Temporarily connect the positive cable
and
negative
cable
to
the battery and fuel pump
5P
connector.
Start the engine and let it idle.
Read the fuel pressure.
STANDARD:
'13 model:
294
kPa (3.0 kgf/cm
2
,
43 psi)
After '13 model: 263 - 316 kPa (2.7 - 3.2 kgf/
cm
2
,38 -
46
psi)
- If the fuel pressure
is
higher than specified, replace
the fuel pump unit (page 7-10).
- If the fuel pressure
is
lower than specified, inspect
the following:
- Fuel line leaking (page 3-6)
- Fuel pump unit (page 7-10)
- Clogged fuel filter (page 7-10)
After inspection, relieve the fuel pressure (page 7-6).
Remove the fuel pressure gauge, attachment and
manifold from the fuel pump.
Connect the fuel pump side quick connect fitting
and
normalize the fuel pressure (page 7-7).
