Full Answer

The problems that are associated with the Ford 6.0 diesel power stroke engine can take hours to diagnose by an experienced diesel technician using a Ford IDS scan tool. The list of issues below offer some insight as to what to look for when diagnosing the truck without a professional mechanic.

Fuel injection control module

The FICM supplies 48 volts to the injectors through a computer and when it fails, the problem is a hard start or no start. Other issues could be a rough idle or even a loss in power.

ERG cooler

When the ERG cooler fails, coolant enters into the manifold causing white smoke from the tail pipe and a loss of coolant in the engine. The problem can cause severe engine damage, including hydro-lock and bent connecting rods.

Turbo charger

The turbo charge issue can be minimal, such as having a buildup of carbon or rust which causes there to be no boost, or severe, where a bearing failure sends sharp shrapnel towards and into the cylinders, which can cause severe damage to the engine.

ERG valve

A failed ERG valve causes black smoke, no start issues, loss of power and sometimes a fluttering noise.

Fuel injectors

Dirty oil, the FICM, electrical problems or other mechanical issues can cause problems with the fuel injectors. A rough idle, hard start and dark smoke are signs of bad fuel injectors and, even though the problem goes away with a warm engine, it can still cause serious damage to the engine if ignored.
