Fuel Injector(s)

Disconnect fuel injector harness connector. Measure resistance across injector terminals at each injector. Resistance should be as specified. See INJECTOR RESISTANCE SPECIFICATIONS table.

⁽¹⁾	Injector resistance specification is at 140°F (60°C).

⁽²⁾	Information not available at time of publication. Solenoid should have resistance; however, infinite resistance indicates an open injector wiring.

NOTE: If injectors are dirty, they should be cleaned using approved injector cleaning procedure before performing PFI INJECTOR BALANCE TEST below.
