Default Weird!! Gas Gauge issue

I just got gas, (Not Shell!) and right after I turned my car on the needle went down to empty and stays there. (had been on about a quarter of a tank). HUD and DIC indicate to check gauges. When I turn the car off and on, it moves to about the halfway mark and goes back down. Yet another electrical issue. Help always appreciated.

This sounds like the classic Fuel Level Sensor failure, which is not unusual on these GM platforms. There is a resistor pack (variable resistor) integrated into the Fuel Level Sensor that fails which more than likely is causing your problem. I think on your class of Bonneville, they will have to drop the fuel tank, pull the sender assembly out to replace the level sensor.

Not a failure. No problem. If you top of, this is likely to happen, and can randomly happen if you don't. Turn the ignition off, then back on, and it should be fine. Mine has done this every month or two at least once since I've owned the car. I can MAKE it happen by topping off too much.

(I don't have much control over this......we don't pump our own gas in Oregon).

Most rednecks are too dumb to pump their own according to the State Legislature. I hate it. I usually get out of the car and watch while they pump. This is one of the reasons Oregon gas is near the top of the price list usually. More employees.

Remember this when you come down in July. You don't want to look the fool!

Ok, I must have jumped the gun. My interpretation of the post was maybe the early stages of fuel sender failure.

Mark, I think it'* just a simple case of the sender being stuck too high for the reading to make sense to the cluster/PCM. Simply burning off some fuel, then cycling the ignition might help, too.

This is only the second car including my own that I've seen this on. Might be exclusive to 93'*, but too small a sample size to know for sure.

92'* were prone to an inaccurate reading. Different issue, I think.

Well I've driven like 20 miles and tried cycling the ignition. Now the gas gauge will go to Full right when the key is turned on but then goes back to E. Does this sound like that other issue?

92'* have like no baffling compared to newer ones, and that also causes their killing issue,

Topping off after the click, has proven to set codes off. I don't see a point to topping off, you'll never use it, and it stops for a reason.
