Test Description

2 - Relieve fuel pressure by connecting Fuel Pressure Gauge (J34730-1) or equivalent to fuel pressure connection on fuel rail. Place fuel pressure gauge bleed hose in an approved gasoline container. With ignition off, open valve on fuel pressure gauge.
3 - Record lowest voltage displayed by DVOM after first second of test. (During first second, voltage displayed by DVOM may be inaccurate due to initial current surge).
- Voltage displayed by DVOM should be within specified range.
- Voltage displayed by DVOM may increase throughout test as fuel injector windings warm and resistance of fuel injector windings changes.
- An erratic voltage reading (large fluctuations in voltage that do not stabilize) indicates an intermittent connection within fuel injector.
