(FICM) Fuel Injector Control Module

Older vehicles didn’t have fuel injection or turbochargers. A carburetor drew air into the engine, mixed it with fuel at a preset ratio, and that was that. However, modern systems tend to use turbochargers as they’re more efficient and allow an engine to produce far more power than a block with a carburetor is capable of. Turbochargers are great at forcing oxygen-rich air into the engine, but a separate fuel injection system is needed to get gas or diesel into the engine’s cylinders. You also need a fuel injection control module, like the 6.0 Powerstroke FICM in your Ford truck, to regulate exactly how much fuel is being injected into the engine. Like all parts, your 2003 6.0 Powerstroke FICM will eventually fail. Even if the part is still going strong, close to 20 years have passed since the 2003 model hit the market, with the 2004 6.0 Powerstroke FICM and the 2005 6.0 Powerstroke FICM not being much younger. With fuel injection being so important, it might be time to consider a 6.0 Powerstroke FICM upgrade. The Ford 6.0 FICM relay is one of those parts that is easy to overlook. Unfortunately, overlooking the 6.0 Powerstroke FICM relay is a pretty big mistake. The part is responsible for transferring amperage from your Ford Powerstroke’s charging system to its FICM, and if it fails, you may end up having to replace an expensive control module instead of a relatively cheap FICM relay 6.0 Powerstroke part. Manufacturers tend to recommend you replace the FICM relay every 100,000 miles.
