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 Cut System
The fuel cut solenoid valve receives a signal from the ECM if the ignition is turned off. During deceleration, a signal is also received when the temperature is normal, the clutch is not depressed, primary throttle valve is closed and engine speed exceeds 2500 RPM. If all of these conditions exist during deceleration, the fuel cut system stops fuel flow to the carburetor slow system.
