Hey Guys,
It seems like there are quite a few on here that are having a problem with the fuel pumps not priming when turning the key on. I am having the same problem. I have a 1991 Mustang LX. Original V8 car.
Here's the twist, it has to do with wire colors and relay location. Everyone on here seems to have the Pink/Black wire and Blue orange wires going to thier relay (I know there are two other wires I just can't remember what they are). I don't my fuel pump relay has a Black wire with a yellow stripe and a plain red wire going into it(+2 others). This relay is located up front by my mass air meter. Thats one thing.
The other thing is that there is a relay under the seat and guess what, it has a pink/black wire and a blue orange wire going to it. I think that this is the WOT relay for the A/C though. Here's why I think that, I went and got a new fuel pump relay tonight and it fits on the plug up by the mass air meter with the red and black/yellow wires.
Can anyone PLEASE tell me what the hell is going on here ???? I have literally spent this entire past weekend reading through posts on here and haven't found anything.
I would like to find out what wires are what so I can figure out where to start with trouble shooting.
Thanks in advance guys !!!!
