Injector Nozzles
NOTE:
Do not allow open flame or sparks in area while testing and servicing fuel system components, to avoid possibility of fire or explosion.
- Remove one injector from manifold tube, leaving fuel hose attached to injector. Pull injector straight out. Disconnect high tension cable from terminal 4 of ignition coil to prevent engine from starting.
- Point injector into a glass jar. Have someone operate starter for 15 seconds while you observe spray pattern, which should be steady and cone-shaped.
- Turn ignition switch OFF. Hold injector horizontally. No fuel should drip from injector nozzle. If injector does not perform to specifications, replace it. Repeat test for each injector.
NOTE:
When installing injectors, soak rubber seals in gasoline briefly. Be sure injectors are fully pressed into seat.
