check the wire to the sending unit for nicks / cracks / lacerations maybe it got accidentally nicked during an install or during some work.

do you have or could borrow another fuel gage to swap in? maybe the gauge itself is bad.

I would start by moving the wire around to see if that has an effect on your fuel gauge. I'm sure you've already done that.

Next, I would take a multimeter with me on drives. When the gauge isn't work, check the ohms on the wire that goes to your fuse box. If the ohms look right, then plug the wire back in the fuse box. If the gauge still doesn't work, then the problem probably isn't your sending unit or wire.

Im guessing that you probably know how to use a multimeter, since you just installed a FSU. If not, let me know.

I'm glad that you got it fixed.

I love a good easy fix. Actually, I need an easy fix! Lately, everything that I have been doing has been challenging with little or no results. I've messed with my steering column that wont lock in park for two days with no results. It looks like I will have to buy a new one.
