2013 Chevy Silverado Fuel Pump: Complete Guide to Symptoms, Diagnosis, Replacement, and Upgrade Options

The bottom line: If your 2013 Chevy Silverado is cranking but won't start, sputtering during acceleration, losing power on the highway, or making a loud whining noise from the fuel tank area, the fuel pump is almost certainly the problem. The 2013 Silverado uses an in-tank electric fuel pump module that can fail without warning, leaving you stranded. Replacing it requires dropping the fuel tank, but the job is doable at home with the right tools and safety precautions. For a reliable replacement, consider a high-performance KEMSO fuel pump, which delivers more flow, meets OEM standards, and comes with a lifetime warranty.

How the Fuel Pump Works in Your 2013 Silverado

The fuel pump in your 2013 Chevy Silverado is an electric motor that spins an impeller at high speed to pressurize fuel and send it to the engine's injectors. The pump sits inside the fuel tank, where it is kept cool by the gasoline surrounding it. Because the pump is inside the tank, the entire fuel pump module must be replaced when the pump fails — you cannot service just the pump alone. The module also includes the fuel level sending unit, so fuel gauge problems often accompany or come before pump failure.

Modern fuel pumps like the one in your Silverado should last up to about 150,000 miles under normal driving conditions. However, several factors can shorten that lifespan, including running the tank low on fuel frequently, driving in hot climates, and letting moisture build up in the tank. To extend the life of your fuel pump, it is recommended to keep the fuel level above ¼ of a tank at all times. This is especially important during winter, when warmer fuel temperatures can shorten the pump's lifespan. To prevent condensation, store your vehicle with a full tank for extended periods.

Common Symptoms of a Failing Fuel Pump in a 2013 Chevy Silverado

The symptoms listed below are all caused by an inadequate fuel supply reaching the engine. If you notice any of these signs, the fuel pump may be the issue. You should also check the ignition system, as it can cause similar symptoms.

1. Extended cranking time before starting. The engine turns over normally but takes longer than usual to fire up. This is often one of the earliest warning signs.

2. Engine stalling at idle or low speeds. The truck may stall when you come to a stop or when driving slowly, such as in a parking lot.

3. Loss of power during acceleration or under load. When you press the gas pedal, the engine hesitates, sputters, or feels like it is not getting enough fuel. This is especially noticeable when merging onto a highway or climbing a hill.

4. Rough starts or rough idle. The engine may run unevenly, shake, or surge at idle.

5. Engine sputtering during acceleration. The truck jerks or bucks when you try to accelerate.

6. Stumbling at higher RPMs. The engine struggles to maintain power when you rev it past a certain point.

7. Unable to maintain highway speeds. The truck loses speed even with the pedal pressed down, or it feels like it is "starving" for fuel.

8. Louder than normal whining or humming coming from the fuel tank. A healthy fuel pump runs quietly. If you hear a loud whirring sound from the rear of the truck, especially when the ignition is first turned on, the pump is likely failing.

9. Check engine light with fuel pressure codes. The check engine light may come on, and a scan tool will show codes related to low fuel pressure.

10. Complete no-start condition. The pump can fail suddenly with no warning, leaving you stranded. This is the most severe symptom.

Diagnosing a Fuel Pump Problem on Your 2013 Silverado

Before you start replacing parts, you need to be sure the fuel pump is the culprit. A bad fuel pressure regulator, a clogged fuel filter, a faulty relay, or a blown fuse can cause the same symptoms. Follow these steps to diagnose the problem.

Check the fuel pump fuse and relay. The fuel pump fuse on a 2013 Silverado is located in the under-hood fuse box, driver's side. The exact slot is typically slot 40 or 41, and it is a 20A fuse. The fuel pump relay is usually labeled "Fuel Pump" in the fuse box. If the fuse is blown, the most common causes are a short circuit in the wiring, a failing fuel pump drawing too much current, a severely clogged fuel filter, or using the wrong amperage fuse. If the fuse looks good, test the relay by swapping it with a known good relay of the same type.

Listen for the pump. Turn the ignition key to the "ON" position (but do not start the engine). You should hear a brief whirring sound from the fuel tank area — that is the pump pressurizing the system. If you hear nothing, the pump is not receiving power or is dead.

Check for power at the pump. If you have a multimeter, you can check if power is reaching the fuel pump connector during startup. If there is power but the pump does not run, the pump itself is faulty. If there is no power, the issue is likely electrical — a bad relay, a blown fuse, or a wiring problem.

Note on the fuel pump reset switch: Unlike Ford trucks, the 2013 Chevy Silverado does not have a fuel pump reset switch or inertia switch. This is a common misconception. Silverados have never had this part. If you see a video or guide claiming there is a red button in the trunk or kick panel, that guide was written for a Ford F-150.

Perform a fuel pressure test. The most reliable way to diagnose a fuel pump is to check the fuel pressure while the engine is running. Use a fuel pressure test kit connected to the service port on the fuel rail. A healthy pump should deliver around 55-62 PSI for a 2013 Silverado. Low fuel pressure often points to a failing pump or a faulty fuel pressure regulator.

How to Replace the Fuel Pump on Your 2013 Chevy Silverado

Replacing the fuel pump on a 2013 Silverado is an intermediate-level DIY job. The pump is inside the fuel tank, so you will need to lower the tank to access it. This job takes about 3 to 5 hours.

