Sounds like the 'float' is stuck. This is a small lever in the top of your fuel tank that rests on top of the fuel. When the fuel level drops, so does the 'float' and then it sends a different voltage to the guage, which in turn shows less fuel. It's an easy repair, but requires dropping the fuel tank to get at it. If your not experienced with this procedure, most any repair shop can do it. Try to run out most of your gas first, though, so that you don't 'lose' it at the garage! Good luck. Let me know if you need directions to do it yourself.

Have my car on 3/4 full want to top it up but fuel gauge still showing 3/4 full

Fuel gauge is inaccurate. Just keep filling tank till it takes no more. And knowing the gas mileage you get on the car and fuel tank capacity, set the odometer and when you calculate that you are getting close to the bottom, get some gas.

I have a 2000 3.8 impala that wont take gas and the gas gauge stays full.

Wont take gas and the gas gauge stays full? This question really doesn't make sense. But if you cant put anymore gas in the car and the gauge says full then you have a full tank of gas. If the gauge always says full even when the gas tank is not full then the sender unit is failing or the gauge itself.

99 4runner Fuel Gauge has inaccurate reading

Disconnect and reconnect gauge or you can install an external fuel gauge. You can try checking for blown fuse or ground connection.

I have a 1999 cavalier i don't know what the gas

If the gauge reads full it is not the gas sending unit it is probably a blow fuse, and if you are not sure what you are doing with the ground wire on a gas tank you can blow your head off.
