Fuel Pressure Relief (PFI)
WARNING:
ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT
allow fuel to contact engine or electrical components.
- Fuel system is under pressure. Relieve pressure before servicing fuel system. Fuel pressure may be relieved using one of 2 different methods.
- One method is to disconnect fuel pump at rear body connector. Start engine and allow to run until it stops. Operate starter for 3 seconds to remove remaining fuel from fuel lines. Reconnect fuel pump once repair is complete.
- The other method is to install Fuel Pressure Gauge (J-34730-1) on fuel pressure connection. When installing fuel pressure gauge, wrap shop towel around pressure connection to absorb fuel leakage.
- Place gauge bleed hose in container. Open bleed valve to bleed fuel pressure.
