4. Check that battery voltage is 11 V or more.
5. Measure fuel pressure at each condition.
If measured pressure is out of specification, refer to Fuel Pressure Check and check each possibly defective part. Replace if found defective.
a. Turn ignition switch ON to operate fuel pump and after 2 seconds turn it OFF. Repeat this 3 or 4 times and then check fuel pressure.
Fuel pressure specification
With fuel pump operating and engine stopped: 360 - 400 kPa (3.6 - 4.0 kgf/sq.cm, 51.2 - 56.9 psi)
b. Start engine and warm it up to normal operating temperature, and measure fuel pressure at idling.
Fuel pressure specification
At specified idle speed: 360 - 400 kPa (3.6 - 4.0 kgf/sq.cm, 51.2 - 56.9 psi)
c. Stop engine, and measure fuel pressure at one minute after stopping.
Fuel pressure specification
With 1 min. after engine (fuel pump) stop (Pressure reduces as time passes):
Over 250 kPa (2.5 kgf/sq.cm, 35.6 psi)
6. After checking fuel pressure, remove fuel pressure gauge.
WARNING: As fuel feed line is still under high fuel pressure, make sure to release fuel pressure according to the following procedures.
^
Place fuel container under joint.
^
Cover joint with rag (1) and loosen joint nut slowly in order to release fuel pressure gradually.
7. Remove special tools from fuel delivery pipe and fuel feed hose.
8. Connect fuel feed hose to fuel delivery pipe and clamp it securely.
9. With engine OFF and ignition switch ON, check for fuel leaks.
