Where is the fuel relay switch located on a 1992 Chevy Astro van?

The fuel pump relay location in a 1992 Chevy Astro van isn't standardized across all trims and options. It's *usually* found in one of these places, but you'll need to check your vehicle's specific fuse box diagrams:

* Under the hood in the main fuse/relay box: This is the most common location. The box is often located near the battery. The relay itself might be labeled, or you might need to consult your owner's manual or a wiring diagram to identify it.

* Inside the passenger compartment fuse box: Some models might have it inside the dashboard, usually under the steering wheel or on the side panel.

To find it definitively:

1. Consult your owner's manual: This is your best bet. It should have a diagram of the fuse and relay boxes, showing the location of the fuel pump relay.

2. Look for a wiring diagram: A wiring diagram specific to your 1992 Chevy Astro van will clearly show the location and the relay's circuit. You can find these online through various auto parts websites (like AutoZone or Advance Auto Parts) by entering your year, make, and model.

3. Check online forums: Searching online forums dedicated to Chevy Astro vans (like on forums.chevyhvac.com) may yield results from other owners who've located the relay on their similarly equipped vans.

Remember: Always disconnect the negative battery terminal before working with electrical components in your vehicle. If you're unsure about any part of this process, it's best to seek help from a qualified mechanic.
