Solenoid, Fuel Quantity: Description
The fuel quantity solenoid (2) is located in the back of the high pressure pump. The solenoid is pulse width modulated by the Powertrain Control Module (PCM) 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.
