1999-2002 Silverado's

[mcobb2]

I have a 2000 Silverado and the gas gauge is screwed up. Most of the time is says low fuel but as soon as I shift into nuetral it pops back up to the acctual amount. I know my uncles 2001 does the same thing. Just wondering if anyone else has had/ does have this happening.

Mine moves around a little (1/16-1/8) incriments but its pretty damn close to whats in there. If it shows empty almost all the time its probably a fuel sending unit sensor.

Yup, it's the sending unit which is located in the tank on the fuel pump. Mine was terrible, but when I replaced my fuel pump and sending unit, it fixed the problem.

Company work truck is a 99, its screwed up, it either says empty or full nothing in the middle. been that way for a few years now. it stays on full for a while, every so often well driving it goes to empty. A small jerk on the wheel or touch the brakes it goes back to full. we just fill up every 200 miles.

I've been waiting on this thread. I've tried every fuel system cleaner out there and I've seen no change in my truck's ability to detect how much fuel it has.

 

Big question: When I'm not on or pressing the gas pedal, my truck shows empty and my "Low Fuel" light comes on, but as soon as I give it gas it tells me the actual amount of fuel I have. Could this be an indication that my fuel pump is going out or is this just something weird with my sensor?

My old 99 (my sister drives it now) had a great fuel gauge. It always seemed like the first "half" went faster than the second "half" but I don't blame that on the gauge. Also you could get realllllly close to E. It never ran out of fuel, but it was cutting it close at times.

i only voted no because of when i fill up it will move around a little, but after about 10 miles or so its fine and reads correctly from there on out untill the next fill up.

See, mine whenever I start it up it will be "empty" and have the low fuel light on after about 10 miles or so it will slowly build up and then while your driving up the road it will kick back from empty the the acctual then back to empty and so on... The only cure I found was to shift into nuetral for a second or two and it will pop right up the the acctual amount... confusing I know...

That's exactly what mine did. Like I said before, replacing the fuel pump and sending unit fixed the problem.

How much did that sending unit send you back... I don't really care... keeps from others from driving the truck but still would be nice

Not exactly sure. It was the dead of winter, so I didn't feel like dropping the tank myself, and I replaced the fuel pump and sending unit together.

At last! Thought I was the only one having problem. If I fill it up it will say full and then when I stop at a light the gauge will go to E and give me the low fuel light. Does this even though I have half a tank or even a quarter, or sometimes when I start the car it will say low on fuel than gradually go up. So how hard is it to replace the sending unit and fuel pump because I'm having intermit startup problem.

My 2002, knock on wood, has 115K on it and I have had no problems. My cousin's '99 model with 180K has had all sorts of issues. My sister-in-laws '01 model with around 65K has no problems.

[chris_kucia]

Had issues shortly after I bought it (used)

 

Replaced fuel pump and sending unit (at the time, you couldn't buy the sending unit separately - not sure if that's still true).

 

Been working fine for a few years now.

 

 

I lifted the bed to get to the tank at the time. Been giving serious consideration to buying a marine hatch and cutting a hole in the bed above the fuel tank to provide access. Knowing GM, its only a matter of time before the fuel pump goes. With the hatch, I could probably buy a pump and stash it in the cab so when it dies on me, I could replace wherever it dies with a few hand tools.

I had an 01 Sierra that had a screwed up fuel guage. It went back and forth from full to empty.

I have an 08 silverado now, and the guage in that seems inconsistent. I actually ran out of gas pulling into a gas station the other day. it went from just under a quarter tank to empty in about 10 miles. sometimes i'll park it with more than a 1/4 tank, and when i start it up later it only shows an 1/8th of a tank.
