Fuel Pressure Test (With ETCS)

Fuel Pressure Test

Special Tools Required
Fuel pressure gauge (  07406-0040002)
 

Fuel pressure gauge set (  07ZAJ-S5A0100)
 

1.	Relieve the fuel pressure.

2.	Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and fuel pressure gauge.   07406-004000207ZAJ-S5A0100

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. If the pump runs, 5. If the pump does not run, do the fuel pump circuit troubleshooting.

5.	Read the pressure gauge. The pressure should be 320-370 kPa (3.3-3.8 kgf/cm2, 47-54 psi) If the pressure is OK, the test is complete. If the pressure is out of specification, replace the fuel pressure regulator, and the fuel filter, then recheck the fuel pressure.
