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.
Do you
have the same problem?

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.
