(2) Switch on the ignition but do not start the engine.
(3) Catch the fuel return hose (See Fig 221) and the pressure in the high-pressure fuel pipe will ascend to about 392KPa.
Check whether there is any fuel leakage under the pressure. Note: avoid its bending when pinching the hose because this
will lead to hose bursting.
(4) Switch off the ignition and remove the special wire for maintenance from the check connector.
Examining fuel pressure on the car:
(1) Check whether the battery’s voltage is 11V or above.
(2) Remove the cable of its negative pole from it.
(3) Dismount the connection bolt and the two washers, and
remove the fuel inlet hose from the fuel delivery pipe. Note:
slowly unscrew the connection bolt after placing an appropri-
ate towel or container under the fuel delivery pipe.
(4) Install the fuel inlet hose and a special pressure meter onto
the transmission pipe with three washers and a special
connection bolt (See Fig. 222). The fastening torque is 29 N.m.
(5) Wipe off the splashed fuel.
(6) Connect the cable for the battery’s negative pole to it.
(7) Connect the terB and FP of the check connector
with a special wire (See Fig. 220).
(8) Switch on the ignition but do not start the engine.
