Ford 6.0L Power Stroke
6.0L hard start & no start
FICM, injection-control pressure, glow plug and fuel-supply testing for 6.0L starting complaints.
Why this matters on the 6.0L Power Stroke
The 6.0L fires HEUI injectors with high-pressure engine oil and a 48V FICM. Weak FICM output, a leaking high-pressure oil system or failed glow plugs are all common no-start causes.
Symptoms owners notice
- Long crank before firing
- No start when hot
- White smoke at cold start
- Stumble until warm
What we check
- FICM output voltage
- ICP rise during crank
- Glow plug and glow plug module resistance
- Fuel pressure at the filter housing
Repair work involved
- FICM repair or replacement
- High-pressure oil leak repair (STC fitting, standpipes, dummy plugs)
- Glow plugs and module
