Is ther a relay that controls fuel pump for 2003 kia optima need location is no to under the hood fuse yes did see some relays on top of box in dash?

The fuel pump relay for a 2003 Kia Optima is not typically located in the fuse box under the hood, nor is it usually found in a relay box on top of the dashboard. While some vehicles might have it in one of those locations, it's less common for the Optima.

The fuel pump relay in a 2003 Kia Optima is more often found within the under-dash fuse box, often tucked away and difficult to see. The fuse box itself is usually located on the driver's side, below the steering wheel or dashboard.

To find it:

1. Consult your owner's manual: This is the best resource. It should have a diagram showing the fuse and relay box layouts.

2. Look carefully inside the under-dash fuse box: Many relays are similar in appearance, so you'll need to visually inspect the relays and possibly use a multimeter to identify the correct one. It's a good idea to take photos before disconnecting anything to ensure you can put it back.

3. Use a wiring diagram: A wiring diagram for your specific year and model Optima will show the circuit for the fuel pump and help you trace the wire to locate the correct relay. You may find free diagrams online through forums dedicated to Kia Optima or automotive repair resources.

Caution: Working with car electrical systems can be dangerous. If you are not comfortable doing this yourself, take your vehicle to a qualified mechanic. Improperly handling relays or fuses can cause damage to your vehicle or create a fire hazard.
