Where would the fuel pump relay for a 1992 Chevrolet Caprice with 305 engine be located?

The fuel pump relay location on a 1992 Chevrolet Caprice with a 305 engine isn't standardized in a single spot like some cars. It could be in a few places within the underhood fuse/relay center. You'll need to consult your owner's manual (if you have it) or a wiring diagram specific to that year and model.

The most common locations to check are:

* Underhood fuse box: This is the most likely place. The fuse box is usually located near the battery, often under a cover. Look for a diagram on the inside of the fuse box cover itself. It will show you where the relay is located, often labeled as "Fuel Pump" or something similar.

* Passenger compartment fuse box: While less common for the fuel pump relay, some GM vehicles of that era might have it inside the passenger compartment. Again, check the fuse box diagram.

Without the manual or a wiring diagram, you'll have to:

1. Visually inspect the underhood fuse box: Look for a relay that's of a similar size and shape to other relays in the box. Many fuel pump relays are the same size and shape as other relays in the box so you'll need to reference the diagram to identify it.

2. Check for labels: Look for any markings on the relays.

3. Use a multimeter: If you're comfortable using a multimeter, you could test the continuity of each relay to see if it matches the circuit for the fuel pump. (This method requires a wiring diagram to know which wires to test.)

Caution: Working with automotive electrical systems can be dangerous. If you're not comfortable with this, take your Caprice to a qualified mechanic.
