WARNING: This page is about a different car, the 2003 Pontiac Bonneville, 2003 Buick Park Avenue, and 2003 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
- Turn OFF the ignition. Disconnect the negative battery cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine. Remove fuel injector sight shield (upper engine cover) from engine. Remove the fuel pressure connection cap from the fuel rail.
- Connect Fuel Pressure Gauge (J-34730-1A) to the fuel pressure connection. Wrap a shop towel around the fuel pressure connection while connecting the fuel pressure gauge in order to avoid spillage. Install the bleed hose into an approved container and open the valve to bleed the system pressure.
- The fuel connections are now safe for servicing. Drain any fuel remaining in the fuel pressure gauge into an approved container. Remove the fuel pressure gauge.
