Help: Fuel Gauge Problem
- Thread starter Randy822
- Start date
i think mine just started doing this the day i pulled it in to pull the motor gauge was on empty and fuel light was on and i had filled the tank (of coarse....they never go bad when the tank is empty) a few days before that,i asume its a bad ground or something ill have to run the tank down a little and pull it and check some of the conections,could be a bad sending unit too.My 2002 Silverado 2500HD Duramax fuel gage periodically goes to empty even when full and the low fuel light comes on. Any help may get me off Prozac!
Fuel Gage
I did find a mechanic on The Diesal Page who suggested I ohm connector C-152 first with a reading of 240 when full and 40 when empty. I will do that first. I may then run fuel out as much as possible, drop the tank and see if I can clean the sending unit and then move the float up and have someone ohm that connector while doing so. I called O'Rielly and they only have access to the entire unit and it's over $400.00 I will post further info on success and process when I get around to doing something. My problem is that this is my main work truck and I need it almost every day.

Mine did that in a gasser I had. At first sporadic and then almost always empty. Had to get a new sending unit. There are little "fingers" running across an electric strip they had worn off enough that they weren't touching properly.