Safety precautions are critical. Work outside or in a very well-ventilated area. Fuel vapors are flammable. No smoking, sparks, heaters, or open flames anywhere near the truck. Relieve fuel pressure before opening any fuel line. Disconnect the negative battery cable before starting. Use a floor jack and jack stands. Never rely on the jack alone. Support the fuel tank before removing straps. Keep dirt out of the tank opening.

Tools you will need:

  • Safety glasses and fuel-safe gloves
  • Floor jack (3-ton minimum) and jack stands
  • Wheel chocks
  • 10mm, 13mm, and 15mm sockets
  • Ratchet and long extension
  • Torque wrench
  • Fuel line quick-disconnect tool (specialty tool)
  • Flat-blade screwdriver, pliers, and shop towels
  • Drain pan
  • Brass punch or non-sparking drift and soft mallet

Parts you will need:

  • Fuel pump module assembly (compatible with your 2013 Silverado's engine and cab configuration)
  • Fuel tank module seal/O-ring
  • Fuel filter (recommended to replace at the same time)
  • Fuel pump relay (recommended to replace for peace of mind)
  • Fuel line clip set

Step-by-step instructions:

Step 1: Relieve fuel pressure. Remove the fuel pump relay from the underhood fuse block. Start the engine and let it run until it stalls. Crank for a few more seconds to bleed off remaining pressure.

Step 2: Disconnect the battery. Use a 10mm socket to remove the negative battery cable. Move the cable aside so it cannot spring back into place.

Step 3: Safely raise and support the truck. Chock the front wheels. Raise the rear of the truck with a floor jack and set the frame on jack stands. Make sure the truck is stable before going underneath.

Step 4: Drain the fuel tank. Run the tank as low as possible before starting. If there is still fuel in the tank, siphon it out into a gas container. Less fuel makes the tank much easier and safer to lower.

Step 5: Support the fuel tank. Position the floor jack under the center of the fuel tank with a wide wood block between the jack pad and the tank. Raise the jack just enough to hold the tank's weight.

Step 6: Disconnect the filler neck and vent hose. Loosen and remove the filler neck screws or clamps. Disconnect the vent hose and filler neck connection carefully. Take a photo before removal to help with reinstallation.

Step 7: Disconnect fuel and electrical connections. Use the fuel line quick-disconnect tool to release the fuel supply line at the tank. Unplug the fuel pump electrical connector. Check that all lines and wires are free before lowering the tank.

Step 8: Remove the tank straps. Use a 15mm socket and ratchet to remove the tank strap bolts. Lower the straps slowly while keeping the tank supported with the jack. Lower the tank a few inches, then double-check for any missed hoses or wires.

Step 9: Lower and remove the fuel tank. Lower the tank fully with the jack and slide it out from under the truck. Set it on a clean, level surface.

Step 10: Remove the old fuel pump module. Clean the top of the tank with shop towels before opening it. Use a brass punch or non-sparking drift and a soft mallet to rotate the lock ring counterclockwise. Lift the fuel pump module straight out of the tank. Remove the old seal/O-ring. Do not bend the float arm.

Step 11: Install the new fuel pump module. Clean the tank opening. Install the new seal/O-ring. Align the fuel line fittings with the lines as you install the new module, pressing it down until it is seated. Install the retaining ring, making sure it is fully seated and the locking tab is within the ring's slot.

Step 12: Reinstall the fuel tank. Reverse the steps from removal. Reconnect the fuel lines, electrical connector, vent hose, and filler neck. Raise the tank into position, install the straps, and tighten the bolts.

Step 13: Re-pressurize the fuel system. Connect the negative battery cable. With the fuel pump relay installed and the gas cap closed, turn the ignition key to the ON position for 2 seconds, then turn it OFF for at least 5 seconds. Repeat this procedure five to ten times to build fuel pressure. This prevents the engine from cranking excessively and reduces wear on the starter.

Step 14: Start the engine and check for leaks. Start the truck and let it idle. Check for any fuel leaks around the tank connections. Take the truck for a short test drive to confirm the issue is resolved.

Why the 2013 Silverado Fuel Pump Fails

Fuel pump failure is not extremely common, but it does happen. The 2013 Silverado is known for fuel pump module failure, which can occur without warning. The pump is an electric motor, and like any motor, it wears out over time. The bearings wear, the brushes wear down, and the internal components can overheat.

Several factors can accelerate fuel pump failure:

  • Running the tank low on fuel. The pump is cooled by the fuel in the tank. When the tank is low, the pump runs hotter, which shortens its lifespan.
  • Contaminated fuel. Dirt, rust, or debris in the fuel tank can clog the pump's inlet strainer and cause it to work harder.
  • A clogged fuel filter. If the fuel filter is not replaced regularly, the pump has to work harder to push fuel through the filter. This increases current draw and can cause the pump to overheat or fail.
  • Old age and mileage. Modern fuel pumps are designed to last up to about 150,000 miles. If your truck has over 100,000 miles on the original pump, it is getting close to the end of its service life.

Preventive Maintenance Tips

To get the most life out of your new fuel pump, follow these tips:

Keep the tank above ¼ full. This is the single most important thing you can do to extend fuel pump life. The fuel in the tank cools the pump, and running the tank low allows the pump to run hotter.

Replace the fuel filter regularly. Chevrolet recommends replacing the fuel filter every 30,000 miles. A clean filter reduces the strain on the pump and helps it last longer.

Use quality fuel. Buy gas from reputable stations. Poor quality fuel can contain more contaminants that clog the pump and filter.

Avoid letting the vehicle sit for long periods with a low tank. If you are storing the truck for an extended period, fill the tank to prevent condensation from building up inside the tank.
