DIAGNOSIS
1.
Install the fuel pressure gauge:
^
Refer to steps 1 and 2 on page 11-437 of the 2004-06 TL Service Manual, or
^
Online, enter keyword FUEL PRESSURE, and select Fuel Pressure Test from the list.
2.
Start the engine and let it idle for 2 minutes.
3.
Turn off the engine. Check the fuel pressure gauge. (Pressure should be 380 to 430 kpa [55 to 63 psi].)
4.
Monitor the fuel pressure reading. If the fuel pressure bleeds down quickly after the engine is turned off, go to REPAIR PROCEDURE. If the fuel
pressure does not drop quickly, follow normal troubleshooting procedures for hard starting problems.
NOTE:
There is no specification for fuel pressure bleed rate. Many variables can affect fuel line pressure, such as the fuel pump and fuel injectors. A
bad regulator will lose most of the fuel pressure in the first few minutes after shutting off the engine.
REPAIR PROCEDURE
1.
Relieve the fuel pressure.
