SYSTEM ANALYSIS
FUEL DELIVERY TESTS
Results:
No light activation on any injector wires (outboard
cranks and starter turns flywheel):
Check stator input to EMM, CPS operation, and
•
all grounds and wiring connections.
Eliminate all other possibilities to isolate a faulty
•
EMM.
Irregular or no light activation on some injector
wires:
Test the resistance of individual injector circuits
•
between the injector connector and injector con-
trol wire at the EMM.
Check battery cable connections.
•
Make sure all grounds are clean and tight.

Steady light activation on all injector wires and
consistent voltage readings, EMM injector control
function is good:
Use the diagnostics software Dynamic Fuel
•
Test to isolate a faulty cylinder. See DYNAMIC
TESTS on p. 112.
