6) Start engine and warm it up to normal operating tempera-
ture.
7) Measure fuel pressure at idling.
If measured pressure does not satisfy specification, refer to
“Diagnostic Flow Table B-3” in “Engine Diagnosis” section
and check each possibly defective part. Replace if found
defective.
8) After checking fuel pressure, remove fuel pressure gauge.
9) Remove special tools from fuel delivery pipe.
10) Connect fuel feed hose to fuel delivery pipe and clamp it
securely.
11) With engine “OFF” and ignition switch “ON”, check for fuel
leaks.
FUEL PUMP WITH PRESSURE REGULATOR
ON-VEHICLE INSPECTION
1) Remove filler cap and turn ON ignition switch. Then fuel
pump operating sound should be heard from fuel filler for
about 2 seconds and stop. Be sure to reinstall fuel filler cap
after checking.
If above check result is not satisfactory, advance to “Diag-
nostic Flow Table B-2”. CAUTION:
As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following pro-
cedures.
Place fuel container under joint.
Cover joint with rag and loosen joint nut slowly to
release fuel pressure gradually.
CAUTION:
When fuel filler cap is removed in any procedure, work
must be done in a well-ventilated area, keep away from
any open flames and without smoking.
NOTE:
The fuel pressure regulator is the one body with the fuel
pump assembly so individual inspection of it is impossi-
ble.
