How to Replace a Fuel Pump in a Nissan Maxima

by Contributor

The Nissan Maxima fuel pump is electric so you should check its fuses and relays and before inspecting the fuel pump. If your vehicle still has difficulty getting fuel and your tank has fuel, you may need to clean or replace the fuel pump. The Nissan Maxima comes in a variety of styles and trim levels and this can affect your choice of fuel pump.

Step 1

Select the new fuel pump for your Nissan Maxima. You will not only need to know the make and model, but also the engine size. Models made from 1981 to 1984 have a 2.4 L or 2.8 L diesel engine, and 1985 to 1999 models have a 3.0 L engine in several different types and configurations. Models built from 2000 to 2003 have a 3.0 L or 3.5 L engine, and the Nissan Maxima has been equipped with a 3.5 L engine since 2004.

Step 2

Prepare your vehicle for fuel pump servicing. Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Locate the access panel under the rear seat or in the trunk, depending on the specific model.

Step 3

Disconnect the electrical connectors for the fuel gauge and fuel pump, then remove the fuel send and return hoses. Some models require you to unbolt the fuel pump from the fuel tank. Others require you remove a locking ring and lift the fuel pump out of the tank. Discard the O-ring.

Step 4

Install the new fuel pump using the items included in the kit and be sure to replace the O-ring seal and clamps on the fuel line hoses. Use a torque wrench to tighten the attaching bolts for the fuel tank strap to 22 in. lbs. (if present).

Complete the installation by reversing the removal procedure.
