Recommended checks
Read specified vs actual rail pressure at cranking, idle and load
Check low-pressure supply (pressure/volume) first
Check control valve/regulator operation
Measure injector return flow where applicable
Inspect wiring and connectors of pressure components
Powertrain: engine, transmission and driveline systems.
