hello my name is chris and im new to the site, i have read alot about other problems with the fuel gauges from your experiences. ok when i first start the the car the gauge will go to full and stay there for a couple minutes then will go to empty and will not move until i turn off the ign and turn it back on. so i went to auto zone and the guy told me that alot of poeple have the same problem and its the floater. so i never researched it, so i bought a fuel pump everything new. still did the same thing. i read from your posts that your gauge is wacky its all over but mine wont move only to full then to empty after a couple minutes. so any ideas ? any idead would be helpful. thanks for your support

Did you change the sender unit?

isnt the sending unit on the fuel pump ?

It'* part of the whole unit. This may help.

Do you have any other gauges acting odd? It could also be a ground problem.

yeah i replaced the whole fuel pump. well that and my oil pressure is at 120

You may have some ground corrosion problems Try cleaning all your ground points. There'* some info about that in the tech info area.

i tell ya if thats all it is im gonna kick my self in the a** lol thanks for the help ill try that tomorrow and let ya know how i made out

the only thing i could find so fare is the ground buss connectors, is that what you are talking about or the actual grounds on the body itself ?

Good luck. Post your results.

Yes, that'* what I'm talking about. I don't recall if there'* ground points under the dash on your year.
