I found that there are 4 of these connectors... when I remove one of them, the engines stalls, however there is one which if I remove does not have any effect on the engine so I believe there is no electricity flowing through it.
A shop told me that it wa a "Fuel pump injector" and that I needed a new connector. Im having a hard time finding one, but at the same time, I would like to ask if you guys have seen anything like it, and if that is really the name of this part.
