Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pump Control
The electrical system has a fuel pump relay, controlled by EEC module, which provides power to fuel pump under various operating conditions. When ignition is in "OFF" position, EEC power and fuel pump relay contacts are open.
After engine starts, and ignition is returned to "ON" position, power to fuel pump is again supplied through fuel pump relay. EEC module senses engine speed and shuts off fuel pump relay when engine stops (or when engine speed falls below 120 RPM).
