The 2020 Hyundai Venue may experience fuel pump issues causing engine stalling, difficulty starting, or a strong gas smell. Symptoms include sputtering, loss of power while driving, the check engine light turning on, or the engine shutting off completely. Potential causes are a faulty high-pressure fuel pump, clogged fuel filter, leaking fuel lines, or excessive fuel contamination in the oil. To fix the problem, the fuel system should be inspected for leaks and the pump, filter, and any damaged components replaced.
Symptoms
- Difficulty starting the engine or engine not starting at all
- Engine stalling or shutting off while driving
- Loss of power or hesitation during acceleration
- Sputtering, backfiring or rough running engine
- Check engine light turning on
- Excessive fuel consumption or poor fuel efficiency
- Strong smell of gasoline, especially after filling up the tank
Potential Causes
- Clogged fuel filter – Over time, the fuel filter can become clogged with debris, restricting fuel flow to the engine and causing the fuel pump to work harder than it should.
- Faulty fuel pressure regulator – If the fuel pressure regulator is faulty, it can cause the fuel pump to work harder than normal, leading to premature failure.
- Damaged fuel pump, fuel lines, or gas tank – Any damage to the fuel pump itself, the hoses between the filler neck and tank, or the gas tank can restrict fuel flow.
- Blockages in the vapor recovery system – In newer vehicles with onboard refueling vapor recovery (ORVR), restrictions anywhere in the system from the charcoal canister to vent valves can prevent proper venting and make it difficult to fill the tank.
- Contaminated fuel – Using low quality or contaminated gasoline can potentially damage the fuel pump over time.
- Excessive fuel in the engine oil – Some Hyundai and Kia turbo petrol engines have experienced fuel pump failures due to fuel diluting and contaminating the engine oil.
How to Diagnose fuel pump Issues in Your 2020 Hyundai Venue?
Here are the key steps to diagnose potential fuel pump problems in your 2020 Hyundai Venue:
1.Check for common symptoms
- Difficulty starting the engine or engine not starting at all
- Engine stalling or shutting off while driving
- Loss of power or hesitation during acceleration
- Sputtering, backfiring or rough running engine
- Check engine light turning on
2. Listen for the fuel pump
Remove the gas cap and have someone turn the ignition key to the “on” position without cranking the engine. You should hear a whirring noise from the fuel pump running for about 2 seconds. If you don’t hear any noise, it indicates the pump is not turning on.
3. Check the fuel pump relay and fuse
- Locate the fuel pump relay and fuse in the engine bay fuse box.
- Visually inspect them for any signs of damage or corrosion.
- Use a multimeter to test for continuity of the relay and fuse.
4. Test the fuel pressure
- Connect a fuel pressure gauge to the Schrader valve on the fuel rail.
- Turn the ignition key to prime the pump and check the pressure reading.
- Compare the reading to the manufacturer’s specified pressure range.
- If pressure is lower than specified, it points to a weak fuel pump.
5. Access and inspect the fuel pump
- The pump is usually located under the rear seats or in the trunk area under an access panel.
- Check the electrical connector and wiring for any loose connections or damage.
- If the pump still runs, check for a clogged fuel filter or leaking fuel pressure regulator.
How to Fix 2020 Hyundai Venue fuel pump Problems– Step by step
Here is a step-by-step guide on how to fix fuel pump problems in your 2020 Hyundai Venue:
Step 1: Diagnose the issue.
- Check for common symptoms like difficulty starting, engine stalling, loss of power, sputtering, or the check engine light.
- Listen for the fuel pump noise when turning the key to “on” without cranking. If you don’t hear a whirring sound, the pump may not be turning on.
- Test the fuel pressure using a gauge connected to the fuel rail. Compare the reading to manufacturer specifications.
Step 2: Check the fuel pump relay and fuse.
- Locate the fuel pump relay and fuse in the engine bay fuse box.
- Visually inspect them for damage or corrosion.
- Use a multimeter to test continuity of the relay and fuse.
Step 3: Access the fuel pump.
- Disconnect the negative battery cable for safety.
- Remove the rear seat or access panel to reach the fuel pump module.
- Disconnect the electrical connector and fuel lines from the pump.
Step 4: Replace the fuel pump.
- Unbolt and remove the old fuel pump from the fuel tank.
- Clean the mounting surface and install the new fuel pump securely.
- Reconnect the wiring and fuel lines to the new pump.
Step 5: Replace the fuel filter.
- The in-tank fuel filter should be replaced along with the pump.
- Locate the filter attached to the fuel pump module.
- Disconnect the filter from the fuel lines and replace it with a new one.
Step 6: Reinstall components.
- Reinstall the fuel pump module into the tank.
- Reconnect the negative battery cable.
- Turn the ignition key to prime the system and check for any leaks.
Step 7: Test the repair.
- Start the engine and let it idle.
- Check if previous symptoms like hard starting or stalling have been resolved.
- Take the car for a test drive and verify it is running smoothly without power loss.
Repairing 2020 Hyundai Venue fuel pump Problems: DIY or Professional Help?
Repairing fuel pump problems in a 2020 Hyundai Venue can be done as a DIY project if you have some mechanical skills and are comfortable working on your vehicle. However, it’s important to carefully consider whether to attempt the repair yourself or seek professional help.

Preventing Future fuel pump Problems in 2020 Hyundai Venue
Here are some key steps to help prevent future fuel pump problems in your 2020 Hyundai Venue:
Regularly maintain your vehicle
- Follow the recommended maintenance schedule in your owner’s manual.
- Regular servicing can help ensure the fuel system’s longevity and performance.
Use high-quality fuel
- Fill up with top tier detergent gasoline from reputable gas stations.
- Avoid using fuel with contaminants that can damage the fuel pump and clog the fuel filter over time.
Keep the fuel tank at least 1/4 full
- Running the vehicle frequently on a nearly empty tank can cause the fuel pump to overheat.
- Keeping the tank at least 1/4 full ensures the pump stays submerged and cooled by the fuel.
Be attentive to early warning signs
- Watch for symptoms like sputtering, power loss, hard starting, or unusual noises.
- Catching potential issues early can prevent more extensive damage to the fuel system.
Have any drivability issues promptly diagnosed
- If you experience problems like the engine shutting off unexpectedly, get it checked by your Hyundai dealer.
- Insist on them documenting the issue and taking steps to diagnose it, even if no check engine light is on.
Consider turning off the Idle Stop & Go (ISG) system
- If your Venue is equipped with ISG, it automatically shuts the engine off at stops to save fuel.
- Frequent restarting can put additional strain on the fuel pump, so disabling ISG may help extend its life.
Replace the fuel filter along with the pump
- If the fuel pump needs to be replaced, install a new fuel filter at the same time.
- A clean filter puts less strain on the pump and maintains proper fuel flow.
