Common Symptoms
- Hard start cold (won't fire until restart)
- Rough run on startup then smooths out
- Intermittent misfires
- No start in worst case
- CEL
Probable Causes (Ranked by Likelihood)
- Failed FICM power supply section (48V section degrades over time -- classic 6.0L failure) Very Likely
- Weak batteries (FICM needs >11.5V to maintain 48V output) Likely
- Corroded FICM ground or power connector Possible
Step-by-Step Diagnostic Procedure
Check FICM voltage via scanner PID or by back-probing B+ and B- on top of FICM -- should read ~47-48V. Under 45V = failing; under 40V = no-start.
Load-test BOTH batteries -- weak batteries accelerate FICM power supply failure.
Replace batteries first if they're weak; it can save the FICM.
If FICM voltage is low with good batteries, install a FICM repair (just replaces the power supply board) for $300-$500 or full FICM for $700-$1,200.
