Where is the fuel pump relay located on 2000 Chevrolet truck?

The fuel pump relay location on a 2000 Chevrolet truck depends on the specific model (e.g., Silverado, Tahoe, Suburban, etc.) and whether it's a 2WD or 4WD. There isn't one single location for all.

To find it, you'll need to do one of the following:

1. Consult your owner's manual: This is the best resource. The manual will have a diagram showing the location of all relays and fuses.

2. Check the underhood fuse box: Many Chevrolet trucks have a large fuse and relay box under the hood, often near the battery. Look for a diagram on the inside cover of the box. The relay may be labeled "Fuel Pump" or have a related designation.

3. Check the interior fuse box: Some models may have a smaller fuse and relay box inside the vehicle, usually under the dashboard. Again, check for a diagram.

4. Use a wiring diagram: A wiring diagram specific to your truck's year, make, and model will show the location and circuit path of the fuel pump relay. You can find these online from repair manuals (like Haynes or Chilton) or some automotive parts websites.

Without knowing the exact model of your 2000 Chevrolet truck, I cannot provide a more precise location. Always consult your owner's manual first.
