What might be one of the most iconic diesel engines of the last 20 years, the 7.3 Powerstroke was the workhorse that got the job done. Developed to replace the outgoing 7.3l IDI V8 this new version was the first to bear the Power Stroke name. Production of the 7.3 ceased in mid 2003 and was replaced by the 6.0 Powerstroke to meet more strict emission guidelines. In the past few years the 7.3 Powerstroke has seen a bit of resurgence mainly due to the OBS movement. The OBS movement led to a high demand of trucks with these engines no matter what the condition.
The 7.3 was known for its dependability but it did have its fair share of common faults. The fuel injectors/fuel injector wiring, camshaft position sensor and fuel filter housing are among the most common faults with the 7.3.
