(e)
Install SST (pressure gauge) as shown in the illustration
by using SST and fuel tube connector.
SST
09268–41047 (95336–08070), 09268–45014
(09268–41250)
(f)
Wipe off any splattered gasoline.
(g)
Reconnect the negative (–) terminal cable to the battery.
(h)
Connect the hand–hand tester to the DLC3.
(i)
Measure the fuel pressure regulator.
Fuel pressure:
304 – 343 kPa (3.1 – 3.5 kgf/cm
2
, 44 – 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses and connections, fuel
pump, fuel filter and fuel pressure regulator.
(j)
Disconnect the hand–held tester from the DLC3.
(k)
Start the engine.
(l)
Measure the fuel pressure at idle.
Fuel pressure:
304 – 343 kPa (3.1 – 3.5 kgf/cm
2
, 44 – 50 psi)
(m)
Stop the engine.
(n)
Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:147 kPa (1.5 kgf/cm
2
, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(o)
After checking fuel pressure, disconnect the negative (–)
terminal cable from the battery and carefully remove the
SST and fuel tube connector to prevent gasoline from
splashing.
(p)
Reconnect the No. 1 fuel pipe (fuel tube connector).
CAUTION:
Perform connecting operations of the fuel tube connector
(quick type) after observing the precautions.
2.
CHECK FUEL PUMP OPERATION AND FUEL LEAK
