Fuel System
F-6
6. DLC terminal F/P and car body (GND ground)
are short connected by jumper.
7. Turn ignition switch “ON” to operate the fuel
pump. Measure maximum pressure of fuel line.
Standard:
380～420kpa (3.9～4.1kgf/cm
2
)
8. Turn off ignition switch and disconnect
jumper.
If the pressure is higher than the standard,
check the pressure regulating valve.
If the pressure is lower than the standard, check
the pressure regulating valve by displacement
method. If the abnormal still exist, replace the
whole fuel pump.
9. Disconnect SST.
Caution
l To avoid damage to quick release connector
or fuel leakage, perform the following
procedure according to “Fuel Tank
Removal Instruction”. (Refer to Fuel Tank
Removal/Installation, Fuel Tank Removal
Instruction.)
10. Connect the fuel feeding hose with the
injection rail.
11. Complete inspection after maintenance”.
(Refer to Inspection after Maintenance)
Fuel Pump Assembly Removal/Installation
1. Remove and install the fuel pump assembly.
(Refer to Fuel Tank Removal/Installation)

Warning:
l Fuel spill and leakage are dangerous for it
can be ignited resulting in serious injuries or
death and damage. To avoid this, be sure not
to damage the sealing surface of the fuel
pump assembly when disassembling and
assembling.
1. Disassemble with sequence indicated in the
figure.
2. Assemble in reversed order of disassembly.
