(f) Connect the TOYOTA hand-held tester to the DLC3.
(See step 1 in check fuel pump operation (a) to (e).)
(g) Reconnect the negative (-) terminal cable to the battery.
(h) Turn the ignition switch ON.
(i) Measure the fuel pressure.
Fuel pressure:
226 - 275 kPa (2.3 - 2.8 kgf/cm
2, 33 - 40 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the following parts:
(1) Fuel hoses and connections
(2) Fuel pump
(3) Fuel filter
(4) Fuel pressure regulator
(j) Remove the TOYOTA hand-held tester from the
DLC3.
(k) Start the engine.
(l) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator, and plug the hose end.
(m) Measure the fuel pressure at idle.
Fuel pressure:
226 - 275 kPa (2.3 - 2.8 kgf/cm
2, 33 - 40 psi)
(n) Reconnect the vacuum sensing hose to the fuel pressure
regulator.
(o) Measure the fuel pressure at idle.
Fuel pressure:
167 - 216 kPa (1.7 - 2.2 kgf/cm
2, 24 - 31 psi)
If pressure is not as specified, check the vacuum sensing hose
and fuel pressure regulator.
(p) Stop the engine.
(q) 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.
(r) After checking fuel pressure, disconnect the negative (-)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
SST 09268-45012
(s) Reinstall the fuel inlet hose to the fuel filter with 2 new gas-
kets and the union bolt.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(t) Reconnect the negative (-) terminal cable to the battery.
(u) Check for fuel leaks.

8. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
4 and 5.
Resistance: 0.1 - 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump, lead
wire or fuel pump bracket.
9. INSPECT FUEL PUMP OPERATION
Connect a tester lead from terminal 4 of the connector to the
positive (+) terminal of the battery; connect another tester lead
from terminal 5 of the connector to the negative (-) terminal of
the battery.
NOTICE:
These tests must be performed quickly (within 10 se-
conds) to prevent the coil from burning out.
Keep the fuel pump as far away from the battery as
possible.
Always connect or disconnect at the battery.
If operation is not as specified, replace the fuel pump, lead wire
or fuel pump bracket.
