Toyota Tundra. Manual — part 2101

l. Measure the fuel pressure at idle.

Fuel pressure: 265 to 304 kPa (2.7 to 3.1 kgf/cm

2

, 38 to 44 psi)

m. Stop the engine.

n. 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 the pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.

o. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and

carefully remove SST to prevent gasoline from splashing.

p. Reinstall the front fuel pipe to the LH delivery pipe (see INSTALLATION ).

q. Reconnect the negative (-) terminal cable to the battery.

r. Check for fuel leaks (refer to "CHECK FUEL PUMP OPERATION AND FUEL LEAK" in ON-

VEHICLE INSPECTION).

If the resistance is not as specified, replace the injector.

c. Reconnect the 8 injector connectors.

5. INSTALL AIR CLEANER HOSE ASSEMBLY (See INSTALLATION )

6. INSTALL THROTTLE BODY COVER SUB-ASSEMBLY (See INSTALLATION )

7. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

NOTE:



Some systems need to be initialized after the cable is reconnected
(see INITIALIZATION ).



After the ignition switch is turned OFF, the navigation system
requires approximately 90 seconds to record various types of
memory and settings. As a result, after turning the ignition switch
OFF, wait 90 seconds or more before disconnecting the cable from
the negative (-) battery terminal.
