Where is the fuel pump relay switch on a 2000 chevy s10?

The fuel pump relay location on a 2000 Chevy S10 is under the hood, in the underhood fuse block/relay center. However, the *exact* location within that fuse block varies slightly depending on engine and options. It's often near other relays associated with ignition or engine functions.

To find it:

1. Locate the underhood fuse block: This is usually a black plastic box near the battery, often mounted to the inner fender.

2. Open the fuse block cover: This will expose the relays and fuses. There's usually a diagram on the inside of the cover showing what each relay and fuse controls. Check this diagram first!

3. Look for the fuel pump relay: The diagram will usually indicate it as "Fuel Pump" or something similar. If not explicitly labeled, you'll have to consult a repair manual (online or printed) with a diagram specific to your engine size (2.2L, 4.3L etc.).

4. If the diagram is missing or unclear: Many online resources provide diagrams specific to 2000 Chevy S10's. Search for "2000 Chevy S10 underhood fuse box diagram" and choose a website showing your engine.

Important Note: Before working on electrical components, always disconnect the negative terminal of your battery to prevent accidental short circuits.
