INSPECT FUEL INJECTOR ASSEMBLY
(a) Inspect injector resistance.
(1) Using an ohmmeter, measure the resistance
between the terminals.
Resistance:
11.6 to 12.4 Ω at 20°C (68°F)
If the resistance is not as specified, replace the
injector.
(b) Inspect the injection volume.
CAUTION:
This test involves high-pressure fuel and
electricity. Take every precaution regarding safe
handling of both the fuel and the electricity.
Perform this test in a safe area, and avoid any
sparks or flames. Do not smoke.
(1) Install the fuel tube connector to SST (hose),
then connect the tube connector to the fuel
pipe (vehicle side).
SST 09268-31011 (09268-41500, 90467-
13001, 95336-08070)
(2) Install the O-ring to the fuel injector.
(3) Connect SST (adaptor and hose) to the
injector, and hold the injector and union with
SST (clamp).

08070), 09268-41140, 09268-41400
(4) Put the injector into the graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector
to contain gasoline spray.
(5) Operate the fuel pump (See page FU-8).
(6) Connect SST (wire) to the injector and the
battery for 15 seconds, and measure the
injection volume with the graduated cylinder.
Test each injector 2 or 3 times.
