2001 Silversado dash lights

I have a 2001 Silverado and for some reason all the dash lights on come from check engine to the abs light gas gauge goes to empty then back to normal 9 times out of 10 these lights come on . It has done this for a while and doesn't effect how it drives , im possibly wanting to sell it and cant explain to someone that it runs fine with this problem. Where do I start to figure this problem out .

Get a full high end scanner and check dash and body computers for codes and operation.
Post back any codes.

the low fuel and the gas fuel sender indicator are due to the defective in tank sender . this is a 100% GM failure..use some fuel cleaner like techron to reduce the erradic fuel indication. or go for it and get a newlt designed ac delco fuel pump sender assy for about 800 usd that will fix that problem.. the ABS light is normally the front hub assy need be replaced. the bearings rust and then the sensor gets blinded by the rust.

check engine could be many things get code reader with a reset feature they are at the auto store now for 50 USD.. post what code you got then reset the code and we can help ya fix it ..

There wouldn't possibly be a short because all the lights are coming on ? or possibly be the computer

I am very experienced with these issues on my 2000 silverado. the ABS light is what you must get fixed since this can cause you to not be able to stop. many here in the rust belt have these abs issues because the hub bearings rust out after a few years then the abs starts acting up...

as for that low fuel light and the fuel gauge , that is 100% gm failure on these vehicles.. when the fuel pump fails and you replace it , then this will be fixed like I stated before !
