The FAULT light in a fuel pump switch indicates ___________.

The FAULT light in a fuel pump switch indicates ___________.

• A. The pump is selected ON but output pressure is low
• B. The pump has failed
• C. The pump is overheating
• D. The pump is OFF

Answer: (A)

The FAULT light on the fuel pump switch is an abnormal pressure warning. It lights when you have the pump selected ON but the output fuel pressure is below the required level, signaling that the pump isn’t delivering normal flow. This means the pump is operating but not providing enough pressure, which could be due to a fault in the pump, a blockage, or another issue in the fuel path. It’s not simply a confirmation of a failed pump, and it isn’t indicating overheating or that the pump is OFF. So the best interpretation is that the pump is ON but its output pressure is too low.
