2000 Silverado Fuel Pump Fuse: Location, Replacement, and Troubleshooting Guide

The bottom line: On a 2000 Chevy Silverado, the fuel pump fuse is located in the under-hood fuse box on the driver's side of the engine compartment. It is typically a 20-amp fuse, and if your truck cranks but won't start, a blown fuse is often the first thing to check. Most Silverado models from this year do not have a separate fuel pump reset switch, so the fuse and relay are your primary diagnostic points.

If you own a 2000 Chevrolet Silverado 1500 or 2500, and you're dealing with starting problems, stalling, or a no-start condition, the fuel pump fuse is one of the most common and easiest things to check. This guide will walk you through everything you need to know: where to find the fuse, how to test it, what to do if it's blown, and when to replace the actual fuel pump. We'll also cover how to safely replace the pump yourself and recommend a reliable aftermarket option.

Where Is the Fuel Pump Fuse on a 2000 Chevy Silverado?

The fuel pump fuse on a 2000 Chevy Silverado is located in the under-hood fuse box (also called the Underhood Electrical Center). This box is situated near the driver's side of the engine compartment, typically on the driver's side fender well or near the battery.

To access the fuse box:

  • Open the hood and locate the black plastic fuse box on the driver's side.
  • Remove the cover by pressing the tabs on the sides.
  • Look for the diagram on the underside of the fuse box cover, or refer to the owner's manual.

Fuse location specifics:

  • 2000 Silverado 1500 (C/K GMT400 generation): The fuel pump is controlled by fuse #15 in the Underhood Fuse/Relay Center, which is a 20-amp MINI fuse labeled "ECM B" or "Fuel Pump."
  • 2000 Silverado 2500 (GMT800 generation): The fuel pump fuse is typically in slot F58, a 20-amp MINI fuse labeled "Ignition Switch, Fuel Pump, PRND321 Display, Crank."

Common fuse specs:

  • Fuse type: 20-amp MINI fuse
  • Location: Under-hood fuse box, driver's side
  • Label: "Fuel Pump," "ECM B," or "IGN SW" depending on the exact model

Does a 2000 Silverado Have a Fuel Pump Reset Switch?

No, the 2000 Chevy Silverado does not have a separate fuel pump reset switch or inertia switch.

This is a common point of confusion. Many DIY guides and videos online show a red reset button for Ford F-150s, but Chevrolet Silverados from this era never had this feature. The fuel pump system is protected solely by the fuse and relay.

If you see a video or guide claiming there's a reset button in the trunk, kick panel, or under the dash, it's likely written for a Ford vehicle. The 2000 Silverado relies on the fuse and relay for electrical protection, and the PCM (Powertrain Control Module) controls the fuel pump operation based on the ignition signal.

Symptoms of a Bad Fuel Pump Fuse on a 2000 Silverado

A blown fuel pump fuse can cause several symptoms that mimic a failing fuel pump or other electrical issues:

  • Engine cranks but won't start: This is the most common symptom. If the fuel pump fuse is blown, the pump won't receive power, and no fuel will reach the engine.
  • No fuel pump prime sound: When you turn the key to the "on" position (before starting), you should hear a 2-3 second whirring sound from the fuel pump in the tank. If you don't hear this, the fuse or pump may be faulty.
  • Engine stalls while driving: A partially blown fuse or intermittent connection can cause the fuel pump to lose power, causing the engine to die suddenly.
  • Loss of power under load: If the fuse is damaged but not fully blown, the pump may not deliver enough fuel pressure, causing hesitation or surging.

How to Test the Fuel Pump Fuse on a 2000 Silverado

Testing the fuel pump fuse is simple and requires only a few tools:

  1. Locate the fuse box under the hood on the driver's side.
  2. Identify the fuel pump fuse using the diagram on the cover or the owner's manual.
  3. Remove the fuse using a fuse puller or needle-nose pliers.
  4. Inspect the fuse visually: Look for a broken metal strip inside the fuse. If it's visibly broken, the fuse is blown.
  5. Test with a multimeter: Set the multimeter to continuity mode (ohm setting). Place one probe on each of the two metal prongs on the top of the fuse. If you hear a beep or see a low resistance reading (near 0 ohms), the fuse is good. If you get no reading, the fuse is blown.
  6. Test with a test light: Clip the test light to a ground (like a metal bolt on the engine block). Touch the probe to each of the two metal prongs on the top of the fuse. If the light illuminates on both prongs, power is reaching the fuse. If it only lights on one side, the fuse is blown.

