Individual Injector - Resistance Checking
INJECTOR RESISTANCE CHECK (OFF VEHICLE)
Check resistance between terminals on individual injectors, as shown in figure.
RESISTANCE......approx. 12 - 16 ohms
If resistance is not within the specified range, replace injector(s).
INJECTOR SPRAY PATTERN AND LEAKAGE CHECKING
NOTE: Before opening any fuel hose connection, relieve fuel system pressure by starting engine with fuel pump relay (circuit open relay) disconnected
and let run until engine dies, then slowly and carefully remove hose on outlet side of fuel filter. Cover with a clean rag while removing hose, to
avoid spraying fuel in your face.
1.
Remove intake manifold dynamic chamber and fuel rail with injectors. Leave fuel lines connected.
Leak Checking Fuel Injectors
2.
Secure injectors to fuel rail with wire, making certain that injectors are straight and cannot move (see illustration).
Fuel Pump Test Connector
3.
Energize fuel pump by bridging the terminals of the yellow 2 pin test connector (connector EM14) and turning the ignition "ON" (connector is
located near the air cleaner box). See illustration
4.
One at a time, place nozzle end of each injector into a suitable container, and energize injector momentarily by applying power and ground while
observing the spray pattern.
