Fuel Injector: Component Tests and General Diagnostics
INJECTORS INSPECTION
1. INSPECT INJECTOR RESISTANCE
Using an ohmmeter, measure the resistance between the terminals.
Resistance: At 20°C (68°F): Approx. 13.8 ohm
If the resistance is not as specified, replace the injector.
2. INSPECT INJECTOR INJECTION
CAUTION: Keep injector clear of sparks during the test.
(a) Disconnect the fuel inlet pipe from the fuel tube.
(b) Connect SST (attachment and hose) to the fuel tube. SST 09268-41046 (09268-52011)
(c) Connect the fuel return hose. SST (union) and SST (hose) to the fuel pressure regulator. SST 09268-41046 (09268-41091)
(d) Install the O-ring to the injector.
(e) Connect SST (union and hose) to the injector, and hold the injector and union with SST (clamp). SST 09268-41046
(f) Put the injector into the graduated cylinder.
HINT: Install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.
