25 Use a new O-ring and make sure that the pressure regulator is installed properly on the fuel rail (see illustration).

26 The remainder of refitting is the reverse of removal. On 1.3 litre engines, use new copper washers each side of the banjo fitting.

26 On these engines, the fuel pressure regulator is incorporated into the fuel pump/ level sender unit fitted into the fuel tank. Refer to Section 3 for details.

27 Using a jumper wire, bridge terminals TE1 and E1 of the test connector (see illustration).

28 Start the engine. The engine speed should increase to approximately 1000 to 1200 rpm for five seconds then return to normal idle speed.

a) If the engine speed changes as described, the ISC valve is okay.

b) If the engine speed does not change as described, remove the valve as described below.

29 With the valve removed, reconnect the wiring plug.

30 Turn the ignition on. The valve should move from fully open, to fully closed, then to halfway closed in that order, with a gap of 0.5 seconds between each position. If it does not perform as specified, renew the valve.

assembly are difficult to reach, therefore it is recommended to remove the throttle body so that the new ISC valve assembly can be installed properly.

32 Remove the mounting screws and detach the ISC valve and gasket (see illustrations).

33 If the ISC assembly was renewed, be sure to install the temperature vacuum valve (TVV) from the original assembly into the new unit (if equipped).

34 Refitting of the ISC valve is the reverse of removal. Be sure to use a new gasket when installing the ISC valve.
