(2.87 - 2.93 kgf/cm
2, 40.8 - 41.7 psi)
If pressure is high, replace the fuel pressure regulator.

Fuel hoses and connection
Fuel pump
Fuel filter
Fuel pressure regulator
(k) Remove the TOYOTA hand-held tester from the DLC3.
(l) Reinstall the fuse cover on instrument panel.
(m) Start the engine.
(n) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator.

281 - 287 kPa (2.87 - 2.93 kgf/cm
2, 40.8 - 41.7 psi)
(p) Reconnect the vaccum sensing hose to the fuel pressure
regulator plug the hose end.
(q) Measure the fuel pressure at idle.
Fuel pressure:
226 - 265 kPa (2.3 - 2.6 kgf/cm
2, 33 - 37 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 injector.
(t) After checking fuel pressure, disconnect the negative (-)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.

5. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
2 and 6.
Resistance: 0.2 - 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
6. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 2 of
the connector, and the negative (-) lead to terminal 6. Check
that the fuel pump operates.
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 perform switching at the battery side.
If operation is not as specified, replace the fuel pump or lead
wire.
