I’ve been Noticing that when i start my car up it takes 5 to 10 mins for fuel needle to raise slowly from E to remaining fuel point, and whenever i go for a drive the needle slowly goes back to E and Stays there whole time till i stop somewhere. Any answers why it’s happening?

Possibly the tank unit (fuel sender)
May need to check the resistance of the unit with a multimeter at the connector.
Being a VZ, and if its the original unit, there is a good chance its failing, or failed.

Being the gauge is working, and for what its worth, maybe just replace the tank unit.

How do i Check it?, well today with my friend he have a similar issue with his commodore, he said park your car on a slope road leaning to right And when i did it within a minute the fuel gauge showed the remaining fuel it went from E to Above the red line, so it means my Fuel pump is bad?
