Checking the power cable








- Ignition off
- Disconnect the injector connector
- Ignition on.
Connect a voltmeter between injector connector terminal 1 (control module side) and ground.









The voltmeter should read battery voltage for 2 seconds immediately the ignition is switched on.

OK - Checking injectors

Not OK - Checking wiring and terminals

-------------------------------------------------

Checking injectors
Connect an ohmmeter between injector connector terminals 1 and 2 (injector side).









The ohmmeter should read approximately 14-15 ohms at +20°C.
