FUEL INJECTOR BALANCE TEST WITH SPECIAL TOOL

DESCRIPTION

Fuel Injector Balance Test With Special Tool

Fuel Injector Balance Test Example (Typical)

The scan tool is first used to energize the fuel pump. The fuel injector tester is then used to pulse each injector for a precise amount of time, allowing a
measured amount of fuel into the manifold. This causes a drop in system fuel pressure that can be recorded and used to compare each injector.
