Tundra 2WD V6-3.4L (5VZ-FE) (2004)
SST 09268-45014
Torque: 34.3 N.m (350 kgf.cm, 25 ft.lbf)
f.
Wipe off any splattered gasoline.
g. Connect a hand-held tester to the DLC3 (See step 1).
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/sq.cm, 38 - 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses, connections, fuel pump, fuel filter and fuel pressure regulator.
k. Disconnect the 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 pressure regulator, and plug the hose end.
o. Measure the fuel pressure at idle.
Fuel pressure: 265 - 304 kPa (2.7 - 3.1 kgf/sq.cm, 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/sq.cm, 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/sq.cm, 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.

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 leaks.
