Where is fuel pump relay on 2007 Chevy Colorado?

The fuel pump relay location on a 2007 Chevy Colorado is in the underhood fuse block. However, there isn't a single, universally labeled "Fuel Pump Relay". It's often integrated into the underhood fuse block and may be labeled differently or only identified by its function within a wiring diagram.

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The manual should have a diagram of the fuse and relay box showing the location and function of each relay.

2. Look for a diagram on the fuse box cover: Many fuse boxes have a diagram printed on the inside of the cover, though this diagram might not be perfectly clear or complete.

3. Use an online resource: Search online for a "2007 Chevy Colorado fuse box diagram". Many websites and forums dedicated to car repair offer these diagrams. Be sure the diagram you find is specifically for a 2007 Colorado, as these can vary slightly by trim level and engine type.

Once you have a diagram: Look for relays associated with the fuel system, fuel pump, or injection. These will often be near other relays related to engine functions.

Remember to disconnect the negative battery terminal before working with the fuse box or any electrical components to prevent accidental short circuits.
