Injector Driver Module

The PCM ﬁ res the injectors with the injector driver module. Because the fuel system

is running at up to 1885 PSI, it requires more energy to open the fuel injectors. The

injector driver module turns the injectors on with +100 volts. The injector is then held

open with +12 volts. The injector driver module then closes the injectors with -100

volts. The injector driver module is located at the rear of the drive strut tower.

High Pressure Fuel Injectors

Removal requires a special tool similar to O

sensor socket, fuel pressure

must be released and intake manifold must be removed. The tool is rocked

left to right to loosen any carbon holding the injector.
