The car will still run smooth, it's just the precat 02 lambda sensor will need cleaning or changing. Check for any chaffed wires first, it's easier enough to get to. You might just use a bit more fuel than normal. It's not a big job there's a video on YT how to change them

lift the back seat and you will see an inspection cover ,remove the cover and the fuel sender unit is underneath ,most vehicles use a big round plastic ring to hold the sender unit in and you may have to buy a special tool to undo it ,i use a old belt tupe oil filter removal tool where i have extended the belt part with a length of old seat belt ,crude but very effective

How hard is it to change the sender in the gas tank?

It's not really hard, but it can be potentially dangerous. Especially if you don't have a jack to lower the fuel tank. Each tank also has a slightly different locking ring for the sender as well. They're usually not that hard to get apart, but there's potential for sparks and explosions. It's always much easier if you have a nearly empty fuel tank, but keep in mind the fumes are flammable. Usually there are two straps that hold a tank in place. Remove the straps, lower the tank part way, disconnect fuel lines and wires, then lower all the way. Slide the tank out from under the vehicle. Unscrew the locking rings, remove the sender. Make sure the area is clean first, you don't want any dirt getting into the tank. Pull the sending unit out and replace the faulty part. Reinstall exactly as you removed it.

Thinking about buying a 1994 BMW 320i because i've always wanted a BMW, although the head gasket is completely blown and undriveable. What are the chances of me finding a mechanic to do the job on such an...

head gasket repairs will cost you thousands 2 at the least as it involves stripping down half your engine, if the engine starts and you can run the car for more than 40 mins you are in luck, there is this stuff called SEAL UP i think the brand is CARGO you pour it in your radiator and it chemically welds your head gaskets and other cracks back together and lasts for ages and actually works brilliantly assuming the crack isn't to big used it on my car last nite as i had blown head gasket and it runs great now

I have a 2000 GMC 1500 pickup. Can I change the fuel sending unit by itself or should I change the entire fuel module? If I change just the sending unit, will this short out the fuel pump?

I think you'll find sender & pump are all one assy. What is the reason for changing. If it's the gauge, have you removed, cleaned contacts & re-attached wire plug at pump/sender assy, to see if it would cure your problem? Personally, it's not something I'd want to do twice in a short time, so if I was replacing one (if parts are available to do so) I'd replace the other, unless difference in price was extreme.

02 E46 BMW 325I fuel guage

It's very unlikely that changing the spark plugs would cause the fault you describe. In fact I can't see how it could.

Your car may not be using more fuel - it may be that the fuel gauge is giving a false reading of what is in the tank.

I would suspect the fuel sender unit - it's in the fuel tank. The unit is electrically operated via a rheostat - as the float level moves up and down according to the level of fuel in the tank it alters the current - which gives a reading as your fuel gauge.

You should be able to see the electrical connectors of the sender unit on the top of the tank (you may have to remove the rear seat or a panel inside the car - above the tank). Check the wires for cleanliness and security.

If the problem persists ask a workshop for a second opinion. It's not a difficult job changing a sender unit, though I don't know how much one would cost for your vehicle.
