    Vibrating Fuel Gauge


    Support FSC and see no ads! - Click Here
    I have noticed the fuel gauge on my 1999 Chevy K1500 Suburban starting to vibrate a lot. I believe it is probably still accurate, but the needle dances around aabout 1/16"-1/8". When I start or turn off the ignition it jumps all around for a few seconds.

    What might cause this? ...is it an easy fix? I figure it's just a matter of time before it goes out completely at this point and it's getting a little noisy.

    Thanks

    Re: Vibrating Fuel Gauge

    My '99 does the same thing it's in the gas gauge it's self,
    i was told you need to send it in to be fixed or find another
    used one..

    if you could find a new stepper motor you couls change
    it out and it would be fixed.

    Re: Vibrating Fuel Gauge

    How long has yours done this? Also, does it still read the fuel level even though it's vibrating, meaning does it still work or should I plan on mine going out?

    What's a stepper motor? ....where is it located and how hard is it to change out?

    Thanks for the reply

    Re: Vibrating Fuel Gauge

    Well i fixed my problem,it was as i described bellow
    it's the gas gauge it's self,i picked one up off
    ebay and checked it with my old one and like i said
    it had no resistance(drag)to the needle when i moved
    it with my finger,i switched over the odometer and
    installed the new cluster and the gauge works
    perfect!!!, so i would suggest you guy's may want to
    do the same.

    somehow the stepper motor that runs that gauge burns
    up and just moves freely and that's why it shakes.

    because they all have this resistance but the gas gauge and
    that's the one that shakes..

    Re: Vibrating Fuel Gauge

    Is there any chance you have checked this place to see if they have anything that might work?

    I am googling Stepper motors but I see what you mean, they are hard to find for this year. I did find some on ebay for an '03-'06, I wonder what the difference is. I guess I need to pull my dash off and write down what it says.

    Re: Vibrating Fuel Gauge

    I have a '99 tahoe which does this, and my buddies '99 Z71 does the same thing. Interesting. I'm subscribing to this tread :).

    Re: Vibrating Fuel Gauge

    My '99 Z71 Tahoe does this as well and has for over a year now. It has done this since I purchased the truck but still registers the correct amount of fuel. It appears to be a known problem with that year and model. ...just another thing I will have to repair on my aging beauty. :)

    My 99 sierra does it as well, the fuel, oil pressure, and battery.

    Re: Vibrating Fuel Gauge

    I had a 98 1500 that did this after about 6 months of ownership(I bought it in 05 with 160k on it).

    One time when I was under it, I saw a black wire with a tab on the end of it hanging beside the fuel tank. It was the ground wire lug had broken off the fuel sending unit. I never did fix it, but it should have been an easy fix...just needed to ground the tank properly.

    Not sure if its the same story on the NBS's or not. My truck just exhibits the damn bad fuel sending unit problems I've read about... Getting annoying and I've only owned the truck for 9 days.

    My 99 Yukon does this too, just thought I'd toss my hat into the ring. Started doing it about two years ago but has registered the correct amount of fuel this whole time. The needle just buzzes.
