Gas gauge dont move do they have a seperate fuse for this

Could be a fuse. Have somebody who knows about cars look at the instrument cluster fuse to see if the wire inside is broken.

i dont think there is a seperate fuse for the fuel gauge the only fuses are for the instrument pack if one of these fails other instrument pack functions would be affected also, the usual cause of fuel gauge problems is the sender unit in the fuel tank it is located behind the trim panel forward edge of boot, or a wiring fault,

No. Gauge cluster runs on one fuse

Turn the ignition on and off several times before inspecting the gas tank because a blown fuse is the usual cause for fuel gauge malfunctioning. If the gauge remains motionless, check your fuse box and determine the fuse's location using your service manual.
Replace the fuse if the link is broken or damaged. Then, inspect the gauge's wire connections for cleanliness and make sure the wires are connected.
Turn the ignition switch to the "off" position. Attach one end of a jumper cable to the fuel-gauge terminal behind the gauge itself. Attach the other end to the ignition terminal.
Replace the sender unit in the gas tank if the gauge reads full and your car does not have a full tank. Replace the fuel gauge if the needle remains inoperative.

maybe your fuel sender get access to the tank and see if moving it up makes gauge move

there is no seperate fuse just for gas guage. probably a bad tank sender

Never hurts to check panel light fuse before doing anything else.

there is not a seperate fuse for the Fuel gauge, if the fuse was bad nothing in the dash would work, you have most likely a fuel gauge sending unit problem.

check for blown fuse for gauges,light is a pro blem code,thatll have to be scanned to point at problem area.
