Backfeed

Hi everyone. I don't know where to post this question so I just put it here.

I've watched a Paul's lecture (premium, forgot which one) and during the lecture he touch a bit on backfeed, explaining what it is. I've since forgot what it meant and the problem is I don't remember which video I watched. So if anyone can explain what it is, or better yet, guide me to that lecture where he talks about it, is greatly appreciated.

I would also be really thankful if anyone kind enough to explain it to me to provide some pictures to go with the explanation.

Thank you in advance. I love this community!

Electrical current follows the path of least resistance. When the path of least resistance is removed, current will find the NEXT path of least resistance.

In this video , at the 31:00 time mark, ScannerDanner illustrates backfeed, through the fuel pump, to the injector circuit.

In the video, the computer is the path of least resistance. When it was disconnected, the fuel pump became the next path of least resistance.
