Fuel Pressure Release: Service and Repair

To reduce the risk of fire and personal injury, It is necessary to relieve the fuel system pressure before servicing the fuel system. Unless this procedure is
followed before servicing fuel lines and connections, fuel spray could occur.

When repair to the fuel system has been completed, Start engine and check all connections that were loosened for possible leaks.

1.  Remove fuel cap
2.  Remove fuel pump relay from underhood relay center.
3.  Start engine and allow to stall.
4.  Crank engine for additional 30 seconds.
5.  Remove negative battery cable.
