as stated tuners i need some help i just bought a suzuki swift roro and the gas guage won't budge on a full tank the dealer changed the panel and checked the tank to make sure the float is good still no such luck and anyone help me out

had that problem with one ...we dropped the tank and replaced the complete float mechanism.
i have also seen the arm broken off ...... make sure the tank was dropped ... it's the only way to check the float

I had this issue on an old toyota.

I never let the gas run past 3/4 tank, so after 5+ years, it got stuck at 3/4 tank and did not want to move.

Before you go changing any more parts, run the tanks of gas till empty, or as close to empty as you are comfortable with then open the tank and giggle the float mechanism. After doing that a few times, the problem resolved itself (in my case).

The caveat here is that the car is new to you and you are not really familiar with the gas consumption, and in my scenario, the gas tank was accessible via the trunk.....but I suggest you try it before you go around poking around with anything else.

they droped the tank and took out the float thing i saw th guy check something on his meter and it got reading.
he further said it was not the flot of anything so i'm very very confused right about now

well im fresh out of ideas after that

trace the harness is my only other suggestion

the guy said i should take it to a auto electrician to try to trace the wiring you guys know anyone who could handle that type of job

Did he move the float up and down and determine of the output varied?

If not then .....this would only prove that the float wiring is intact and working, it may not ascertain if there is a mechanical problem with the float, then would not show with a meter check.

i actually think the guy moved it up and down when he took it out and grounded it but it did not move

did you check to see if the gauge moved when the guy was moving it up or down?sometimes the lil circuit board gets worn or damaged preventing it from reading
