Editing Ford Power Stroke engine (section)

====Electrical and fuel====
Numerous [[engine control unit|PCM]] recalibrations, attempts to "detune" the engine, fuel injector stiction (caused by lack of maintenance and proper oil changes), along with several other drivebility and [[quality control]] problems, have plagued the 6.0. The FICM (fuel injection control module) has been a problem, where low voltage in the vehicle's electrical system due to failing batteries or a low-output [[alternator]] can cause damage to the FICM. In addition, the placement of the FICM on top of the engine subjects it to varying and extreme temperatures and vibrations causing solder joints and components to fail in early build models; mostly in the power supply itself. The FICM multiplies the voltage in the fuel injector circuit from 12 to 48–50 volts to fire the injectors. Low voltage can eventually cause damage to the fuel injectors.
