My car just stopped while idling. sounded like it wasn't

Customer Question

my car just stopped while idling. sounded like it wasn't getting gas. would not start, or start for a second and stop. I've changed the fuel filter and battery. There's no pressure in the fuel line, but a high pitch coming from top driver side of the engine. Is there a relay or something right there, that might be bad? I would hear a switch now an then, as if something was trying to open and allow fuel…
Help…

but i hear what i have stated… and it's taking power to make the noises i'm hearing.
Customer: replied 2 years ago.

Customer: replied 2 years ago.
is there a relay of some kind that might be faulty. it's clearly a high pitch whine.
Expert:  Steve replied 2 years ago.

you said you have the cover off and I assumed you were looking at the item making noise.

Customer: replied 2 years ago.
I can't see the item making the noise. It may be under another cover just above the engine. I only have the big main top cover off.
Customer: replied 2 years ago.
i can't quite tell what's making the noise.
Expert:  Steve replied 2 years ago.

is it an 8 cylinder or 6 cylinder engine?

Expert:  Steve replied 2 years ago.

I am not positive what it could be as I have not encountered this noise on this engine before. I will opt out of your question. please do not rate this question or take any further action until another expert replies, which may take some time, possibly hours

Customer: replied 2 years ago.
but do you have any idea what is connected to the fuel line that could make a noise, that's in that exact area?
