Fuel Injectors

  1. Listen to injectors during cranking and at idle. They should make ticking sound. Frequency of sound should increase as engine speed increases.
  2. Except where noted, disconnect injector connector at injector. Check resistance between injector terminals. See INJECTOR RESISTANCES  table. For testing rear bank injectors on 3000GT, disconnect rear bank connector. Check resistance between terminals indicated in 3000GT REAR BANK INJECTOR CHECK  table. For testing right bank injectors on Galant 3.0L, disconnect intermediate connector. Check resistance between terminals indicated in GALANT RIGHT BANK INJECTOR CHECK  table. For testing Montero 3.5L or Montero Sport 3.0L & 3.5L injectors, disconnect intermediate connector. Check resistance between intermediate connector terminals indicated in MONTERO SPORT 3.0L & 3.5L INJECTOR CHECK  table.
