(e) Install SST (pressure gauge) to the delivery pipe with the
2 gaskets and SST (union and union bolt).
SST 09268−45012
Torque:34.3 N·m (350 kgf·cm, 25 ft·lbf)
(f) Wipe off any splattered gasoline.
(g) Connect the TOYOTA hand−held tester to the DLC3.
(See on−vehicle inspection in fuel pump)
(h) Reconnect the negative (−) terminal cable to the battery.
(i) Turn the ignition switch ON.
(j) Measure the fuel pressure.
Fuel pressure:
265 − 304 kPa (2.7 − 3.1 kgf/cm
2, 38 − 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check these parts:
Fuel hoses and connections
Fuel pump
Fuel filter
Fuel pressure regulator
VSV for fuel pressure control
(k) Disconnect the TOYOTA hand−held tester from the
DLC3.
(l) Reinstall the No.2 timing belt cover with the 6 bolts.
(m) Start the engine.
(n) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator, and plug the hose end.
(o) Measure the fuel pressure at idle.
Fuel pressure:
265 − 304 kPa (2.7 − 3.1 kgf/cm
2, 38 − 44 psi)
(p) Reconnect the vacuum sensing hose to the fuel
pressure regulator.
(q) Measure the fuel pressure at idle.
Fuel pressure:
226 − 265 kPa (2.3 − 2.7 kgf/cm
2, 33 − 38 psi)
If pressure is not as specified, check the vacuum sensing hose
and fuel pressure regulator.
(r) Stop the engine.
(s) 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.
(t) 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
(u) Remove the other union bolt, 3 gaskets and fuel pipe
from the delivery pipes.

(v) Reinstall the fuel pipe with 4 new gaskets and the 2 union
bolts.
Torque:34.3 N·m (350 kgf·cm, 25 ft·lbf)
(w) Reconnect the negative (−) terminal cable to the battery.
(x) Check for fuel leakage.

REMOVAL
CAUTION:
Do not smoke or work near an open flame when working on
the fuel pump.
1. REMOVE FUEL TANK
HINT:
Check for fuel leakage.
2. REMOVE FUEL PUMP BRACKET ASSEMBLY FROM
FUEL TANK
(a) Disconnect the fuel pump connector from the clamp.
(b) Remove the 7 bolts.
Torque: 3.9 N·m (40 kgf·cm, 35 in.·lbf)
(c) Pull out the pump bracket assembly.
(d) Remove the gasket from the pump bracket.
HINT:
Install a new gasket to the pump bracket.

DISASSEMBLY
1. REMOVE FUEL PUMP FROM FUEL PUMP BRACKET
(a) Disconnect the fuel pump connector.
(b) Pull off the lower side of the fuel pump from the pump
bracket.
(c) Disconnect the fuel hose from the fuel pump, and remove
the fuel pump.
(d) Remove the rubber cushion from the fuel pump.
2. REMOVE FUEL PUMP FILTER FROM FUEL PUMP
(a) Using a small screwdriver, remove the clip.
HINT:

INSPECTION
1. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump and/
or set plate.
2. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 1 of
the connector, and the negative (−) lead to terminal 2. Check
that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds) to
prevent the coil from burning out.Keep the fuel pump as far
away from the battery as possible.Always do switching at
the battery side.
If operation is not as specified, replace the fuel pump and/or
plate.
