Fuel System Pressure Release
CAUTION:
When servicing fuel system related components, high fuel pressure may be present in fuel lines and component parts. Relieve pressure before attempting to open system for component replacement. DO NOT
allow fuel to flow onto engine or electrical parts or allow an open flame in area while testing fuel system components.
- 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.
- Connect one end of a jumper wire to terminal No. 2 of injector harness and tough other end to battery positive for no more than 5 seconds. This releases system pressure. Remove jumper wires. Continue fuel system service.
