Description
Many times, the high-pressure pump is to blame for a low-pressure code or performance issue related to low pressure. Often the technician does a multitude of tests and from those results determines that the high-pressure pump is the fault.
After replacing the high-pressure pump, the vehicle still has issues, only to find out there was another cause of the low pressure. Another concern is, what caused the system to fail? If the high-pressure pump failed the question should be asked, what caused the high pressure to fail? What if the fuel is tested and no contamination is found?
This program will give you the knowledge to understand what influences the high pressure pump to make high pressure, and provides testing procedures that go beyond the manufacturer’s steps.
Course Objectives:
- Identify different types of supply pumps
- How to check the supply system
- How to check the high-pressure pump
- Perform contamination check
- What to replace when contamination is found
- Injector return testing
Runtime: 66 minutes
