Fuel Pressure

2003 Volkswagen Jetta Sedan (9M2) L4-2.0L (AZG)SECTION Fuel Pressure



Fuel Delivery Rate, Checking







- Compare quantity of fuel delivered with chart.
- Minimum delivery cubic cm/30 seconds
- Voltage at fuel pump with engine not running and pump activated (approx. 2 Volts less than battery voltage).

Example:
During test, 12.2 Volts is measured at battery. The fuel pump voltage is approx. 2 Volts less than battery voltage equating to a minimum delivery of 200 cubic cm/30 s.

Fuel Pump, Checking







- Compare the quantity of fuel delivered with specification.
*) Minimum delivery cubic cm/30 seconds
**) Voltage at fuel pump with engine stationary and pump running (approx. 2 volts less than battery voltage).

Example:
During the test a voltage of 12.5 volts is measured at the battery. As the voltage at the pump is approx. 2 volts less than the battery voltage then this will equate to a minimum delivery of 200 cubic cm/30 s.
