Cost to Replace a FICM on a 6.0L Power Stroke

The fuel injection control module (FICM) on the 6.0L Power Stroke generates the high voltage that fires the HEUI injectors. When it weakens, you get hard cold starts, a rough misfiring idle, low power, and sometimes a no-start. The FICM is one of the 6.0L's known weak points, and because it is a Power Stroke, this module is specific to the 6.0L and 7.3L architecture; Cummins and Duramax engines do not use a FICM. Replacement or repair cost varies with the route you choose, so use the guidance below as general direction.

What drives the cost

• Your chosen route: a new module, a remanufactured module, a repair or reflash of your existing unit, or a rebuilt board.
• Whether the module needs programming or calibration for your truck.
• Labor, which is usually modest since the FICM is accessible, though the choice of route matters more than access here.
• Related diagnosis, since weak batteries and connections can mimic or contribute to FICM symptoms.

Test before you buy

The FICM has a measurable output voltage, and testing it is the key step before spending. A healthy FICM produces a specified voltage under load; a weak one sags below spec and causes the classic hard-start and rough-idle symptoms. Check FICM voltage with a scan tool or at the module per the correct procedure, and verify both batteries are strong first, because low system voltage makes a healthy FICM look bad. This simple test tells you whether the module truly needs attention.

Repair, reman, or new

The 6.0L FICM gives you options that affect cost:

• A repair or board rebuild of your existing module can restore proper voltage at a lower cost than a new unit.
• A remanufactured module offers a balance of cost and reliability.
• A new module offers maximum longevity but the highest price.
• Whichever route, confirm the correct calibration for your truck.

Get the electrical foundation right

Because the FICM depends on strong system voltage, do not replace it while ignoring weak batteries or corroded cables and grounds. Load-test both batteries, clean every connection, and confirm charging voltage is healthy. A new or repaired FICM installed on a weak electrical system will still struggle. With good batteries, clean grounds, and a FICM putting out the correct voltage, cold starts and idle quality should return to normal.

Frequently asked questions

What are the symptoms of a failing 6.0L FICM?

Hard cold starts, a rough misfiring idle especially when cold, low power, and sometimes a no-start. A FICM voltage test confirms it.

Do Cummins or Duramax engines have a FICM?

No. The FICM is specific to the 6.0L and 7.3L Power Stroke HEUI architecture. Other platforms use different injection controls.

Can I repair my FICM instead of replacing it?

Often yes. A board repair or rebuild can restore proper voltage for less than a new module. Test the FICM and batteries first. Need a FICM or help sourcing one? Email sales@coredieselparts.com.
