Fuel Pump Fuse Location

The fuel pump fuse for a 2000 Chevrolet S10 is located in two potential areas:

1. Under the hood: In the engine compartment fuse box

2. Inside the vehicle: In the instrument panel fuse block

Engine Compartment Fuse Box

To access the engine compartment fuse box:

1. Open the hood

2. Locate the fuse box on the driver's side

3. Remove the cover by turning the fastener

In this fuse box, look for the following:

  • A 20 amp fuse labeled "ECM B"
  • This fuse controls both the Engine Control Module and the fuel pump

Instrument Panel Fuse Block

To access the instrument panel fuse block:

1. Open the driver's side door

2. Locate the fuse panel on the left side of the dashboard

3. Remove the cover to access the fuses

In this fuse block, check for:

  • A 20 amp fuse labeled "ECM BATT"
  • This fuse also provides power to the fuel pump and ECM

Fuel Pump Relay

The fuel pump relay is another crucial component to check. It's located in the engine compartment fuse box. Look for a relay labeled "Fuel Pump" or "ECM".

To test the relay:

1. Remove the relay

2. Swap it with a similar relay (e.g., the horn relay)

3. If the fuel pump works with the swapped relay, the original relay is faulty

Troubleshooting Tips

If you're experiencing fuel pump issues:

1. Check both fuses mentioned above

2. Inspect the fuel pump relay

3. Listen for the fuel pump priming when you turn the key to "ON"

4. If no priming sound, use a multimeter to check for voltage at the fuel pump connector

5. Consider checking the ECM-B fuse as it also affects the fuel pump

Remember, if you're uncomfortable performing these checks, it's best to consult a professional mechanic.
