Was no fuel pressure applied in Step 1?
Go to Step 8.
Go to Step 9.
(Low pressure is mea-
sured.)
8
With fuel pump operated and fuel return hose
blocked by pinching it, is fuel pressure applied?
Faulty fuel pressure regu-
lator.
Shortage of fuel or fuel
pump or its circuit defec-
tive (Refer to Table B-1
“Fuel Pump Circuit
Inspection”).

1) Operate fuel pump.
2) With fuel return hose blocked by pinching it,
check fuel pressure.
Is it 450 kPa (4.5 kg/cm
2
, 64.0 psi) or more?
Faulty fuel pressure regu-
lator.
Clogged fuel filter,
restricted fuel feed hose
or pipe, faulty fuel pump
or fuel leakage from hose
connection in fuel tank.

1) Disconnect fuel return hose from fuel pipe
and connect new hose to it.
2) Put the other end of new return hose into
approved gasoline container.
3) Check again if specified fuel pressure is
retained.
While doing so, does fuel come out return
hose?
Faulty fuel pressure regu-
lator.
Fuel leakage from injec-
tor, faulty fuel pump (faulty
check valve in fuel pump)
or fuel leakage from fuel
pressure regulator dia-
phragm.
