    Default Fuel Guage bouncing around......

    Just bought a 2000 Silverado... very clean truck, low milage.... all is well except that the fuel guage does not seem to work consistently. When I start the truck, the guage shows empty, the "Low Fuel" indicator lights up in the dash and as I'm driving down the road, the guage starts working on and off...

    Anyone have this problem? Is it the sending unit in the tank? or an electrical issue under the dash? Any thoughts would be appreciated!!!

    is the fuel pump huming loudly. the sending unit for the guage is in the tank. i had a blazer and the guage bounced back and forth from full to empty, a year later the fuel pump went.

    I do hear a little whine from the back of the truck...but nothing major - thought this was normal.

    a little whine is normal but if it starts getting louder it means the pump is going. mine could be herd over the engine right before it went.

    So when you changed the fuel pump, did the guage work properly?

    I have that exact same problem. I have a 2000 silverado also with very low milage (76,000) and my fuel gauge does the same thing. Also if the truck is warm it does not start right away, takes three times for the fuel pump to pressurize because the check valve in the pump lets the pressure drop when you shut the key off. I am waiting for the pump to come into my local parts dealer (they had to order it) will repost if that fixes the prob.
