If you own a 2017 Kia Forte and suspect your fuel pump is failing, here is the bottom line: a fuel pump replacement for this vehicle typically costs between $1,286 and $1,439 at a professional shop, with labor running $135 to $198 and the part itself costing around $1,241 . For the 2017 model specifically, the annual repair cost averages $481, and the fuel pump is one of the more expensive repairs you will face . The good news is that you can save significant money by understanding the symptoms, knowing what to expect, and choosing the right replacement part. This guide walks you through everything you need to know, from spotting a bad fuel pump to completing the replacement.

What Does the Fuel Pump Do in Your 2017 Kia Forte?

The fuel pump's job is straightforward but critical: it delivers gasoline from the fuel tank to the fuel injectors at the correct pressure to keep your engine running smoothly in all conditions . In the 2017 Kia Forte, the pump is located inside the fuel tank. It uses an electric motor to suck fuel out of the tank, push it through a filter, and then send it to the injectors . If the pump fails to create enough pressure, your engine will not perform properly, and you may experience a "no start" condition .

Symptoms of a Bad Fuel Pump in Your 2017 Kia Forte

Recognizing the warning signs early can save you from being stranded or causing further damage to your vehicle. Here are the most common symptoms to watch for:

1. Difficulty Starting or No Start
The most obvious sign is when your Kia Forte takes longer to start than usual. If the fuel pump cannot supply enough fuel, the engine may crank for several seconds before firing up, or it may not start at all . In some cases, the car will start but then stall shortly after.

2. Loss of Power During Acceleration
A failing fuel pump cannot maintain consistent fuel pressure, especially when you need more power, such as merging onto a highway or climbing a hill. You will notice a lack of power or hesitation when you press the accelerator . This can feel like the car is running out of gas even when the tank is full.

3. Engine Sputtering or Stalling
If the fuel pump is on its way out, your engine may sputter or misfire, particularly at high speeds or under load. This happens because the pump is not delivering a steady flow of fuel, causing the air-fuel mixture to become inconsistent . The engine may stall without warning, which is dangerous in traffic.

4. Whining Noise from the Fuel Tank
A healthy fuel pump makes a quiet humming sound. If you hear a loud, high-pitched whining noise coming from the rear of the car near the fuel tank, it is a strong indicator that the pump is failing or has a clogged filter . This noise often gets louder as the problem worsens.

5. Poor Fuel Economy
When the fuel pump is not working efficiently, the engine may run rich (too much fuel) or lean (too little fuel), both of which hurt fuel economy. If you notice a sudden drop in miles per gallon, the fuel pump could be the culprit .

6. Check Engine Light
A failing fuel pump can cause a lean running condition, which will trigger the Check Engine Light on your dashboard . A mechanic can read the diagnostic trouble code to confirm the issue.

Is It Safe to Drive with a Bad Fuel Pump?

No, it is not safe to drive with a failing fuel pump. A weak fuel supply can cause your engine to stall without warning, which is extremely dangerous in traffic or on the highway . You may also experience sudden power loss, hesitation, or surging, making your vehicle unpredictable to handle. Continuing to drive can also damage other expensive parts, such as the catalytic converter, because unburned fuel can enter the exhaust system . If you suspect a fuel pump problem, drive the car to a safe spot and have it towed to a shop for repairs .

How Much Does a 2017 Kia Forte Fuel Pump Replacement Cost?

The cost of replacing the fuel pump on a 2017 Kia Forte varies depending on where you live, whether you use a dealership or an independent shop, and the quality of the replacement part. Here is a breakdown:

Professional Shop Estimate

  • Total Cost: $1,286 to $1,439
  • Labor: $135 to $198
  • Parts: Around $1,241 for the pump assembly
  • Note: This range does not include taxes, fees, or location-specific pricing .

OEM Parts Pricing
The genuine Kia fuel pump assembly (part number 31120-F3500) for the 2019-2024 models has a retail price of $674.48, though you can often find it discounted to around $448.40 . For the 2017 model, the part number may differ, but expect similar pricing for OEM parts.

