LLY: Fuel gauge help and programmer

[Mondo0928]

I have a 05 2500 lly duramax crew cab, well when I got the truck the fuel gauge was working great and all then I put fuel in and it was good. Well just the other day my girl said she put fuel well the needle is stuck on and it won't move on the gauge and the edge attitude cts programmer. Please help me I'm new to this forum and it's bothering me because what if I needed to go out of town and I run out of fuel what can be the problem and where can I start? Thank you

Fuel gauge and water-in-filter sensor are unrelated.

There are two wire that go into a reed switch at the bottom of the fuel filter. Short them together and the warning will come on.. jiffy lube may have screwed up the sensor or wireing or there may actually be water in the filter. Inspect the wireing and try draining the filter.
