Here's how it works:
* Ignition Switch: When you turn the key to the "ON" position, power is supplied to the fuel pump.
* Fuel Pump Relay: The fuel pump is controlled by a fuel pump relay, which is activated by the ignition switch. The relay acts as a switch to control the flow of power to the fuel pump.
* Fuel Pump Motor: The fuel pump motor is directly wired to the relay, and it runs only when the ignition switch is in the "ON" position.
Important Considerations:
* Checking the Fuel Pump: If you suspect a fuel pump issue, you'll need to test the pump directly, bypassing the relay and ignition switch.
* Fuel Pump Relay: The fuel pump relay can fail, preventing the pump from operating.
* Wiring Issues: Check for any loose connections or damaged wiring between the ignition switch, relay, and fuel pump.
* Fuel Pump Motor: A faulty fuel pump motor can also be the source of the problem.
If you are experiencing fuel pump issues, it's recommended to have a qualified mechanic diagnose the problem.
