| The fuel volume control valve default is closed without electrical supply. An open circuit connector will prevent the engine from running. |
| The VCV cannot be replaced as a separate component in service. |

| New injectors can be installed in any cylinder and DO NOT have to be configured. |
| Each Injection event is controlled by a charge and discharge cycle allowing energy to dissipate in, and recover from, the injector. Never disconnect the wiring connector when the vehicle is running. The injector may remain open thus causing engine damage. |
| For safety reasons, the engine must be at standstill for 30 seconds before starting work on the HP fuel systems. |
