How to Change the Fuel Pump in a 1996 Geo Metro

The 1996 Geo Metro has a four-cylinder 1.3 liter engine that uses fuel injection to deliver fuel to the engine at high pressure. The fuel pump is in the fuel tank, which means you must disconnect the fuel tank before you can replace the fuel pump. Experienced home mechanics should be able to do the job in several steps.

Instructions

1

Loosen the fuel tank cap to relieve the pressure in the fuel tank. Disconnect the fuse for the fuel pump relay in the engine compartment. Run the engine until it stalls, then engage the engine to ensure you have completely relieved the pressure in the fuel system.

2

Disconnect the negative battery cable with a socket wrench to prevent accidental sparking from the battery.

3

Siphon the fuel through the filler tube of the fuel tank into a container approved for gasoline. Detach the electrical connector for the fuel pump and fuel sending unit.

4

Raise the vehicle with a floor jack and support it on jack stands. Release the clamps on the filler neck and disconnect the filler neck from the fuel tank. Disconnect the clamp from the inlet hose on the fuel filter and detach the inlet hose from the fuel filter.

5

Disconnect the clamps for the fuel lines to the fuel tank and detach the fuel lines from the fuel tank. Support the fuel tank with a transaxle jack, and remove the mounting bolts for the fuel tank with a socket wrench. Disconnect the fuel tank and lower it from the vehicle with the transaxle jack.

6

Release the clamps for the fuel lines on the fuel pump assembly and detach the fuel lines from the fuel pump assembly. Disconnect the attaching screws for the fuel pump assembly with a socket wrench and remove the fuel pump assembly from the fuel tank.

7

Remove the mounting screws for the fuel pump. then detach the electrical connector for the fuel pump. Disconnect the fuel pump from the rest of the fuel pump assembly.

8

Perform steps 2 through 4 in reverse to complete the fuel pump installation. Fill the fuel tank and connect the negative battery terminal with a socket wrench. Turn the ignition switch to the ON position. Start the engine and check for fuel leaks.
