EFI-1X5 Injector X

Checking injector








- Ignition off.
- Disconnect injector.
Connect an ohmmeter between injector connector terminals 1 and 2.









The ohmmeter should read approximately 16 ohms at 20°C.

OK - Check cable between injector terminal 2 and engine control module (ECM) #A10 (EFI-115), #A38 (EFI-125), #A24 (EFI-135), #A23 (EFI-145), #A9 (EFI-155) for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Then continue with Verification.
