| 1 - FUEL SUPPLY TO FUEL RAIL |
| 2 - HIGH PRESSURE FUEL PUMP |
| 3 - FUEL QUANTITY SOLENOID |
The fuel quantity solenoid is located in the back of the high pressure pump. The solenoid is pulse width modulated by the ECM and meters the amount of fuel that flows into the high pressure elements inside of the high pressure pump. The solenoid is also inactive during the first 30 seconds to allow maximum fuel pressure to the fuel rail during start up. See Fig 1.
