Well I remember someone telling me once that if the guage is pegged, that whatever was going on with it, and if it was bottomed out like on e that this was wrong, and if it was stuck in the middle something else was wrong.

I have no idea what they were now though.


Here's a little insight though, I had one with a broken or bad ground, it stayed on empty and would bounce around alot, when it did work.

Now I went through everything on my monte carlo, because after having the tank out for not getting any fuel I had the ground break off and I riveted it back on. Well after filling it up with some gas it went to half tank, and never moved again. I had it like that for a year, stuck on half tank. I checked everything, took the tank down and re-grounded it to be sure, turns out the fuse blew LOL. Boy did I feel stupid, but I swear when it first happened I checked the fuse. I guess not though because I changed it, and it's worked fine ever since.


So check your fuse first. if that's good then it's probably the ground or plugin. If you can get to them, unplug them and clean them, then plug em back in, if that don't work your guage might be screwed.

Sounds like they got the wrong ohms coming out of them or the guage broke, I say this because I got a temp switch for the old 86 k10 we had, well it had guages, and all they had was one for lights. I put it in, plugged the wire up to it and it stayed pegged past 250 all the time. Soon as I unplugged it, it dropped to the bottom left.

So again unplug them and see if the guage drops. If not guage might be shot.
