Fuel System Pressure Release
WARNING: This page is about a different car, the 1997 Infiniti I30. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
Remove fuel pump fuse from fuse block. Start engine. Let engine run until it stalls. Crank engine 2-3 times after engine has stopped to release all fuel pressure. Turn ignition off, and reinstall fuse.