Aftermarket Parts Pricing
You can save money by purchasing an aftermarket fuel pump assembly. For example, a compatible A-Premium fuel pump assembly for the 2017-2018 Kia Forte 2.0L costs around $125.99 new . Other aftermarket options range from $31.99 for a basic electric pump to $767.99 for a premium module assembly .

How to Diagnose a Fuel Pump Problem

Before replacing the pump, it is important to confirm that it is actually the cause of your symptoms. Here is what a mechanic will typically do:

  1. Check Fuel Pressure: The mechanic will attach a fuel pressure gauge to the fuel rail and check the pressure while the engine is running. Low pressure indicates a failing pump or a clogged filter .
  2. Inspect the Electrical Circuit: If the pump is not getting enough voltage or has a bad connection, the circuit may need repair .
  3. Check the Fuel Filter: A clogged fuel filter can mimic the symptoms of a bad fuel pump, so the mechanic will inspect it first .
  4. Listen for Noise: A whining sound from the fuel tank is a strong sign of pump failure.

DIY Fuel Pump Replacement: What You Need to Know

Replacing the fuel pump on a 2017 Kia Forte is a challenging job, but it is possible for an experienced DIYer. Here is a general overview of the steps:

Tools and Parts You Will Need:

  • New fuel pump assembly (OEM or aftermarket)
  • Basic hand tools (socket set, screwdrivers, pliers)
  • Fuel line disconnect tool
  • Safety glasses and gloves
  • Fire extinguisher (fuel is highly flammable)
  • Jack and jack stands

General Steps:

  1. Relieve Fuel Pressure: Locate the fuel pump fuse in the fuse box and remove it. Start the engine and let it run until it stalls. This relieves pressure in the fuel system.
  2. Disconnect the Battery: Always disconnect the negative battery terminal before working on the fuel system.
  3. Access the Fuel Pump: On most Kia Forte models, the fuel pump is accessed through the trunk. Remove the carpet lining in the trunk to expose the access panel. Remove the screws holding the panel in place.
  4. Disconnect Electrical and Fuel Lines: Carefully disconnect the wiring harness and fuel lines from the pump assembly. Use the fuel line disconnect tool to avoid damaging the lines.
  5. Remove the Old Pump: Unscrew the locking ring that holds the pump in place. Lift the pump assembly out of the tank. Be careful not to bend the fuel level sending unit arm.
  6. Install the New Pump: Transfer the fuel level sending unit and any other components from the old pump to the new one if they are not included. Lower the new pump into the tank and secure it with the locking ring.
  7. Reconnect Everything: Connect the fuel lines, electrical connector, and battery. Replace the access panel and trunk carpet.
  8. Test the System: Turn the key to the "ON" position (without starting the engine) a few times to prime the fuel system. Check for leaks before starting the engine.

Important: Consult the vehicle's service manual for specific torque specifications and procedures for your exact model .

How Often Should You Replace the Fuel Pump?

Fuel pumps do not have a specific replacement interval . Replacement becomes more common as the mileage on the car increases. However, you can extend the life of your fuel pump by avoiding these habits:

  • Running the fuel tank low repeatedly: This causes the pump to suck up sediment from the bottom of the tank, which can clog the filter and damage the pump .
  • Driving with a clogged fuel filter: A dirty filter puts additional strain on the pump .
  • Using low-quality fuel: Contaminated fuel can damage the pump.

Conclusion: What to Do Next

If your 2017 Kia Forte is showing symptoms of a bad fuel pump, do not ignore them. The cost of replacement is significant, but it is far less expensive than the damage a stalled engine can cause. Start by getting a proper diagnosis from a mechanic who can test the fuel pressure and check the electrical system. Once you confirm the pump is the issue, you have two options: pay a professional $1,286 to $1,439 for the repair, or tackle the job yourself using an aftermarket part to save hundreds of dollars.
