2017-2020 Chevrolet Spark Fuel Pump: Stalling, No-Start Symptoms, and Replacement

Symptoms of a Failing Fuel Pump

A failing fuel pump in a Chevrolet Spark doesn't usually quit without warning. It often gives signs that the fuel supply is becoming weak or inconsistent. Ignoring these symptoms can leave you stranded.

• Engine Cranks but Won't Start: This is the most definitive sign of a completely failed fuel pump. The engine will turn over but never catch, because it's not receiving any fuel. You can often confirm this by turning the key to the 'On' position (without starting) and listening for a faint humming or whining noise from the rear seat area. If you hear nothing, the pump is likely dead.
• Engine Sputtering or Hesitation: If the car sputters or hesitates when you accelerate, the pump may be struggling to provide the extra fuel the engine needs. This is often most noticeable at highway speeds or when going uphill.
• Stalling at Idle or Low Speeds: Some owners report the engine stalling when stopped at a light or moving at low speeds. This can happen if the pump overheats or can't maintain consistent pressure.
• Loss of Power: The car may feel sluggish and lack its normal acceleration. This happens when the pump can't deliver enough fuel volume under load.
• Whining Noise from the Fuel Tank: A loud whining or buzzing sound from the rear of the car is a classic sign of a fuel pump motor working too hard, often because it's failing or the fuel filter is clogged.
• Check Engine Light with Fuel-Related Codes: A failing pump can trigger the Check Engine Light. Common codes include:
  • P0087 - Fuel Rail/System Pressure - Too Low.
  • P0089 - Fuel Pressure Regulator Performance.

Known Issues, TSBs, and Recalls

As of early 2026, there are no active recalls for the fuel pump on the 2017-2020 Chevrolet Spark. However, there are known issues and a technical service bulletin (TSB) to be aware of.

Technical Service Bulletin (TSB) PIP5596A

This bulletin warns technicians that when a specific fuel line jumper hose is removed during service, it must be reinstalled correctly. Improper installation can lead to a no-pressure or low-pressure situation, mimicking the symptoms of a failed pump. If you've recently had fuel system work done and are now experiencing problems, this is a possible cause.

Common Failure Patterns

Forum discussions among Spark owners suggest that premature fuel pump failure is not uncommon. Some owners have experienced stalling and no-start conditions that were resolved with a new pump. Another potential weak point is the electrical connector on top of the fuel pump assembly, which can become corroded and cause an intermittent or complete loss of power to the pump.

Diagnosing a Bad Fuel Pump

Before replacing the pump, it's important to confirm it's the actual problem.

1. Listen for the Pump: Have a helper turn the ignition key to the 'On' position (don't start the engine) while you listen near the rear seat. You should hear a 2-3 second hum as the pump primes the system. No sound points to a dead pump 🎬 Watch: A quick guide on testing a fuel pump that won't start. or an electrical issue.
2. Check Fuses and Relays: Consult your owner's manual to locate the fuel pump fuse and relay. A blown fuse or faulty relay will cut power to the pump and is a much cheaper fix. A repeatedly blowing fuse suggests the pump is drawing too much current and is about to fail.
3. Perform a Fuel Pressure Test: This is the most definitive test. While the Spark may not have a dedicated test port on the fuel rail, a technician can connect a pressure gauge in-line. 🎬 Watch: How to perform a fuel pressure test on a Spark. The test involves checking the pressure with the key on (engine off) and again at idle. A pressure reading that is below specification or drops off quickly indicates a weak pump or a clogged filter.

Buying a Used Fuel Pump for a 2017-2020 Spark

A quality, low-mileage used OEM fuel pump can be a smart, reliable alternative to expensive new parts or lower-quality aftermarket units. Here’s what to check before you buy:

• Verify the Part Number: The most common OEM part number is 19367492. You may also see older, superseded numbers like 13512677 or 13515298. Ensure the part you're buying is listed as a direct fit for the 2017-2020 Spark.
• Inspect the Electrical Connector: This is the most critical inspection point. Look closely at the electrical pins and the plastic surrounding them on top of the pump assembly. There should be no signs of melting, browning, black marks, or green/white corrosion. Any heat damage indicates a poor connection that will lead to failure. Do not buy a pump with a damaged connector.
• Check for Physical Damage: Inspect the white plastic housing of the pump module for any cracks, especially around the mounting points and hose connections. A cracked housing can cause fuel leaks.
• Examine the Fuel Level Float: Ensure the metal arm for the fuel level sender is present and not bent or damaged. The plastic float at the end should be intact. A damaged float arm will cause your fuel gauge to read incorrectly.
• Ask for Mileage: If possible, get the mileage from the donor vehicle. A pump from a car with 50,000 miles is a much better bet than one from a car with 150,000 miles. Fuel pumps are wear items, so lower mileage is always better.

Cost Comparison for Chevrolet Spark Fuel Pump Replacement

Prices can vary significantly based on the part source and your location. The high estimates from some sources appear to be outliers, as the part itself is not exceptionally expensive.

Replacement Overview & Difficulty

Replacing the fuel pump on a 2017-2020 Spark is a moderately difficult job that a skilled DIYer can perform.

• Difficulty: 3 out of 5
• Time: 1.5 - 2.5 hours
• Key Steps: The fuel pump is accessed by removing the lower cushion of the rear seat. An access panel is removed to expose the top of the fuel tank. The fuel lines and electrical connector are disconnected. A large plastic lock ring holds the pump in place and must be unscrewed (this may require a special tool or careful use of a hammer and punch). 🎬 See this step-by-step guide for installing the new pump assembly. The old pump assembly is lifted out, and the new one is installed.
