FUEL PRESSURE

Ignition ON Engine OFF 40.5 to 47.0 psi

With the ignition "ON" and engine "OFF" (zero vacuum), fuel pressure at the pressure connection should be 284-325 kPa (41-47 psi). If the pressure is too low, poor performance could result. If the pressure is too high, excessive odor and DTC 45 may result see CHART A-7 Fuel System Diagnosis under Computer and Control Systems/System Diagnosis/Procedures/Diagnostic Charts/A Charts.
