INSPECTION

1. Measure the resistance of the injectors between the terminals using an ohmmeter.

Resistance: 13 - 16 at 20° C (68° F)

2. If the resistance is not within specifications, replace the injector.

INSTALLATION





1. Install a new grommet and 0-ring to the injector.

Injector Installation:

3. While turning the injector to the left and right, install it on to the delivery pipe.
