Gas gauge not working

[HPG]

Does it ever end. Yesterday, I had a ½ tank of gas. Today the gauge shows full. I know the gas ferry did not fill it up for me at $2.15 a gallon. What could be the problem. Thanks for any help.

There is a J-connector at the fule tank. Have someone push, pull squeeze it while you look at your fule gauge. See if it's in the wiring at the connector, if not, then two senarios, your fule gauge sender has gone south or it's the cluster.

In the meantime, set the trip odometer to zero each time you fill up.
This way you will at least know when you need gas.

In my area (PA) there have been a lot of problems with gas gauges on injected cars reading full when they were not full over the last week or 2.

A Marathon (almost positive on the brand name) distributor has admitted selling tainted fuel that looks like the source of the problem.

Don't know if your problem is related to that but if it is they're taking information at the local attorney general's office. See if there are any similar problems in your area?

You just reminded me that last week, I pulled the spare tire and cleaned out the area. Could I have hit the connector, where is it located. Idid hose out the area as well.

Yes that may be the cause... You should not even breath heavily around your car...

What am I missing here? The gage will read any liquid in the tank. Whether it be water, gas, mercury or tonic water. Disconnect the wire from the sending unit. The gage should read full. Ground the wire (be sure of the wire you are grounding) and the gage should read empty. If it does on both accounts the problem is in the sending unit. If it does not, the problem is in the gage or associated circuitry. I have a T-Bird and occasionally the gage reads full when I know it is not. I slap the hell out of the dash and the gage reads accurately for 5/6 months. (A bad connection in the ribbon circuit.) But this is with an analog gage. I do not know if the T/S procedures are the same for a digital gage.

I notice the same thing with my gas gauge. When I fill it up it seems to stay on the full section the longest then rapidly descends. The first time I noticed it was after I quit racing the red lights

Very cool, I was just about to post the very same problem. Unfortunately it left me stranded on the side of the road for 2 hours.

I was driving my Vette to church when it happened. My gauge read 1/4 full, so when my car started to sputter I thought the gas was bad. I made it out of town only for it to stop in the 5 miles between two towns. I was told that AAA was a worthless for roadside assistance, I guess I was told right.

I called AAA and they said someone would be out in an hour. An hour later, with my wife and I standing on the side of the road with my new (to me) vette, I called AAA to see where the tow truck was. I was told that there was a computer glitch and they canceled my call. It would take another hour until someone would get there!ad

I called a friend who going to meet me at church to tell him the sad story and he said that he would bring along some gas. He lives over an hour away from where I was stuck, and guess what, he got there before the two truck did! :eyerole
Sheeze, sorry about the tirade.

Anyway, I appreciate the troubleshooting tips!

I have a 94 and my Reserve is always on, So I guess I'll do some checking also to see if my wires are connected.

Folks, why are you making such a big fuss about this??? Just fill up your tanks whenever it is half full (or empty depending on your life philosophy) and enjoy your Corvettes to the fullest...


:cool

Keeping it topped off!

It may take a few extra trips to the gas pump, but guys (and gals too), you MUST keep at least 1/4 tank of fuel in these cars, because the fuel pump is in the tank!!!!

If you run out of gas, the pump can easily overheat and that's all she'll write. You're then into $78 plus a couple of hours to replace the Fuel Pump, and while you're at it another $14 for the fuel filter while you're at it, because you know the pump has pushed about half a bushel of garbage from the bottom of the tank up the line to the filter before it ran out of oomph.

The gasoline in your tank is what keeps the pump cool. If you suspect the fuel guage is faulty, fill'er up and keep it that way!

Speaking of fuel filters, anyone know the part number for the O-rings that go in the lines connecting to the filter or if there is any type of seal on the lines to the filter?
