do the injector open with the electrical plus or close with it. if there isn't any pulse will fuel pressure open them. I tried a search, & didn't see what I'm looking for.

Re: injectors
Fuelpressure should NOT open them, then they are bad. They shall always be closed if they not getting a signal to open.

Re: injectors
When the injector is grounded out, it opens: otherwise it is always closed. At least, that is my understanding.
