Fuel Pump for 2016 Kia Soul: The Complete DIY Replacement Guide
Symptoms of a Failing Fuel Pump in Your 2016 Kia Soul
Common signs that indicate your fuel pump needs replacement include :
- Engine sputtering or surging at high speeds – The engine hesitates or jerks when you maintain a steady speed on the highway.
- Loss of power when accelerating, especially uphill – You press the gas pedal but the car struggles to gain speed.
- Difficulty starting the engine – The engine cranks longer than normal before firing up, or it doesn't start at all.
- The engine stalls, particularly when hot – The car shuts off unexpectedly after driving for a while.
- A whining noise coming from the fuel tank area – The pump makes a loud, high-pitched sound that wasn't there before.
- The check engine light comes on – Fuel system related diagnostic codes appear on your scan tool.
If you experience any of these symptoms, test the fuel pressure with a gauge before replacing the pump to confirm whether the pump is delivering the correct pressure to the engine . However, if your Kia Soul has more than 100,000 miles, preventive replacement is often a wise choice to avoid being stranded on the road .
Location of the Fuel Pump in a 2016 Kia Soul
The fuel pump in a 2016 Kia Soul is located inside the fuel tank. Access is gained through a maintenance panel in the rear cargo floor, usually under the carpeting or a removable floor cover . For most 2016 Souls, the pump module sits inside the tank as part of the fuel sender assembly. There is no exterior or under-vehicle access panel; you reach it by opening the trunk floor panel or folding down the rear seats to reach the panel, depending on your trim and region .
The in-tank design reduces vapor leaks, aids cooling, and helps maintain stable fuel pressure . In many Souls, you will find a round or rectangular plastic cover in the right-side portion of the rear cargo floor under a carpet or floor mat. Remove the cover to expose the pump module fastened with screws or a retention ring . Always confirm with your owner's manual or a repair guide for your exact vehicle, since some configurations place the access panel behind the rear seat or under a floor shelf .
Tools and Parts You Will Need
Before you start, gather the following tools and replacement parts:
Tools:
- Fuel pump lock ring wrench (specialty tool) or a non-sparking brass punch and small hammer
- Trim removal tool set
- Phillips screwdriver #2 or 10mm socket
- 10mm socket for the battery terminal
- Shop towels or rags
- Catch pan for any spilled fuel
- Plastic scraper
- Safety glasses and gloves
Parts:
- New fuel pump module assembly (compatible with 2016 Kia Soul)
- New tank seal (O-ring/gasket) – always replace this to prevent leaks
- New fuel filter (if not included in the pump module)
Step-by-Step Fuel Pump Replacement Procedure
Step 1: Safety First
Park the car on a level surface and disconnect the negative battery terminal to prevent sparks . Relieve fuel system pressure by removing the fuel pump fuse or relay, then starting the engine until it stalls. Turn off the ignition .
Step 2: Access the Fuel Pump
Remove the rear seat cushion. Use a trim removal tool and a 10mm socket as needed . Locate and remove the fuel pump service cover. On most 2016 Souls, this is a round or rectangular plastic cover in the right-side portion of the rear cargo floor . Remove the cover fasteners using a Phillips screwdriver #2 or 10mm socket .
Step 3: Disconnect Electrical and Fuel Lines
Disconnect the fuel pump connector and the fuel tank pressure sensor connector . Disconnect the fuel feed tube quick connector and the vapor tube quick-connector . Push each fuel line connector until it releases. Be prepared for a small amount of fuel spillage.
Step 4: Remove the Retaining Ring
Use a fuel pump lock ring wrench to turn the ring counterclockwise . If access is tight, use a non-sparking brass punch and small hammer to tap the ring counterclockwise, working evenly around the ring . Remove the ring and set it aside in a clean place.
Step 5: Remove the Old Fuel Pump Module
Lift the module slowly straight up. Angle it as needed to clear the float arm, which is the plastic arm that measures fuel level . Let fuel drain from the module into the tank for a few seconds. Place the module into the catch pan .
Step 6: Replace the Tank Seal
Remove the old seal from the tank opening using a plastic scraper. Wipe the sealing surface clean with shop towels. Install the new fuel pump module tank seal flat and fully seated, with no twists .
Step 7: Install the New Fuel Pump Module
Carefully lower the new fuel pump module assembly into the tank, guiding the float arm to avoid bending it. Align the module tabs or index marks with the tank. It should sit flat and flush .
Step 8: Reinstall and Tighten the Lock Ring
Install the ring by hand first to avoid cross-threading. Tighten using the fuel pump lock ring wrench until fully seated against its stop and aligned to your reference mark. Most Soul lock rings do not use a published torque value; tighten firmly to full seat with the correct wrench. Do not overtighten, as this can warp the sealing surface or crack the plastic module .
Step 9: Reconnect Fuel Lines and Electrical Connector
Push each fuel line on until it clicks and will not pull back off by hand. Plug in the electrical connector until the lock clicks. Wipe any spilled fuel using shop towels .
Step 10: Reinstall the Service Cover and Rear Seat
Reinstall the service cover fasteners using a Phillips screwdriver #2 or 10mm socket. Reinstall the rear seat cushion using the trim removal tool set and 10mm socket as applicable .
Step 11: Reconnect the Battery
Reconnect the negative battery terminal using a 10mm socket .
After Repair: Testing and Verification
Prime the system by turning the key to the ON position for 5 seconds, then OFF for 5 seconds. Repeat this cycle three times. Do not crank the engine during this step .
Check for leaks at the pump top and fuel line connections. Look and smell for any fuel odor .
Start the engine and let it idle for 2 to 3 minutes. Recheck for leaks .
Take the car on a 5 to 10 minute road test, then perform one final leak check .
If a fuel-related warning light remains on, a scan may be needed. Often it clears after a few drive cycles if the repair is correct .
Common Mistakes to Avoid
Not marking the fuel lines before disconnecting them: If you do not mark them, you may reconnect them incorrectly, which can cause the engine to run poorly or not start at all .
Skipping the new O-ring: The O-ring that seals the fuel pump assembly to the tank is a wear item. Always replace it with a new one to prevent leaks and fuel odor inside the cabin .
Overtightening the retaining ring: This can warp the sealing surface or crack the plastic module. Use a torque wrench to tighten to the manufacturer's specification .
Forgetting to relieve fuel pressure: Always release the residual pressure in the fuel line before starting any work .
