Step-by-step Fuel Pump Wiring Diagram
Step 1: Disconnect the Battery
Before beginning any work on the fuel pump or fuel system, it is essential to disconnect the battery to prevent injury or damage to the vehicle’s electrical system.
Step 2: Locate the Fuel Pump Relay
The fuel pump relay in a 2000 Honda Civic is located under the dashboard on the driver’s side. Remove the plastic cover panel to access the relay.
Step 3: Identify the Color Codes
Identify the different wire colors on the fuel pump relay, fuel pump, and ground connections using the table above.
Step 4: Test the Relay
With the ignition turned on, use a voltmeter to test the fuel pump relay for voltage. If there is no voltage, check the fuse and wiring to the relay.
Step 5: Test the Fuel Pump
If the fuel pump relay is working correctly, use a voltmeter to test the fuel pump for voltage. If there is no voltage, check the wiring between the relay and the fuel pump.
