occasionally, a failing pump might cause unpredictable, momentary bursts of higher pressure, leading to the engine suddenly surging or revving slightly without driver input.
8. Car Won't Start at All: This is the ultimate symptom of complete fuel pump failure. If the pump provides zero pressure, the engine cranks normally but will not fire or run, as no fuel reaches the injectors.

Why Do 2017 Kia Soul Fuel Pumps Fail?

Several factors can lead to the demise of a fuel pump:

1. Electrical Failure: This is the most common cause. The pump is powered by an electric motor. Wiring issues within the pump assembly (like corroded connectors), problems with the fuel pump relay (a switch that controls power to the pump), blown fuses, or faults in the wiring harness leading to the pump assembly can prevent the pump from receiving power or functioning correctly.
2. Contaminated Fuel/Debris: While the fuel pump has a built-in inlet strainer (often called a "sock"), extremely dirty fuel, sediment from a deteriorating tank, rust particles, or water contamination can bypass or clog this filter over time. This debris enters the pump mechanism, causing abrasion, wear, and eventual seizure or motor burnout. Running the tank extremely low frequently also draws debris settled at the tank bottom directly into the pump.
3. Overheating: The electric motor is cooled and lubricated by the surrounding fuel. Consistently driving with a very low fuel level means the pump isn't fully submerged, causing it to run hotter. This excessive heat accelerates wear and significantly shortens its lifespan. This is a major preventable cause of premature failure.
4. Wear and Tear: Like any mechanical/electrical component with moving parts, fuel pumps have a finite lifespan. Bearings wear out, internal contacts corrode, and the motor itself can simply wear down after 7 years and thousands of driving cycles. They typically last 100,000 miles or more, but many factors influence this.
5. Fuel Quality: Using consistently poor-quality gasoline, gasoline mixed with incorrect additives, or gasoline containing higher than acceptable levels of ethanol (beyond what the pump materials are designed for) can accelerate internal corrosion and component breakdown. Modern pumps are designed for E10; using fuels like E85 in a non-flex-fuel vehicle will cause rapid failure.
6. Manufacturing Defect: While less common after the initial vehicle warranty period, defective components or assembly flaws can lead to premature failure. Technical Service Bulletins (TSBs) or recalls sometimes address specific known pump issues in certain production batches.

Diagnosing a 2017 Soul Fuel Pump Problem

Confirming a faulty fuel pump is essential before undertaking expensive replacement. Here's how professionals diagnose it:

1. Check for Diagnostic Trouble Codes (DTCs): Mechanics connect an OBD-II scanner to the Soul's diagnostic port. Specific fuel system codes like P0087 (Fuel Rail/System Pressure - Too Low) or P0171 (System Too Lean Bank 1) strongly suggest fuel delivery issues, potentially including the pump. Note: The absence of codes does NOT rule out a failing pump, especially in early stages.
2. Listen for Pump Activation: When the ignition is turned to "ON" (without starting the engine), you should hear the fuel pump motor run for a few seconds to prime the system. No sound at all strongly indicates a power/relay/fuse issue or a dead pump. A loud, abnormal whine points towards pump distress.
3. Fuel Pressure Test: This is the definitive diagnostic step. A mechanic uses a specialized fuel pressure gauge connected to the Schrader valve test port on the engine's fuel rail. They measure:
   • Key-On Prime Pressure: Pressure when ignition is turned "ON."
   • Engine Running Pressure: Pressure at idle and various RPMs.
   • Pressure Holding/Leakdown: Pressure retention after engine shutoff.
     Low pressure readings, failure to reach specifications, or rapid pressure drop all confirm a fuel delivery problem, with the pump being the prime suspect if other components (like the pressure regulator) check out.
4. Electrical System Checks: Technicians will test voltage and ground at the fuel pump's electrical connector to ensure it's receiving the required power when commanded. They will also verify the condition and operation of the fuel pump relay and relevant fuses.
5. Rule Out Other Issues: Symptoms similar to fuel pump failure can be caused by a clogged fuel filter (though often integrated on the Soul), faulty fuel pressure regulator, bad crankshaft position sensor (prevents injector pulse), severe ignition problems, or major vacuum leaks. Diagnosis must systematically eliminate these possibilities.

2017 Kia Soul Fuel Pump Replacement: What You Need to Know

Replacing the fuel pump module assembly is a moderately complex task best performed by experienced DIYers or professionals.

