(k) Turn the ignition switch ON.
(1) Measure the fuel pressure.
Fuel pressure: 265–304 kPa
(2.7–3.1 kgf/cm
2
, 38–44 psi)
If high, replace the pressure regulator.
If low, check the following parts:
• Fuel hoses and connections
• Fuel pump
• Fuel filter
• Pressure regulator
(m) Remove SST from the DLC1.
(n) Start the engine.
(o) Disconnect the vacuum hose from the pressure reg–
ulator and plug it closed.
(p) Measure the fuel pressure at idling.
Fuel pressure: 265–304 kPa
(2.7–3.1 kg f/cm
2
, 38–44 psi)
(q) Reconnect the vacuum hose to the pressure regulator.
(r) Measure the fuel pressure at idling.
Fuel pressure: 226–265 kPa
(2.3–2.6 kgf/cm
2
, 33–37 psi)
If not within the specified pressure, check the vacuum
hose and pressure regulator.
(s) Stop the engine. Check that the fuel pressure remains
above 147 kPa (1.5 kgf/cm
2
, 21 psi) for 5 minutes
after the engine is turned off.
(g) Install a gasket, SST, another gasket and union bolt to
the delivery pipe as shown in the illustration.
SST 09268–45012
(h) Wipe off any splattered gasoline.
(i) Reconnect the battery negative terminal.
(j) Using SST, connect terminals Fp and +B of the DLC1.
