5. Check that there are no fuel leaks after performing
maintenance anywhere on the fuel system.
(a) Using SST, connect terminals + B and FP of the data
link connector 1.
SST 09843±18020
(b) With engine stopped, turn the ignition switch ON.
(c) Pinch the fuel return hose. The pressure in high pres±
sure line will rise to approx. 392 kPa (4kgf/cm2, 57
psi). In this state, check to see that there are no leaks
from any part of the fuel system.
NOTICE: Always pinch the hose. Avoid bending as it may
cause the hose to crack.
(d) Turn the ignition switch OFF.
(9) Remove the SST.

2. CHECK FUEL PRESSURE
(a) Check that the battery voltages is above 12 volts.
(b) Disconnect the negative (±) terminal cable from the
battery.
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±
nected from the battery.
If there is no pressure, check the following parts:
wFusible link
wFuses (AM2 30A, EFI 15A, IGN 7.5A)
wEFI main relay
wFuel pump
wWiring connections (c) Check that there is pressure in the hose from the fuel
filter.
HINT: At this time, you will hear fuel return noise.
(e) Remove the SST.
SST 09843±18020 (d) Turn the ignition switch OFF.

Measure the fuel pressure.
Fuel pressure:
265 ± 304 kPa (2.7 ± 3.1 kgf/cm
, 38 ± 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the following parts:
wFuel hoses and connections
wFuel pump
wFuel filter
wFuel pressure regulator (e) Install the fuel inlet hose and SST (pressure gauge) to
the fuel filter outlet with 3 new gaskets and the union
bolt.
SST 09268±45012
Torque: 29 N±m (300 kgf±cm, 22 ft±lbf)
(f) Wipe off any splattered gasoline.
(g) Reconnect the battery negative (±) cable. (c) Put a suitable container or shop towel under the fuel
filter.
(d) Remove the union bolt and 2 gaskets, and disconnect
the fuel inlet hose from the fuel filter outlet.
HINT: Slowly loosen the union bolt.
(h) Using SST, connect terminals +B and FP of the data
link connector 1.
SST 09843±18020
(i) Turn the ignition switch ON.

2. INSPECT POWER OUTPUT OF MAP SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the vacuum hose on the air intake cham±
ber side.
(c) Connect a voltmeter to terminals PIM and E2 of the
ECM, and measure the output voltage under ambient
atmospheric pressure.
(d) Apply vacuum to the MAP sensor in 13.3 kPa (100
mmHg, 3.94 in.Hg) segments to 66.7 kPa (500 mmHg,
19.69 in.Hg).
(e) Measure the voltage drop from step
(c) above for each
segment.
