Hello, I’m not a car person in the least. So my 2008 Malibu, with 95,000 miles, the fuel gauge works then shows empty, then back to full again. This morning as I was parking, gauge was showing empty again, and now my check engine light is on, is this because the fuel gauge is going crazy? So I’m asking, what needs replacing? Is the fuel gauge part of the fuel pump or separate? I know they need to drop the fuel tank, so at that time, I would just want them to fix everything, since the tank is down, is this right? Any suggestions would be greatly appreciated! Thank you all!

Step one is to get a full scan of the systems to see why the check light is on. Many systems are interconnected and can affect each other.
Today's cars are computers on tires so diagnostic scans are a first step in tracking down issues.

Got engine scanned, it’s a bad fuel sensor. How long is it ok to drive like this, before I have to get it fixed? I have a mechanic I trust, but work schedule is a pain and this is my only car. What all has to be replaced?

You don't "need" a fuel gauge to drive. You just risk running out of gas when you don't expect it. It's up to you.

The code doesn't say "bad fuel sensor". It tells you that there is an issue in that system. It could be a wire, a plug, or the float (sensor).\

Until it's inspected, nobody, and especially not an armchair mechanic, can tell you one way or the other. Trust your own mechanic.