1. Understanding the Assembly: The pump is not sold individually on the street level. It comes as a complete fuel pump module assembly. This integrated unit includes:
   • The Electric Fuel Pump itself
   • A Fuel Level Sending Unit (senses gas tank level)
   • An Inlet Strainer/Sock filter
   • The pump housing and reservoir
   • Necessary electrical connectors and hoses
2. Location: The assembly is mounted on top of the fuel tank, accessed under the rear seat cushion or cargo floor of the Soul. This requires removing interior trim panels and the access cover plate.
3. Safety First! Gasoline is extremely flammable! Disconnecting the battery is mandatory. The area must be well-ventilated. No sparks or open flames can be nearby. Work should ideally be done when the fuel tank is nearly empty to minimize fuel spillage and reduce weight. Special depressurization procedures for the fuel system must be followed to prevent gasoline spray when disconnecting fuel lines.
4. Procedure Overview:
   • Disconnect the negative battery cable.
   • Access the fuel pump module (remove rear seat/base, access cover).
   • Relieve fuel system pressure (often by removing the fuel pump fuse/relay and running the engine until it stalls).
   • Disconnect electrical connectors and fuel lines from the pump module.
   • Carefully clean the area around the module sealing surface.
   • Unbolt and remove the module locking ring (special spanner tool often needed).
   • Carefully lift out the entire module assembly.
   • Replace the seal/gasket on the tank opening (CRITICAL to prevent leaks!).
   • Install the new module assembly, ensuring it's properly aligned and seated.
   • Secure the locking ring tightly.
   • Reconnect fuel lines and electrical connectors.
   • Reinstall the access cover and trim.
   • Reconnect the battery.
   • Cycle the ignition several times to prime the system before attempting to start.
5. The Importance of Seal Replacement: The large O-ring or gasket that seals the pump assembly to the fuel tank flange MUST be replaced with a new one every time the assembly is removed. Reusing the old seal almost guarantees a dangerous fuel leak and vapors entering the cabin.

Choosing the Right Replacement Fuel Pump for Your 2017 Soul

Your choice significantly impacts reliability and cost:

1. OEM (Original Equipment Manufacturer): Purchased through a Kia dealership parts department. This is the exact part used when your Soul was built. Highest price, highest expected reliability and longevity, perfect fitment. Best choice if budget allows or the car is kept long-term.
2. Quality Tier-1 Aftermarket (Delphi, Bosch, Denso, ACDelco): Reputable brands that often manufacture the OEM pumps for various automakers. They meet or exceed OEM specifications. Excellent reliability, good value for money. Highly recommended balance. Ensure the part is specifically marked for the 2017 Soul.
3. Economy Aftermarket: Budget-friendly options from numerous brands. Quality and longevity vary significantly and are often sub-par. Many professional mechanics strongly advise against these due to high rates of premature failure, inaccurate fuel level readings, and potential fitment issues leading to leaks. Can be a costly gamble, potentially requiring another replacement far too soon.
4. Used/Remanufactured: Generally not recommended for critical parts like the fuel pump due to uncertain history, unknown wear, and significant potential for early failure. Leaks are also a major risk with used units.

Preventing Premature 2017 Soul Fuel Pump Failure

Prolong your fuel pump's life with these habits:

1. Avoid Consistently Running on "Empty": Keep your tank at least 1/4 full whenever possible. This ensures the pump is submerged in cool fuel, preventing overheating and drawing in sediment from the tank bottom. Letting the tank get very low consistently is a primary cause of accelerated pump wear.
2. Use Quality Fuel: Purchase gasoline from reputable, high-volume stations known for maintaining clean storage tanks. Avoid gas stations during tanker refueling when sediment is stirred up. If the Soul isn't a flex-fuel vehicle, never use E85 gasoline.
3. Replace the Fuel Filter When Recommended: If your Soul has an external fuel filter (some models integrate it with the pump module), replace it according to the scheduled maintenance interval (often around 30,000 miles). A severely clogged filter forces the pump to work excessively hard.
4. Address Contamination Immediately: If you suspect water or bad fuel was put in the tank (e.g., misfiring, poor running right after fill-up), have the tank drained and cleaned professionally to prevent damage to the pump and injectors.
5. Fix Electrical Problems Promptly: Issues with relays, fuses, or wiring related to the fuel pump circuit can stress the pump motor. Get electrical diagnostics done if you experience intermittent starting/running problems.

Warranty Coverage for 2017 Kia Soul Fuel Pumps

Understanding your coverage is crucial:

1. New Vehicle Limited Warranty: For 2017 Kia Souls, the original 5-year/60,000-mile bumper-to-bumper warranty has expired. The 10-year/100,000-mile Powertrain Limited Warranty generally does not cover the fuel pump, as it is considered an emissions-related component or part of the fuel system, not the powertrain (engine, transmission, etc.).
2. Emissions Warranty: Federal law mandates an Emissions Warranty, typically covering the fuel pump as a critical emissions-related part for 8 years or 80,000 miles. If your 2017 Soul has under 80,000 miles and is less than 8 years old (check your original in-service date!), a fuel pump failure MAY be covered under this warranty. Contact your Kia dealership with your VIN to confirm eligibility. Coverage varies by state and specific component.
3. Aftermarket Parts Warranty: Replacement fuel pump assemblies come with their own warranty, typically 1-3 years or 12,000-36,000 miles (varies significantly by brand and seller). Keep your receipt! This warranty covers the part itself if it fails prematurely under normal use, but usually does not cover labor unless installed by the selling shop.
