2001 Chevy Silverado Fuel Pump Fuse Location: A Complete Guide

If you own a 2001 Chevy Silverado and your truck won’t start, or the engine cranks but refuses to fire, the fuel pump fuse is one of the first things you should check. The fuel pump fuse on a 2001 Chevy Silverado is located in the underhood fuse block, inside the engine compartment on the driver’s side, near the brake master cylinder. It is a 20-amp fuse, typically labeled as “FUEL PUMP” or “FUEL PUMP/INJ” in the fuse box diagram. This simple component can save you from a costly tow truck bill or an unnecessary trip to the mechanic if it’s blown. Let’s walk through everything you need to know about locating, testing, and replacing this fuse, plus what to do if the fuse is good but the pump still isn’t working.

Understanding the Fuel Pump Fuse and Its Role

The fuel pump fuse is a small but critical safety device. It protects the fuel pump’s electrical circuit from excessive current. If there is a short circuit or a damaged wire, the fuse will blow (melt its internal link) to prevent a fire or damage to the wiring and the pump itself. On a 2001 Silverado, the fuel pump relay and fuse work together. The relay is an electrical switch that turns on the pump when the key is turned to the “ON” position, while the fuse provides overcurrent protection. If the fuse is blown, the pump will not receive power, and the engine will not start.

Step-by-Step: How to Find the Fuel Pump Fuse on a 2001 Chevy Silverado

1. Locate the Underhood Fuse Block

Open the hood of your Silverado. Look along the driver’s side of the engine compartment, near the firewall and the brake master cylinder. You will see a black plastic box with a cover. This is the main fuse block for your truck.

2. Remove the Fuse Box Cover

Press the tabs on the sides of the cover and lift it off. On the underside of the cover, there is a diagram that labels the fuses and relays. If the diagram is missing or faded, refer to the owner’s manual or the diagrams we have linked below.

3. Identify the Fuel Pump Fuse

On the 2001 Silverado (both 1500 and 2500 models), the fuel pump fuse is a 20-amp fuse. It is usually positioned in a specific slot. Based on the fuse box diagrams from multiple sources, the fuel pump fuse is often located in a slot that is separate from the main fuses, but it is clearly labeled. Common labels include “FUEL PUMP,” “FUEL,” or “FUEL PUMP/INJ.” If you have a 2001 Silverado 1500, the fuse is typically in the underhood fuse box, slot 10 or 15, depending on your specific build date. For the 2500 models, the layout is similar but check the diagram on your specific cover.

4. Check the Fuse

Pull the fuse out using a fuse puller tool (usually stored inside the fuse box or in the glove compartment). Look at the metal strip inside the fuse. If it is broken or melted, the fuse is blown. If you see a brown or black mark, the fuse has failed.

What to Do If the Fuel Pump Fuse Is Blown

If you find a blown fuse, do not just replace it and assume the problem is solved. A blown fuse is a symptom of an underlying issue. Here’s what to do:

  • Replace the fuse with the same amperage (20-amp). Never use a higher amperage fuse, as that can cause wiring to overheat and start a fire.
  • Check for a short circuit. If the new fuse blows immediately, there is likely a short in the fuel pump wiring, the fuel pump itself, or the connector. Inspect the wiring harness near the fuel tank on the frame rail for any chafed or exposed wires. Also, check the connector at the fuel pump assembly (located inside the fuel tank, accessible from the top of the tank under the truck bed).
  • Test the fuel pump relay. The fuel pump relay is also located in the underhood fuse box. It is typically a larger black or gray square relay. You can swap it with a known good relay (like the A/C compressor relay or horn relay, which are usually the same type) to see if the pump starts working.

If the Fuse Is Good but the Pump Still Doesn’t Work

Don’t stop at the fuse. A good fuse does not guarantee the fuel pump is getting power. Here are the next steps:

  • Check the fuel pump relay. As mentioned, the relay can fail without blowing the fuse. Listen for a click when you turn the key to the “ON” position. If no click, the relay or its control circuit is suspect.
  • Inspect the fuel pump reset switch. Some 2001 Silverado models have an inertia fuel pump shutoff switch (also called a fuel pump reset switch). This is a safety device that cuts power to the fuel pump in the event of a collision. It is located on the passenger side of the truck, behind the kick panel or under the glove box, on the firewall. Look for a small rectangular box with a red button. Press the button to reset it. If the button is popped up, pressing it down may restore power to the pump.
  • Test the fuel pump voltage. Using a multimeter, check for 12 volts at the fuel pump connector (located on the top of the fuel tank, or under the truck near the tank). If you have voltage and the pump is not running, the pump itself is likely dead.
  • Listen for the pump. When you turn the key to the “ON” position (without starting the engine), you should hear a brief hum from the fuel tank for 2-3 seconds. If you hear nothing, the pump is not receiving power or is dead.

Common Symptoms of a Bad Fuel Pump Fuse or Relay

Before you even look at the fuse, your truck will give you clues. Watch for these signs:

  • Engine cranks but does not start. This is the most common symptom. The starter motor turns the engine over, but no fuel is delivered.
  • No engine noise from the fuel tank. As mentioned, when you turn the key to the “ON” position, you should hear the fuel pump prime for a few seconds. If you hear nothing, either the fuse, relay, or pump is faulty.
  • Stalling or hesitation. If the fuse is partially blown or the relay is intermittent, the engine may stall while driving, especially under load or on uphill grades.
  • Check Engine Light. A faulty fuel pump circuit can trigger a check engine light, often with codes related to fuel system pressure or electrical issues.

Where to Buy a Reliable Replacement Fuel Pump

If you have confirmed that the fuse is good, the relay is working, and the wiring is intact, but the pump still doesn’t run, the fuel pump itself is likely the culprit. Replacing the fuel pump on a 2001 Chevy Silverado is a significant job (the fuel tank must be removed or dropped), so you want to install a high-quality part that will last.

Additional Tips for a Successful Fuel Pump Replacement

  • Safety First: Always disconnect the battery negative terminal before working on any fuel system components. Gasoline is highly flammable.
  • Relieve Fuel Pressure: Before removing the fuel pump, relieve the fuel system pressure. You can do this by removing the fuel pump fuse or relay, then cranking the engine a few times until it stalls. This will depressurize the lines.
  • Use a New Strainer: When replacing the fuel pump, always replace the fuel strainer (sock) that sits on the bottom of the pump. A clogged strainer can kill a new pump quickly.
  • Check the Fuel Tank: While the tank is removed, take the opportunity to inspect it for rust, debris, or sediment. Clean it out if necessary.
  • Tighten Connections: Ensure all electrical connections are tight and corrosion-free. Use dielectric grease on the connectors to prevent future corrosion.

Final Thoughts

The fuel pump fuse on a 2001 Chevy Silverado is a simple, easy-to-check component that can save you hours of frustration. It is located in the underhood fuse block on the driver’s side, and it is a 20-amp fuse. If the fuse is good, move on to the relay, the reset switch, and finally the pump itself.
