Description

Function of the Fuel Pump Solenoid

The fuel pump solenoid controls fuel flow to or within the high-pressure fuel pump. It acts as an electronically controlled valve that the ECU uses to regulate fuel delivery based on engine demand. A faulty solenoid causes erratic fuel pressure, hard starting, stalling, poor performance, and can prevent the engine from running.

Common Diagnostic Trouble Codes (DTCs)
