For 1990-2009 cars

Caution: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.

Notice: Do not perform this procedure if the engine is hot. Unburned fuel entering the catalytic converter could damage the converter catalyst.

1. Loosen the fuel filler cap in order to relieve the fuel tank pressure.
2. Remove the relay box cover from the relay box.
3. Remove the fuel pump relay (1) from the relay box (2).
4. Crank the engine, and allow the engine to start and to stall.
5. Crank the engine for an additional 3 seconds in order to relieve any remaining fuel pressure.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

6. Disconnect the negative battery cable in order to avoid any additional fuel discharge.
7. Install the fuel pump relay (1) to the relay box (2).
8. Install the relay box cover onto the relay box.
