About This Course

This course is designed to give technicians a clear and practical understanding of modern High-Pressure Common Rail (HPCR) fuel systems - a critical component in today’s diesel engines. Whether you’re new to HPCR systems or looking to reinforce your knowledge, this training will help you develop a strong foundation in both theory and hands-on diagnostics.

You’ll explore the key components and operation of electronically controlled HPCR systems, along with the importance of fuel system cleanliness, safety, and contamination prevention. The course also introduces troubleshooting methods for diagnosing common fuel-related issues, including low fuel rail pressure, and drivability complaints.

The skills and knowledge you gain are directly transferable to real-world scenarios, across a wide variety of makes, models, and industries - giving you the confidence to approach HPCR diagnostics with accuracy and efficiency.
