So Fix it

Warm up the engine for one to two minutes before shutting it off. This will cause any problems with the Mazda to show up during the diagnostic reading.

Pop open the hood and locate the "Tester" box, which is a 2-by-2-inch box on the driver side of the engine.

Find the connections labeled "STI and "SIG RTN." Securely connect a 3-inch metal wire, with a plastic protective covering, from the SIG RTN to the STI slot. Wiggle the wire to ensure the wire will not become loose during the test.

Turn the ignition on, but do not start the engine. Watch for the blinking "Check Engine" light. With a paper and writing utensil, write down the pattern of short and long intervals between flashes of light. The intervals corresponds with codes in a repair manual. Check your local library, repair shop or online database for a list of engine codes.

Start the engine, and disconnect the electrical connect for the fuel pump. Wait for the engine to stall, and turn the ignition switch off.

Disconnect the cable on the batterys negative terminal with a socket wrench to prevent sparking. Loosen the filler cap for the fuel tank. Raise the vehicle with jack, and it on jack stands. Place a gasoline container under the drain plug with a socket wrench, and remove the drain plug. Drain the fuel tank into the gasoline container.

Disconnect all hoses from the fuel tank, and support the fuel tank with a jack. Remove the mounting nuts for the fuel tank with a socket wrench. Lower the fuel tank from the vehicle.

Clean the area around the fuel pump to prevent debris from entering the fuel tank while you replace the fuel pump. Remove the mounting screws for the fuel pump with a socket wrench, and detach the fuel pump from the fuel tank. Discard the old gasket on the fuel tank.

Place a new gasket into position on the fuel tank. Install the new fuel pump by performing steps 2 through 4 in reverse order. Fill the fuel tank with fuel, start the engine and check for leaks in the fuel system.
