For Primary Fuel Injectors

• Remove the air cleaner housing (see Air Cleaner Housing Removal).
• Disconnect the primary fuel injector connector [A].

• Connect a digital meter to the terminals in each primary fuel injector [A].
• Measure the primary fuel injector resistance.

Primary Fuel Injector Resistance Standard: About 11.7 12.3 Ω at 20В°C
(68В°F)

• If the reading is out of the standard, replace the primary fuel injector.
• If the reading is within the standard, check the power source voltage (see Fuel Injector Power Source Voltage Inspection).
