Can anyone tell what may be the problem when the fuel gauge reads full all the time?

Thanks

You're probably gonna' have to pull the pump / sending unit, to test the float arm.

It can be pulled withOUT removing the tank. No special tools needed, except torx drive sockets for the filler neck bracket.
