Fuel pump wiring help - Toyota Yaris Forums

ATB · 01-03-2016, 02:25 PM

Hello! This is my first post on here and I was seeking some help on my 1999 Yaris. I have been having some misfiring issues and in my seek for the problem I thought I'd check on the fuel pump with filter, but when prying of the metal lid I damaged 1 wire and ripped out 2 more from the connector that attaches on top of the fuel pump. I can't find a picture of what color goes where on the internet and I hoped anyone one here had a clue. A picture would really help me out.

I know this is an old post but, for anyone else.
I'm pretty sure the Black/red is the pumps negative (on mine its pure black), and the white is the positive (Mine is white with a black streak). The pumps wires are also typically a little thicker.

The other 2 are the fuel level for the float inside,
I'm not sure which is which for those 2 but you can always connect those and try the level while not in the tank and find out negative/positive that way for the float.

Actually I think I was wrong, For mine the white/black wire connected to the car body, so that makes it negative/ground. and the black was positive then. lol woops.
