Core Functions & Engine Protection

1. Receive signal instructions from engine ECU to dynamically control fuel pump operation and adjust fuel supply pressure
2. Maintain stable fuel pressure under idle, acceleration and high-speed driving conditions to guarantee sufficient fuel supply
3. Optimize fuel pump working mode, reduce unnecessary power consumption and lower pump wear
4. Avoid power attenuation, jitter and flameout risks caused by insufficient fuel supply

Common Fault Phenomena That Can Be Solved

• Engine cranks normally but fails to start; no humming sound from fuel pump
• Intermittent difficult startup, especially after hot parking
• Obvious lack of power and hesitation when stepping on the accelerator
• Engine stalls unexpectedly during driving and may restart after cooling down
• Diagnostic scanner detects fault codes P0087, U0109 related to fuel supply system
