| Condition | Probable cause | Remedy |
|---|---|---|
| Fuel pressure is tOo low, | Fuel filter is clogged. | Replace the fuel filter. |
| Malfunction of the valve seat within the tuel pressure regulator, or fuel leakage to return side caused by spring deterioration | Replace the fuel pressure regulator. | |
| Fuel pump low discharge pressure | Replace the fuel pump | |
| Fuel pressure is too high: | The valve within the fuel pressure regulator is sticking | Replace the fuel pressure regulator. |
| Clogging of the fuel return hose ad/or the pipe: | Clean or replace the hose and or pipe |
(9) Disconnect the leadwirefromthe fuel pump activating
terminal (black) tostop the fuelpumpandcheck for
change of the value indicated by the fuel pressure gauge
The conditioniSnormaltherenodecrease ofthe
indicated value within two minutes
If there iSa decrease of the indicated value;monitor the
speedof thedecrease, and, referring to the table below,
determine the cause of the problem and make the appro-
priate repair.

|---|---|---|
| After the fuel pump iS stoed the fel ressre | Injector leakage: | Replace the injector, |
| pp, u pu drops gradually: | Leakage at the fuel pressure regulator valve seat. | Replace the tuel pressure regulator. |
| There is a sudden sharp drop of the fuel pressure immedi- fuel ately after the pump IS stopped | The check valve (within the fuel pump) not closed | Replace the fuel pump |
(1O)Connect a hand vacuum pump to the fuel pressure regu-
lator and apply vacuum of 80 kPa (600 mmHg, 23.6 in.Hg)
to remove allremaining pressure from inside the fuel line
1) Disconnect the fuel pressure gauge ad the special tool
from the delivery pipe.
Caution
Because therewill beslight amount of remaining pressure in the fuel pipe line, use rags to cover s0 that fuel doesn't splatter.
(12) Replace the O-ring at the end of the fuel high-pressure hose
with a new one
(13) After connecting the fuel high-pressure hose to the delivery
pipe, tighten the installation bolt at the specified torque.
Tightening torque:5 Nm (0.5 kgm, 3.6 ft Ibs )
(14) Check to be sure that there is no fuel leakage:
Apply battery voltage to the terminal for activation of the
fuel pump so as t0 activate the fuel pump.
With fuel pressure applied, check for leakage of the fuel
line.
(15) Install the intake air plenum;
