5) Start the engine.
6) Measure fuel pressure while disconnecting pressure regulator vacuum hose from intake manifold.
Fuel pressure:
Standard; 284 — 314 kPa (2.9 — 3.2 kg/cm2, 41 — 46 psi)
A: INSPECTION
S183656A10
WARNING:
Before removing fuel pressure gauge, release
fuel pressure.
NOTE:
If out of specification, check or replace pressure
regulator and pressure regulator vacuum hose.
1) Release fuel pressure. <Ref. to FU(DOHC TURBO)-50, RELEASING OF FUEL PRESSURE, OPERATION, Fuel.>
2) Open fuel flap lid, and remove fuel filler cap.
7) After connecting pressure regulator vacuum hose, measure fuel pressure.
Fuel pressure:
Standard; 230 — 260 kPa (2.35 — 2.65 kg/cm2, 33 — 38 psi)
3) Disconnect fuel delivery hoses from fuel filter, and connect fuel pressure gauge.
NOTE:
The fuel pressure gauge registers 10 to 20 kPa (0.1 to 0.2 kg/cm2, 1 to 3 psi) higher than standard values during high-altitude operations.
4) Connect connector of fuel pump relay.
