Tacoma PreRunner L4-2.7L (3RZ-FE) (2004)
If pressure is not as specified, check the fuel pump, pressure regulator and/or injector.
s. After checking fuel pressure, disconnect the negative (-) terminal cable from the battery and carefully remove the SST to prevent gasoline from
splashing.
SST 09268-45014
t.
Reconnect the fuel inlet pipe to the delivery pipe with 2 new gaskets and the union bolt
Torque: 29 N.m (300 kgf.cm, 22 ft.lbf)
u. Reconnect the negative (-) terminal cable to the battery.
v. Check for fuel leakage.
3. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals 4 and 5.
Resistance: 0.2 - 3.0 Ohm at 20 °C (68 °F)
If the resistance is not specified, replace the fuel pump and/or lead wire.
4. INSPECT FUEL PUMP RESISTANCE
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.
NOTE:
-
These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
