Restore proper fuel injector operation and reliable engine performance with the CARDONE 77-0663 Remanufactured Fuel Injector Control Module (FICM) for 2001-2004 Chevrolet Silverado and GMC Sierra 2500HD/3500 equipped with the 6.6L LB7 Duramax diesel engine.
The Fuel Injector Control Module (FICM) is responsible for controlling injector timing and operation, making it a critical component in the LB7 common rail fuel injection system. A failing FICM can lead to hard starting, rough idle, injector communication faults, reduced power, poor fuel economy, or a no-start condition.
Every CARDONE 77-0663 module is professionally remanufactured to meet or exceed original equipment performance standards. Unlike basic repairs that only replace the power board, CARDONE remanufactures the entire module, re-solders critical electronic connections, replaces common wear components, and performs comprehensive computerized testing to verify proper operation before shipment.
