alec_b Posted February 7, 2010 Report Share Posted February 7, 2010 Is there any particular reason why mine doesn't work? Actually, it DOES work, as it lights up when I start the car, but it never comes on when I get low on fuel. In my SSEi, it would come on right about when the needle hit the yellow hash marks. I've had the GP waaaay deep into the yellow, no light. However, one night I put gas in it and left it running (damn Minnesota winters), and when I got back in the light was on! Stayed on just long enough for me to realize what it was and BLINK gone just like that. Haven't seen it since. Any thoughts on what might cause this? Bad connection on the IPC board? When do your low fuel lights usually come on? Quote Link to comment Share on other sites More sharing options...

jake91 Posted February 7, 2010 Report Share Posted February 7, 2010 captain obvious to the rescue LOL mine comes on at 1/8 is that where the yellow is? have you ever ran it onto the red? Quote Link to comment Share on other sites More sharing options...
alec_b Posted February 7, 2010 Author Report Share Posted February 7, 2010 No red on my gauge, just yellow. Yellow would start at approx. the 1/8th mark, but I know for sure my gauge it off. I've had it almost to the bottom of the gauge (bottom of the yellow, near the white extreme bottom line), and it only took 14.something gallons to fill it, meaning I had about 1.5-2 gallons left.

Twenty Posted February 7, 2010 Report Share Posted February 7, 2010 My fuel light-heck, all of my warning lights-eventually got a mind of their own. My dealership had to rebuild my cluster and they've been fine since. I don't know an exact cause, but as far as I know it's common for the clusters to go screwy.

spiderw31 Posted February 7, 2010 Report Share Posted February 7, 2010 Any thoughts on what might cause this? Bad connection on the IPC board? When do your low fuel lights usually come on? Mine will come on a little before the needle is in the yellow. However, when I fill the tank (and I don't mean top it off for all its worth), the needle is well above the full mark. Also, if I fill the tank at about the 1/4 mark or a little below, it will take about 13 gallons or so. I wonder if your needle will drop below the empty mark substantially before you actually run out of fuel. If the gauge reads low all the time, that might be why the light doesn't come on.

alec_b Posted February 7, 2010 Author Report Share Posted February 7, 2010 I know the gauge reads low, but only when it's under a half tank. Above a half tank it's pretty damn even, but by the time it gets to the bottom I think it's closer, within a gallon or so. Of course no gas gauge is perfect, especially not GM ones, so maybe I'll just have to live w/o the light. No big deal, I watch my gauges like a hawk anyways.

spiderw31 Posted February 7, 2010 Report Share Posted February 7, 2010 Carry a couple gallons of gas with you, and run her dry once, and you'll know for sure where empty is! Probably wouldn't seriously recommend doing that though (at least not more than once). Bad for the fuel pump, and not really the smartest / safest thing to do either.

alec_b Posted February 7, 2010 Author Report Share Posted February 7, 2010 Yea I don't plan on doing that, don't feel like dropping the tank to do the fuel pump. I had that problem with my aurora, luckily those had an access hole in the trunk. Quote Link to comment Share on other sites More sharing options...
98LTZ Posted February 8, 2010 Report Share Posted February 8, 2010 My lumina doesn't have a low fuel light which kinda sucks. It has the red mark near empty. That's how I know how low I am. I got used to my previous vehicles with a low fuel light, but I try my best not to run it down that low becuase I just replaced my gas tank and i'm not trying to change the fuel pump anytime soon.

I didn't even know I had one. Mine must not work. your car illuminates the "check gauges" indicator. so do all other analog UB3 (full guage) 92-94 cutlass clusters.

WhatTheFehl Posted February 8, 2010 Report Share Posted February 8, 2010 I just generally go by the estimated range on the DIC. When it hits about 50 miles, then I get gas. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted February 12, 2010 Report Share Posted February 12, 2010 I would say it sounds like a cluster issue, the gauge test on startup just tests the lamps and gauges, but there could be a bad solder joint in the cluster that triggers the light to come on when needed Quote Link to comment Share on other sites More sharing options...
Twenty Posted February 12, 2010 Report Share Posted February 12, 2010 I always fill up at half tank and I reset the trip meter when I do. That way, there's always at least half a tank in the GP should I need it, and if the fuel gauge fails I have a back-up. A surprising amount of the time traffic jams here will be caused by someone running out of gas. I can't help but laugh at them when it happens.
