How the Multiport Fuel Injection System works by Howstuffinmycarworks

This video explains how the Multi-Port Fuel Injection System works.
The video is presented in a simple, easy to understand manner, it focuses on the Fuel Delivery part of the Multi-Port Injection by explaining the parts involved and how each one functions.
By understanding the mechanical side of the Multi-Port Fuel Injection System it is easy to later understand how the Sensors involved play a role in modifying the amount of Fuel that is delivered to each Cylinder either increasing or decreasing the Pulse-Width for each Fuel Injector.

Great explanation. I got a 1992 chrysler lebaron with starting problems and suspect the fuel pump, troubleshooting now and very good to know how to check the fuel regulator by pinching the return line! Many thanks
