Wiring diagram?

**Minidustdevil22** · 09-23-2015

Are there any electrical wiring diagrams out there for a 2001 grand Prix SE? I'm trying to find out if the reason my fuel gauge isn't working is because of a bad wire.

google search "grand prix fuel gage wiring diagram"

the PCM provides 12V excitation to the level sender on the fuel pump. (C2 pin 69 Purple wire). The sender has a variable resistance transducer as the float moves up and down and is grounded through the black/white wire.

The PCM sends the signal to the gage cluster through C1 pin 3 (orange wire).

so either trace the purple wire from the PCM to the sender. or trace the orange wire from the PCM to the gage cluster. or the cluster is bad.
