5) Check fuel pressure as follows.
[Not using SUZUKI scan tool]
a) Turn ignition switch ON to operate fuel pump and after 2 seconds
turn it OFF. Repeat this 3 or 4 times and then check fuel pres-
sure.
b) Start engine and warm it up to normal operating temperature.
c) Measure fuel pressure at idling.
If measured pressure doesn’t satisfy specification, refer to
“Diagnostic Flow Table B-3” in “Engine Diagnosis” section and
check each possibly defective part. Replace if found defective.
d) After checking fuel pressure, remove fuel pressure gauge.
CAUTION:
As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following pro-
cedures.
D Place fuel container under joint.
D Cover joint with rag and loosen joint nut slowly to re-
lease fuel pressure gradually.
e) Remove special tools from fuel delivery pipe.
f) Connect fuel feed hose to fuel delivery pipe and clamp it secure-
ly.
g) With engine OFF and ignition switch ON, check for fuel leaks.
