Fuel System Pressure Release

CAUTION: ALWAYS relieve pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
  1. Loosen fuel filler cap to release tank pressure. Disconnect injector wiring harness from engine harness. Connect a jumper wire between terminal No. 1 of injector harness and engine ground. See Fig 1.
  2. Connect one end of a second jumper wire to terminal No. 2 of injector harness and touch other end to battery positive for no more than 5 seconds. This releases system pressure. Remove jumper wires. Continue fuel system service.
