GASOLINE VEHICLE - FUEL SYSTEM Relieving Fuel Pressure
21
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
Option 1:
1. Turn the key switch to OFF.
2. Disconnect the battery.
3. Wait 15 minutes or more to let the fuel pressure dissipate.
Option 2:
1. Turn the key switch to OFF.
2. Disconnect the fuel pump module at the fuel tank.
3. Crank the engine for 5 seconds to start reducing the fuel pressure.
4. Wait for 2-5 seconds.
5. Crank the engine for 5 seconds to let the fuel pressure dissipate.
NOTE: To absorb any residual fuel the may be present in the fuel hose, place a rag or towel around the hose at
the end being disconnected.
