Fuel Pressure Test

1.Relieve the fuel pressure.

2.Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and fuel pressure gauge (A).

 

3.Start the engine and let it idle.

  • If the engine starts, go to 5.
  • If the engine does not start, go to 4.

4.Check to see if the fuel pump is running: listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on.


5.Read the pressure gauge. The pressure should be 320-370 kpa (3.3-3.8 kgf/cm2, 47-54 psi)
