The fuel level gauge usually shoots right up to the correct fuel level seconds after it is started. Now it doesnt read accurately until I drive off and about a few blocks. It worked fine the night before and all before that.

It could be the gauge, you might not have a good ground...It could be the sender in the gas tank...

You could get a buddy to watch the gauge for you while you ground it to make sure it's working properly...

If you take your gas cap off does it make a huge gasp?...Kinda like how "Darth Vador" breaths...

Well, I was just tryin to eliminate a few things...I dont think its the problem, but if you hear the "gasp" when you pull off the gas cap it means your charcoal canister is working (creating a vacuum) and your gas cap is also holding pressure...

It could be a lot of things...The way to find out what the problem is, is by processes of elimination...

Yeah, what if it never ever did that? I know for sure because only my truck makes that hiss. So, does the fuel system need pressure for the gauge or sending unit to work correctly?

You probably have a bad gas cap...When was the last time you got a smog?...They are supposed to test the cap as part of the smog...It shouldn't make a difference to the gauge though...The gas cap works as a one way valve letting air in and not letting air out...

I still think it's the gauge or the sender...Dont buy anything until you check the gauge....
