how to fix my Genesis G70 fuel gauge that shows empty all the time

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shock.
• Allow the vehicle to cool down if it was recently running.

2. Access Fuel Sender Unit

• Tools Required: Socket set, screwdrivers, safety glasses, and gloves.
• Remove the rear seat bottom cushion to access the fuel pump access panel.
• Unscrew the access panel and lift it to expose the fuel sender unit.

3. Inspect and Test Fuel Sender

• Disconnect the wiring harness from the fuel sender unit.
• Use a multimeter to measure the resistance of the fuel sender (should vary based on the float position; typically between 0-90 ohms).
• If the readings are out of specification, replace the fuel sender unit.

4. Reassemble Components

• Reconnect the wiring harness to the new or tested fuel sender unit.
• Replace the access panel and secure it with screws.
• Reinstall the rear seat bottom cushion.

5. Reconnect Battery and Test

• Reconnect the battery terminals.
• Start the vehicle and observe the fuel gauge operation; it should now reflect the correct fuel level.
