RELIEVING FUEL PRESSURE
In the event that servicing the EFI fuel system necessitates removal of the fuel delivery hose, extreme caution must be
exercised. The fuel system is under high pressure even with the engine not running. Disconnecting any part of the
fuel delivery system, without first depressurizing the system, will result in a sudden release of pressurized gasoline at
the connection. To prevent possible serious injury or death, fuel pressure must be relieved before disconnecting or
removing the pump, hose and throttle body.
Either of these suggested procedures MUST be followed before attempting ANY service work on the EFI fuel system.
Following these will relieve any pressure in the fuel hose prior to opening the fuel system.

TO RELIEVE FUEL PRESSURE

• Shut off engine, disconnect battery, See Disconnecting the Battery- Gasoline Vehicles on page 1-3.
and wait 15 minutes or more to allow pressure to dissipate.
– or –
• Unplug fuel pump module at fuel tank and crank engine for 5 seconds to start reducing fuel pressure. Pause and
repeat an additional 5 seconds to allow pressure to dissipate.
