The FICM Fuel Injection Control Module controls the fuel injectors on your 6.0L Powerstroke engine. Overtime the factory control module on your F250, F350, F450, F550 or Excursion can fail resulting in rough running conditions, rough idle, hesitation, or even failure to start. This Injector Power Supply Repair Circuit Board is a direct replacement for the factory board on your 6.0L Powerstroke engine. The module installs directly into your factory FICM Module and requires NO PROGRAMMING or REFLASH. Purchase this module from AA Ignition and save hundreds off the dealer price.
