Hey internet,

Back again for help because I have some piece of **** wiring in this car that was causing crank, no start. I have traced it back to being the wiring at the fuel tank, take a look at this fine display.

Anyway if I play with these wires enough the car starts again, no **** hey.

I don't know how, but the yel/white does have 7v and I am assuming the blk/white is a ground?
I am not even sure what the other wires are for, I am guessing the fuel level gauge, which also doesn't work? Looks like the other 2 are black and yellow/blk(is the brown wire spliced into the connector). With a red wire being spliced into the brown that leads to nowhere.

I am trying to figure out what I would need to fix this correctly?

Or

Should I just chop the connector and just solder the yel/white and blk/white?

 

at that connector you should have (4) wires - yellow/black power to fuel pump, black ground for fuel pump, yellow/white signal from fuel gauge sending unit and black/white ground for fuel gauge sending unit

 

The fuel pump must be wired up somewhere else as when I disconnect this connector the fuel pump stays on, only the fuel gauge moves a little more to empty.

I was watching a youtube video of a dude replacing the fuel tank and he mentioned something autozone having the wrong fuel pump filter bag and this can cause issues with the fuel gauge not getting off empty or past half way? Anyway can confirm this as sounds like my issue.

Youtube video below in case anyone else needs it.


Off topic but I recommend subbing to this guy heaps of good content.

 

Black/white is power. Yellow/black is fuel gauge
