Question about 2004 Pontiac Bonneville

Fuel gauge seems to stick -- irratic readings

The fuel gauge on my 2004 Bonneville seems to stick. It gives bad readings most of the time. In fact, when the ignition is turned on, the gauge needle will sometimes stutter as it attempts to go all the way to the right, then back to the left and then settle on the correct fuel level. Many times, it just stops part way across the dial -- and sits there.

That's not a real hassle for me -- because I drive the car from full to empty, before adding more fuel. I know I can get 400-425 miles per tank, so the trip-ometer is what I use to gauge the level of fuel. BUT, I plan to give the car to my daughter this coming year. I don't want her on the road, not knowing when the car will run out of gas. That is NOT an option.

So, what can I do about the fuel gauge? Is there a way to "oil it"? If so, can you point me to some instructions for getting to the needle? Remember, when the needle doesn't stutter/stick, the fuel gauge reads fine -- and it always "tries" to do it's reset thing at ignition.

    Any takers? I supposed the entire gauge cluster could be pulled and oil applied to the needle spindle, but that seems rather complicated for such a small problem. I'd love to have other ideas!

    Same problem. Fuel gauge is stuck on 3/4. Never moves. Have heard this is common on GM products. Was advised that a new instrument cluster would be required to fix. Don't know $$ cost.

    Temperature guage in same vehicle is faulty. Stays "pegged" in the dash most of the time.

I've researched this problem thoroughly as all of my gauges on my '04 Bonneville GXP are producing erratic readings. The only two solutions are to replace the entire cluster which can cost in excess of $700 or replace the six "stepper" motors behind the cluster. Replacing them can only be done by deslodering the old ones and soldering in replacement ones.

My 04' GXP has a stuck fuel gauge as well but the digital miles left still works. A mechanic indicated that it could be the sending unit which is part of the fuel pump or the instrument cluster. It was suggested I utilize the digital "miles to empty" and wait a few months to see if any other gauges fail to identify the problem .

I just responded to two temp gauge problems; it looks like the analog gauges in your cars were poor when they left the factory. This makes 5 gauges, 2 temperature, three fuel gauges with all the same type of problem and oiling them is hardly possible and likely ineffective. Most gauges (they are really meters) that are subject to any repeated abuse (vibration) are of the 'taut band' variety anyhow and these are very rugged and are 'frictionless' movements having no pivots at all. And people wonder why the Asians are doing well while US car makers are dying?

Why is gas gauge not working correctly since fuelpump was replaced.

Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

Fuel gauge reads irratically.

This issue is almost always the sending unit, in the tank. Test that, which is easier said than done....You usually have to drop the fuel tank for access.

2005 Bonneville: gauges not working correctly

Hello blackbearwhi,
I have repaired many GM instrument clusters and without question your issue is a failed instrument cluster. The particular item that is giving you the bad gauge readings is the stepper motor that drives each gauge.
Please visit my website for complete repair information.
Thanks Mike

I have fuel pick up problems on a 1995 bonneville....gas guage says 1 quarter tank of fuel

I believe that the fuel pump and gas gauge are all one. They are located in the fuel tank. When they start going bad they sometimes start reading the amount of fuel left in tank incorrectly.

My gas gauge doesn't work in my 2003 bonneville. What can i do to fix this problem, along with my broken gas gauge my heater in my drivers side seat is no longer working, i would appreciate any help thanks...

It might not be anything wrong with your fuel sending unit. Keep an eye on your other gauges. I own a 2004 Pontiac Bonneville GXP. All of my gauges have started acting erratically. It started with my Temp. gauge, moved on to my speedometer, and now my oil pressure , fuel level and batty volt gauges are affected too. Its a very common problem with GM vehicles.

Fuel reads empty at all times

this problem is caused by a defective fuel gauge sending unit, this sender is located inside the fuel tank and is sold with the fuel pump assembly as one piece, around $200

2004 Bonneville - Temperature Gauge is Erratic

Since there is no voltage applied with the ignition off, if the gauge is not dropping down all the way, it is the gauge that has failed.
Temperature sensors are frequent failures but they are not active when the car isn't powered up. They can be intermittant, high, low but with no power, the gauge itself should go to the minimum.
