Wrong. Two separate circuits.

Cold solder joints in the circuit board is the reason the clock does what it does. Common 2nd Gen issue, easy fix.

I'm under impression that the fuel pick up is at the bottom of the tank.

So where else would you put the fuel pick up? :lol:
i appreciate the advice but - you dont think ive read the faq huh? i know about the cold solder joints. ive already taken it apart and repaired all the solder joints, and even tried swapping the idiot cluster out of my parts car. i know my own car, and when i hit bumps (or tap right above the idiot cluster) that happens. so if its not the idiot cluster, what else can it be? well lets see... the only plug on the back of it.

edit: sorry off topic.

I would think the bigger issue is that running on low all the time would cause cooling issues with the pump not being immersed in fuel.
i would think that this is the case as well. it wouldnt make sense to suck up the fuel from the top... but im not sure about this

edit: damnit already answered sorry guys

Mine works, now some other lights may not lol

On my 87 it worked intermittently. Then stopped working altogether.

On my 90 it worked fine.

On my two most recent cars (which i road race) i have no idea if they worked because i never run the tank below about 1/3rd or they fuel starve.

Brody8877 02-17-10 06:06 PM
mine works ¬_¬ but I rarely see it coming on, because I usually fill it up at half tank

DrKillJoY 02-17-10 09:11 PM
I usually fill up when I get to 333 miles a tank. :P
