Hello, first timer here. I have a 2007 ram 1500 4x4. The code says bad fuel pump. But before I drop the fuel tank I have seen some people with the relay that is soldered into the TIPM go out, which is only $10 if you have the right soldering skills. I am trying to figure out the two wire colors that go to the fuel pump so I can see if it is getting power before I spend the 2 days replacing the fuel pump. I have a Haynes repair manual but the wiring diagram does not include the fuel pump circuit at all. Does anyone know the wire colors or have a wiring diagram for a 2007?
I actually asked chatgpt and it said Green with white strip but I am to nervous encase it is wrong. Thank you in advance!

 

You can rent a fuel pressure test gauge for free (when you return it) at any auto parts store. Hook it up to the fuel rail and not only will you see if it's working at all, you can also see if it's working well enough to provide acceptable pressure.

 

oh I already know there is not fuel in the lines, and the fuel pump is not turning on. I am trying to figure out if it is the sending unit, or the pump just went bad.

 

For a 2007, I can guarantee you that it's the fuel pump, but I appreciate that you want to troubleshoot.
I show the white and green wires as correct.
You will ultimately need to lower the fuel tank to get a good test at the plug. You won't need to disconnect the drive shaft.
Let us know if you want some assist if you change the fuel pump. It's not a difficult task and can be done in an afternoon.
