SYSTEM ANALYSIS FUEL DELIVERY TESTS Results: No injectors actuate: Use the diagnostics software Monitor screen to make sure voltage is present on the system voltage circuit Refer to Running Fuel System Tests on p103Some injectors actuate; some do not: Test the resistance of individual injector circuits between the injector connector and injector control wire at the EMM See Fuel Injector Resistance Test on p147All injectors actuate: Refer to Running Fuel System Tests on p103Results: 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 faulty EMMIrregular or no light activation on some injector wires: Test the resistance of individual injector circuits between the injector connector and injector control wire at the EMM Check battery cable connections Make sure all grounds are clean and tight See Fuel Injector Resistance Test on p147Steady 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 faulty cylinderSee DYNAMIC TESTS on p94
