(f) Connect a LEXUS hand±held tester to the DLC3.
(See step 1 in check fuel pump operation (a) to (e))
(g) Measure the fuel pressure.
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.
(h) Disconnect the LEXUS hand±held tester from the DLC3.
(i) Start the engine.
(j) Measure the fuel pressure at idle.
Fuel pressure:
304 ± 343 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
(k) Stop the engine.
(l) 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.
(m) After checking fuel pressure, disconnect the negative (±)
terminal cable from the battery and carefully remove SST
to prevent gasoline from splashing.
SST 09268±45014
(n) Reconnect the fuel inlet hose to the fuel pipe support with
2 new gaskets and the union bolt.
Torque: 29 N´m (300 kgf´cm, 21 ft´lbf)
(o) Reconnect the negative (±) terminal cable to the battery.
(p) Check for fuel leaks.
3. INSPECT FUEL PUMP
(a) Remove the rear seat cushion.
(b) Remove the 3 cap nuts and floor service hole cover.
(c) Disconnect the fuel pump & sender gauge connector.
(d) Using an ohmmeter, measure the resistance between ter-
minals 4 and 5.
Resistance: 0.2 ± 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
(e) Inspect the fuel pump operation.
Connect the positive (+) lead from the battery to terminal
4 of the connector, and the negative (±) lead to terminal
5. Check that the fuel pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.

Keep the fuel pump as far away from the battery as
possible.

Always do the switching at the battery side.

(f) Temporarily tighten the terminal nuts.
(g) Tighten the terminal nut
(1) Put a wooden block on the contact plate and press
it down with a hand press.
Dimensions of wooden block:
20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)
NOTICE:

Check the diameter of the hand press ram. Then
calculate the gauge pressure of the press when
981 N (100 kgf, 221 lbf) of force is applied.
Gauge pressure:

If the contact plate is not pressed down with the spe-
cified pressure, the contact plate may tilt due to coil
deformation or the tightening of the nut.
(2) Using SST, tighten the nuts to the specified torque.
SST 09810±38140
Torque: 17 N´m (173 kgf´cm, 13 ft´lbf)
NOTICE:
If the nut is over tightened, it may cause cracks on the in-
side of the insulator.

(h) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
8,336 kPa (85 kgf/cm
2, 1,209 psi)
NOTICE:

Do not keep the valve closed for more than 10 se-
conds.

Do not let the fluid temperature become too high.
(i) With the engine idling, open the valve fully.
(j) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
Difference fluid pressure:
490 kPa (5 kgf/cm
2, 71 psi) or less
NOTICE:
Do not turn the steering wheel.
(k) With the engine idling and valve fully opened, turn the
steering wheel to full lock.
Minimum fluid pressure:
8,336 kPa (85 kgf/cm
2, 1,209 psi)
NOTICE:

Do not maintain lock position for more than 10 se-
conds.

Do not let the fluid temperature become too high.
(l) Disconnect the SST.
(m) Connect the pressure feed tube.
