12. ’99-01 models:
Read the pressure gauge (with the fuel pressure
regulator vacuum hose disconnected and clamped).
The pressure should be 300
340 kPa (3.0 3.5
kgf/cm , 43 49 psi).
• If the pressure is OK and engine is running, go to
step 13. If not running, repair the cause, then
continue this test.
• If the pressure is out of spec, go to step 14.
13. ’99-01 models:
With the engine running, reconnect the vacuum
hose and read the gauge again. The pressure
should be 240
300 kPa (2.5 3.0 kgf/cm , 36 43
psi).
• If the fuel pressure is OK, the test is complete. Go
to step 15.
• If the pressure is out of spec, go to step 14.
14. ’99-01 models:
Disconnect the vacuum hose from the pressure
regulator again while you watch the pressure
gauge. The pressure should increase when you
disconnect the hose.
• If the pressure did not increase, replace the fuel
pressure regulator (see page 11-227) and recheck
the fuel pressure.
• If the pressure increased, and all your readings
were within spec, go to step 15.
• If the pressure increased, but your readings were
out of spec, check for these problems:
– If the pressure is too low, check for a clogged
fuel filter and for leaks in the fuel lines.
– If the pressure is too high, check for a pinched
or clogged fuel return hose or line.
– Fuel rail restrictions
15. ’99-01 models:
Reconnect the vacuum hose, remove the pressure
gauge, and reinstall the fuel pulsation damper with
a new washer. Tighten the fuel pulsation damper to
22 N·m (2.2kgf·m, 16 lbf·ft).
NOTE: Disassemble and clean the fuel pressure
gauge attachment thoroughly after use.
16. ’02-04 models:
Read the pressure gauge. The pressure should be
290
330 kPa (2.9 3.4 kgf/cm , 42 48 psi).
• If the pressure is OK and engine is running, the
test is complete. If the engine is not running,
repair the cause, then continue this test.
• If the pressure is too high, check for a pinched or
clogged fuel return hose or line.
• If the pressure is too low, check for a clogged fuel
filter and for leaks in the fuel lines.
• If the pressure is out of spec and the fuel lines are
OK, replace the pressure regulator
(see page 11-228).
17. ’02-04 models:
Remove the pressure gauge, and reinstall the fuel
pulsation damper with a new washer. Tighten the
fuel pulsation damper to 22 N·m (2.2kgf·m, 16 lbf·ft).
NOTE: Disassemble and clean the fuel pressure
gauge attachment thoroughly after use.
