Description

Our expert Duramax FICM repair service restores your 2001–2005 GM 6.6L LB7 or LLY Fuel Injection Control Module, protecting your diesel from unnecessary expense and downtime. Every unit is carefully evaluated, rebuilt with upgraded electrical components, and—exclusive to our process—includes a new OE-spec vent port. This critical update protects the electronics from harmful water entry, a known culprit in circuit board corrosion and unrepairable damage.

You'll keep your truck’s original programming, settings, and driveability—no relearning, coding, or tuning swaps needed. The process is simple: order online, ship your FICM with your invoice and a short symptoms description (injector issues, hard/no start, etc.), and we’ll handle diagnosis, repair, and final testing. If the core is beyond repair (burned, fried, or water-damaged circuitry), we only charge a $150 test fee and refund the difference. Get your diesel back to full operation with our industry-leading lifetime warranty and unmatched quality—trusted by shops and owners nationwide.
