Fuel Pump Relay
Switches the fuel pump's high-current supply on command from the module. Fails both ways: open, giving a no-start; or welded closed, leaving the pump running whenever the battery is connected — which flattens the battery and matters in a collision.
Also known as: pump relay, fuel relay, fp relay

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
