  1. Turn ignition off. Slowly open fuel tank cap to release pressure in tank. Disconnect 7-pin injector connector. Connect a jumper wire between injector connector (injector side) Dark Green/Orange wire and battery positive terminal.
  2. Connect another jumper wire to injector connector (injector side) White/Dark Blue wire. Momentarily ground jumper wire connected to White/Dark Blue wire no more than 5 seconds. Injector No. 1 will energize open, relieving some fuel pressure. Remove jumper wire from White/Dark Blue wire.
  3. Connect a jumper wire to injector connector (injector side) Brown wire. Momentarily ground jumper wire connected to Brown wire no more than 5 seconds. Injector No. 2 will energize open, relieving some fuel pressure. Remove jumper wire from Brown wire.
  4. Connect another jumper wire to injector connector (injector side) Yellow/White wire. Momentarily ground jumper wire connected to Yellow/White wire no more than 5 seconds. Injector No. 3 will energize open, relieving some fuel pressure. Remove jumper wire from Yellow/White wire.
  5. Remove jumper wire from Dark Green/Orange wire. Energizing 3 different fuel injectors should have relieved enough fuel pressure to safely open fuel system. Use caution when opening fuel system, some residual fuel pressure may be present.
