Fuel Pressure: Specifications

Fuel Pressure 345-414 kPa (50-60 psi).

Volume
Monitor the fuel pressure for 1 minute.
^ If the fuel pressure decreases more than 34 kPa (5 psi) within the specified time, locate and replace the leaking fuel injector(s).

If the fuel pressure does not decrease more 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 more than 14 kPa (2 psi) in 5 minutes.

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