I have a 2006 G35 Sedan and at first my fuel gauge started sticking, then my check engine light on with a Fuel Level Sensor Circuit Low Input code. So I ordered and replaced both fuel sending units. The check engine light went off and they gauge worked properly for a week, then I refilled my tank and I'm back to where I started, check engine light and a stuck fuel gauge. I went back in and verified that the float arms are, well, floating... and I don't see anything else obstructing the units. Is there anything else I can try?

Did you follow the troubleshooting steps in the FSM?

I actually did the work before I found this forum and was unaware of this document. I followed a video on changing the fuel pump and gleamed what I needed there. I'll go through the document and see where I made a mistake.

Thanks
