(9) Disconnect the vacuum hose (blue stripe) from the intake
manifold and plug the nipple. Then measure fuel pressure_
Standard value: 330-370 kPa (3.3-3.5 kg/cm?,
47-53 psi) at curb idle speed
(1O)Check to be sure that the fuel pressure during idling does not
decrease even after the engine is raced a few times
(11)Usea finger to gently press the fuelreturn hose while repeat-
edly racing the engine, and check to be sure that there is fuel
pressure in the return hose also.
NOTE
There will be no fuel pressure in the return hose if there is
insufficient fuel flow:
(12)lf the fuel pressure measured in steps (8) to (11) deviates
from the standard value range, check for the probable cause
by referring to the table below, and then make the appropri-
ate repair:
