Fuel Pressure Regulator: Testing and Inspection
The technician should be aware that diagnosis and testing of the fuel pressure regulator should begin at the Powertrain Management level, where testing
begins with "general" symptom diagnosis, and is narrowed to testing of a "specific" subsystem and it's related wiring and components. Following the
appropriate diagnostic routines may prevent misdiagnosis and unnecessary component replacement. Refer to Powertrain Management/Testing and
Inspection/Procedures.
