Spill (figure 5-18) signals the end of injection:
• the fuel solenoid, as commanded by the PCM, de-energizes. This opens the control valve. Fuel spills out the control valve opening and returns to the fill/spill chamber.
• fuel from the injection lines spills back into the rotor through the discharge ports. Near the end of the spill cycle, the rotor spins to close the discharge ports.
• the shoe/roller assemblies are at the top of the cam lobe, putting the plungers in the maximum inward position
