Fuel Pressure: Testing and Inspection

Fuel System Diagram:

FUEL PRESSURE
With the ignition "ON" and engine "OFF" (zero vacuum), system fuel pressure should be 284 - 325 kPa (41 - 47 psi). The ignition may have to be cycled "ON" more than once to obtain maximum pressure. When pump stops, pressure may vary slightly then should hold steady.

For additional information, warnings and cautions, refer to Computers and Control Systems / System Diagnosis / Diagnostic Chart A-7.
