CLEANFIRE INJECTION (CFI)
Injector Replacement
The Cleanfire system utilizes 3 different color injectors. If you
are replacing an injector you must replace it with the same color
injector you remove.
The color is indicated in three ways, 1) it will be on the short wire
harness that is attached to the injector, 2) the injector will have
a colored dot on the shaft of the injector 3)it is indicated on the
label of the ECU.
If the color injector is not available you may replace all injectors
with a different color and you must program the ECU to run the
new installed color.
If it is verified that an injector needs to be replaced, you must
first find out what injector color is on the unit. You can do this
by checking the decal that is located on the top portion of the
ECU or by the color band that is next to the injector on the
harness.

NOTE: If the injector is on the upper fuel rail, only
the air box needs to be removed to gain access to
the failed injector.
NOTE: If the injector is on the lower fuel rail, engine
removal is necessary for injector access. See “600 /
