Repressurizing Fuel System
- Using scan tool, perform ASD fuel system test in order to pressurize fuel system. When using ASD fuel system test, auto shutdown relay remains energized (battery voltage is supplied to fuel injectors, ignition coils and heating element in oxygen sensor) for 7 minutes, until test is stopped, or ignition is turned off.
- Check for and clear any Diagnostic Trouble Codes (DTCs) that may have been set due to fuel pump relay removal. See procedures in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
