​​​​​I got the car with a lot of paperwork for the maintenance it had been done I still have the piece of paper from when fuel gauge first stopped working (I think) the wire that's cobbed is a green wire does anyone know where I can find a wiring diagram to figure out which wire this is to verify that it's a fuel gauge wire and if it is does anyone have any suggestions on what I should do. is changing the cluster pointless?

 

I don't have answers to all your questions, but I'll help you help yourself. First, download selected sections of the FSM (Factory Service Manual) from the 2nd link in my signature (below). You'll need at least the following sections:

• IDX: Index section, here you can look up where to find things. For example, for "Fuel Gauge" it says go to EL-104 (assuming 2000 Maxima).
• GI: Has information on how to read schematics, wire coloring, testing, and many other basics.
• EL: Describes the electrical power distribution and schematics. The description of the Instrument Cluster and associated wiring starts on page EL-104.
• EC: You'll probably also need this section (on Engine Control), it has a lot of important info on troubleshooting and diagnostic code resolution.

Good luck!

 

Maybe I'm dumb but I didn't see anything in your signature I've been looking for FSM for about an hour but Charles and Aubrey was password protected, and niko was forbidden? can can someone please point me in the right direction of a working FSM any and all help would be appreciated it's a 2002 gle

 

The third line from the bottom of maxiiiboy's signature (Get FSM from here: http://boredmder.com/FSMs/Nissan/Maxima/) is a link to service manuals.
It worked when I clicked on it.
