I removed the five-wire plug and three of the wires red, black and pink I think are not connected. I need to know where the five wires go in the tank plug.

Hello!

I’ve attached diagrams for the fuel pump motor and sender unit (below).

I don't see a pink wire at the connector. Is it possible it could be faded red?

It seems like the wiring order could be:

1. Blue with orange stripe
2. Blue
3. Black
4. Red
5. Black

Please feel free to attach a photo of your connector and wires.

Hi Wendy, the fuel pump went great. I got it wired back up, but I have a problem with intermittent rough running and hard starting. Two times in the last couple of weeks it has conked out on me, and I got it started back and it was running really rough like it was missing on one cylinder then after a few minutes of high idle and revving it up the miss went away it started idling smoothly and running good. now it's happened again after about 2 or 3 weeks. so, I'm wondering if there is a computer or spark or stuck injector. the OBD will not give codes to a reader, and it doesn't look like there's a fuse for the OBD. Any help would be much appreciated.