Important safety note: Always work with the ignition off when removing or replacing fuses.

What to Do If the Fuel Pump Fuse Keeps Blowing

If you replace the fuel pump fuse and it blows again immediately or after a short time, you have a deeper electrical issue. Common causes include:

  • Short circuit in the fuel pump wiring: The wires running from the fuse box to the fuel pump may be chafed or damaged, especially where they pass through the frame or near the fuel tank.
  • Failing fuel pump motor: A fuel pump that is drawing excessive current (due to wear, contamination, or a seized motor) can cause the fuse to blow. This is a common sign that the pump itself needs replacement.
  • Faulty fuel pump relay: The relay can fail in a way that causes the pump to run continuously or draw too much current, leading to a blown fuse.
  • Corrosion or loose connections: Corroded fuse terminals or loose wiring connections can cause resistance and heat buildup, which can blow the fuse.

Troubleshooting steps:

  1. Check the fuel pump relay (located in the under-hood fuse box). Swap it with a relay of the same rating (like the horn relay or A/C relay) to see if the problem moves.
  2. Inspect the wiring harness from the fuse box to the fuel tank for damage, especially near the frame rails and the rear axle.
  3. If the wiring looks good, the fuel pump itself is likely the culprit and needs to be replaced.

How to Replace the Fuel Pump on a 2000 Chevy Silverado

If you've ruled out the fuse and relay, and the pump is not working, it's time to replace the fuel pump assembly. Here's a step-by-step guide for the 2000 Silverado:

Safety first: Work in a well-ventilated area. Keep a fire extinguisher nearby. Avoid smoking or using open flames.

Tools needed:

  • Socket set and wrenches
  • Fuel line disconnect tool
  • Jack and jack stands
  • Drain pan
  • Safety goggles and gloves

Step 1: Relieve fuel system pressure

  • Locate the Schrader valve on the fuel rail (near the engine).
  • Remove the fuel pump fuse or relay from the under-hood fuse box.
  • Start the engine and let it run until it stalls. This depressurizes the system.
  • Crank the engine for a few seconds after it stalls to ensure all pressure is released.

Step 2: Disconnect the battery

  • Disconnect the negative battery terminal to prevent any electrical sparks or accidental fuel pump activation.

Step 3: Access the fuel pump

  • On a 2000 Silverado, the fuel pump is located inside the fuel tank. The easiest way to access it is to remove the bed of the truck.
  • If you don't want to remove the bed, you can drop the fuel tank. This requires supporting the tank with a jack, disconnecting the filler neck, and lowering it carefully.
  • Removing the bed: Disconnect the taillight wiring, remove the bed bolts (typically 6-8 bolts), and lift the bed off with a helper or an engine hoist. This is generally faster than dropping the tank.

Step 4: Remove the old fuel pump

  • Once the tank is accessible, disconnect the electrical connector and fuel lines from the top of the pump assembly.
  • Use a fuel line disconnect tool to release the quick-connect fittings.
  • Remove the retaining ring (lock ring) using a hammer and a punch or a special tool.
  • Lift the pump assembly out of the tank. Note the orientation of the float arm and the pickup sock.

Step 5: Install the new fuel pump

  • Transfer any necessary components from the old assembly to the new pump (if you're replacing only the pump, not the entire module).
  • Make sure the new fuel strainer (sock) is properly installed.
  • Lower the new pump assembly into the tank, ensuring the float arm is free and the pickup is at the bottom of the tank.
  • Install the retaining ring and tighten it securely.
  • Reconnect the fuel lines and electrical connector.

Step 6: Reassemble and test

  • Reinstall the bed or raise the fuel tank back into place.
  • Reconnect the battery and install the fuel pump fuse.
  • Turn the key to the "on" position (without starting) and listen for the fuel pump prime cycle. You should hear a 2-3 second hum.
  • Start the engine and check for leaks at the fuel pump connections and fuel lines.
