Toyota Land Cruiser 100 Series & Lexus LX470 Fuel System, Problems & Maintenance Guide

The Toyota Land Cruiser 100 Series and Lexus LX470 are known for long service life, strong 4.7L 2UZ-FE V8 engines, and excellent durability. However, as these vehicles age, fuel system components can begin to wear and cause drivability problems.

Common Fuel System Problems

Typical fuel system issues may include:

• Hard starting

• Long cranking time

• Engine hesitation

• Loss of power

• Intermittent stalling

• Low fuel pressure

• No-start condition

• Incorrect fuel level readings

These problems may be related to the fuel pump, fuel pump assembly, fuel strainer, fuel filter, wiring, relay, or fuel level sending unit.

Fuel Pump Maintenance

For older Toyota Land Cruiser 100 Series and Lexus LX470 models, fuel pump performance should be checked when starting or fuel pressure problems appear.

Before replacing the pump, inspect:

• Fuel pressure

• Electrical connector

• Fuel pump wiring

• Strainer condition

• Fuel level sensor

• Fuel pump relay

• Fuel tank contamination

A complete Land Cruiser fuel pump assembly or Lexus LX470 fuel pump assembly may be a good option when several original components are already worn.

Compatible Applications

This guide mainly applies to:

• Toyota Land Cruiser 1998–2001
