OPERATIONAL CHECKNOTE: Before disconnecting the vacuum hose, mark it to ensure reconnection at the correct position.
Fuel Pressure Control Solenoid Valve Location:
1. Remove the vacuum hose (blue stripe on black) from the solenoid valve.
2. Disconnect the harness connector.
Fuel Pressure Control Solenoid Operational Test Hook-up:
3. Apply a negative pressure to the nipple to which the black vacuum hose has been connected and check air-tightness with and without the battery voltage applied to the solenoid valve terminal.
