#20 of 29 Problem with gas guage. by gotgoldfever

Mar 05, 2008 (4:13 pm)

My gas gauge does not work. It never goes below about 3/4 full. If I fill it up it reads full and then slowly goes down to 3/4. Some times at idle the needle will suddenly swing from whereever it is between full and 3/4 to empty. Is it the sending unit, the guage, or do I have a short or something? If its the sending unit has anyone ever replaced one? Any words of wisdom in doing so?
Thanks!

After further research this appears to be a pre-cursor to the in tank fuel pump going bad. The fuel pump and sending unit are in one assembly. Ok time for a rant. I have less than 100,000 miles on this truck and I have replaced the uper and lower ball joints, the cv joints are bad and this fuel pump problem seems to be a known issue - happens on all these trucks (btw a new fuel pump is over $300) I have had two Toyotas prior to this truck. The first one had 350,000 miles on it and all that ever needed to be replaced were the brakes and the clutch, the onther one had 150,000 on it, nothing ever wrong with it and I traded it in on this piece of crap - wish I hadn't. GM wonders why they are not selling well.....

The gauge sender can be replaced, about $30 for the part.

yeah but why would you only replace the sender when you have to take the freaking bed of the truck out (or the gas tank which is worse) to get to it and since its an indication that the fuel pump is going bad?

Well I just leave the bed on and jack up one side, any ways I'm cheap.
I don’t understand the analogy, if the sender is bad the pump is too, never heard that one before.

I have a 99 GMC Sonoma. All my gauges work minus the speedometer/odometer. The odometer does display however, just doesn't move. All my fuses are good. It occurred after putting back in my factory radio (on the same day.) Guessing it had something to do w/it.
 
Any ideas??

Saw where you had the same problem with speedometer on your 99 Sonoma after putting the radio back in. Can you please let me know if you were able to find out what the problem was? Thanks

I got almost the same problem. Mine is showing 1/4 when its full. Pulled the bed off and pulled the pump out. Hooked a volt ohm meter up to it. When the float is down(empty tank) 0 ohms. When the float is up ( full tank) 100 ohms. My "Haynes" repair book says this is good????? Fun of it, I replace the fuel pump with a new one. Same thing. Whats up, where do I look next.
