13. lnstall and tighten the retainer nuts.
14. Connect the vacuum hoses and fuel return hose to the fuel pressure regulator.
15. Connect the PCV valve.
16. Connect the connectors to the fuel injectors, the IAT sensor ('97 - 98 models), and the EVAP purge control solenoid
valve {'97 - 98 models).
Coat a new O-ring with clean engine oil, and install the resonator chamber ('99 - 00 models).
Turn the ignition switch ON (ll), but do not operate the starter. After the fuel pump runs for approximately two seconds,
the fuef pressure in the fuel line rises. Repeat this two or three times, then check whether there is any fuel leakage.

Reconnect the vacuum hose to the fuel pressure
regulalor.
Check that the fuel pressure rises when the vacuum
hose from the fuel pressure regulator is disconnect-
ed agarn.
lf the fuel pressure did not rise, replace the fuel
pressure regulator.

Replacement
'1. Place a shop towel under the fuel pressure regula-
tor, then relieve fuel pressure (see page 11-1781.
2. Disconnect the vacuum hose and fuel return hose.
3. Remove the two 6 mm retainer bolts and the fuel
pressure reguralor.
