Fuel Pressure

Fuel pressure 395-464 kPa (57-67 psi).

^ If the fuel pressure is greater than the specified range, replace the fuel pump module.
^ If the fuel pressure is less than the specified range, test, inspect, and repair the items listed below. If all items test normal, replace the fuel pump module.

Volume
Monitor the fuel pressure for 1 minute.
^ If the fuel pressure does not decrease greater than 34 kPa (5 psi) within the specified time, replace the fuel pump module.

Relieve the fuel pressure to 69 kPa (10 psi). Verify that the fuel pressure does not decrease greater than 14 kPa (2 psi) in 5 minutes.

If the fuel pressure decreases greater than the specified value, replace the fuel pump module.
