Fuel System Pressure Relief

WARNING: This page is about a different car, the 1998 Pontiac Grand Am and 1998 Oldsmobile Achieva. However, it is still accessible from the selected car via links, so may be relevant.

Fuel system is under pressure. Pressure must be relieved prior to servicing fuel system. Fuel pressure may be relieved by using the following method:

Loosen fuel filler cap to relieve tank pressure (do not tighten at this time). Disconnect fuel pump connector. Start and run engine until it stalls. Crank starter for 3 seconds to remove remaining fuel from fuel lines. Turn ignition off. Reconnect fuel pump connector. Disconnect negative battery cable to avoid possible fuel discharge in accidental attempt to start engine.
