Toyota Tundra. Manual — part 2143

c. Push the Techstream main switch ON.

d. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump /

Speed.

e. Check the fuel pump operation.

1. Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel

flowing in the fuel tank can be heard. If there is no sound, check the integration relay, fuel
pump, ECM and wiring connector.

f. Check for fuel leak.

1. Check that there are no fuel leaks after performing maintenance anywhere on the system.

If there are fuel leaks, repair or replace parts as necessary.

2. CHECK FUEL PRESSURE

a. Check that the battery voltage is 11 to 14 V.

b. Perform the "DISCHARGE FUEL SYSTEM PRESSURE" procedures (see FUEL SYSTEM ).

c. Disconnect the cable from the negative (-) battery terminal.

d. Remove the fuel pipe clamp from the fuel tube connector.

e. Pinch and pull the fuel tube (fuel tube connector) to disconnect it.

NOTE:

Do not start the engine.

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.

f. Install SST (pressure gauge) as shown in the illustration.

SST 09268-31011 (90467-13001,95336-08070, 09268-41500, 09268-41120), 09268-45014
(09268-41200, 09268-41220)

CAUTION:



Always read the PRECAUTION before disconnecting the
fuel tube connector (quick type).



The fuel tube may spray fuel as a result of pressure that
remains in it. Do not allow fuel to be sprayed in the engine
compartment.

g. Wipe off any gasoline.

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

i. Operate the fuel pump.

1. Connect the Techstream to the DLC3.

2. Turn the ignition switch ON.

3. Push the Techstream main switch ON.

4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel

Pump / Speed.

j. Measure the fuel pressure.

Standard fuel pressure: 281 to 287 kPa (2.87 to 2.93 kgf/cm

2

, 41 to 42 psi)

If the pressure is higher than the specification, replace the fuel pressure regulator.

If the pressure is lower than the specification, check the fuel hoses and connections, fuel pump, fuel
filter and fuel pressure regulator assembly.

k. Start the engine.

l. Measure the fuel pressure.

Standard fuel pressure: 281 to 287 kPa (2.87 to 2.93 kgf/cm

2

, 41 to 42 psi)

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

m. Stop the engine.

n. Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.

Standard 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 and the fuel tube connector to prevent gasoline from spraying.

p. Reconnect the fuel tube (fuel tube connector).

q. Check for fuel leak.

1. Check that there are no fuel leaks after performing maintenance anywhere on the system.

If there are fuel leaks, repair or replace parts as necessary.
