DIAGNOSTIC SOFTWARE
FFI Diagnostics
If the engine is running, a warning screen will be
displayed and the software will not advance to the
Static Test screen. If this happens, you must press
the "ESCAPE" key to return to the Main Menu, or
shut the engine off. When the engine is shut off,
the Static Test screen will be displayed.
Testing Fuel Injectors
NOTE: Do not start the engine during any stat
ic test. Doing so will cause erratic operation
until you shut off the engine.
Type "1" to test the fuel injectors. The computer
will display a screen prompting you to enter the
number of the injector you want to fire. Type the
number of the injector you want to fire.
The computer will display a screen telling you
which injector is firing and how long it will continue
to fire. The injector will fire approximately once a
second for 5 seconds. The screen counts down
the amount of time to the end of the test. If you
press any key, the injector will stop firing immedi
ately. The screen changes back to the previous
screen when the injector stops firing.
The FFI ™ fuel injector will make an audible click
ing sound each time it's activated. This sound indi
cates the injector is being activated by the EMM
and that the injector armature is moving. You can
also use a timing light connected to either (but not
both) injector leads to see if the injector is being
triggered by the EMM.
If the timing light flashes and the injector clicks, the
injector is most likely functioning as designed. If
the light flashes but the injector does not click, the
injector is probably damaged. If the timing light
does not flash, the problem is probably not in the
injector but in the fuses, wiring, or EMM.
When you are finished testing injectors, type "X" or
press the "ESCAPE" key to return to the Static
Test screen.
NOTE: #1 Injector: MAG
#2 Injector: CTR
#3 Injector: PTO
