Fuel System Pressure Relief (SATURN)
Fuel pressure may be relieved by using one of following methods:
- Connect scan tool. Start engine. Select SPECIAL TESTS, and then PCM/EC. Select FUEL PUMP under fuel delivery and command fuel pump off. Engine will stall in 3-5 seconds. Turn ignition off.
- Install Fuel Pressure Gauge (SA9127E) and 90-Degree Adapter (SA9403E) to fuel pressure test port. When installing fuel pressure gauge, wrap shop towel around pressure connection to absorb fuel leakage. Install gauge bleed hose in container. Open bleed valve to bleed fuel pressure.
