having some gauge issues on my 1994 z28, first the fuel gauge is being weird, when the car is turned off it indicates correctly, it idle it shows a little higher, when im on the throttle it indicates over full? also the oil gauge is doing this as well.

next issue is the odometer and trip do not work i try to push the reset for the trip and it wont reset, it is just frozen

next the coolant level light is on but the level is fine?


last the abs and parking break lights are still on, the car has the led spoiler brake light, it was not hooked up and i read that this could be the issue, i hooked up the break light and it works but the abs light is still on, what else should i try.
