On the Ford® 6.0L Power Stroke® engine, the Fuel Injection Control Module (FICM) supplies 48 volts to the two injector solenoids. A voltage drop will lead to improper oil flow regulation and fuel injector function.
During cold starts, when oil is thickest, the injector solenoids draw more current. The excessive current draw can damage the FICM’s capacitors, causing them to drop out and lower the voltage supply. A common symptom is rough running on cold startups followed by normal engine operation. Although truck owners often tolerate the condition, it may lead to injector damage and even a crank no-start.
To help prevent serious damage to engines, we’re proud to offer a line of Diesel Fuel Injection Control Modules (FICM) with 100% new, upgraded power supply boards. Featuring a re-engineered layout, our FICM power supply distributes heat more evenly, keeping diodes and other critical components cooler and preventing the failure that can occur in competitors’ units.
The FICM contains two modules: a power module and a logic module. On select Ford trucks, the low-quality electronics on the OE and other aftermarket FICM power modules can overheat and lead to failure. Another common cause of failure with OE units is vibration.
Designed from the ground up at our state-of-the-art manufacturing facility, our Fuel Injection Control Module (FICM) surpasses its counterparts in quality.

... and Make Sure Glow Plugs Aren't the Problem:
FICMs and glow plugs can both cause hard start or rough running on a cold engine. Here's one way to tell the difference:
