What's with the fuel guage?

Good luck!

 

thank you guys im gonna get some techron tomorow hopefully at wallmart and start using sunoco ONLY like i was going to originally!

 

 

If you are going to Walmart...
buy Berryman's Chemtool B-12
It is reported to work as well as Techron for this problem.
AT THE SAME TIME
top up you tank with a premium fuel that is on this list

My fuel gauge stayed on empty until I cleared a PCM code. I have added Techron so hopefully the problem won't repeat.

 

 

Buy a couple of bottles of SEA FOAM (most auto parts stores carry it - $6.99/bottle - white with red writing on it, very plain). Go to a gas station that has top teir gasoline - CHEVRON, SHELL, 76, PHILLIPS 66 are a few. Pour the entire bottle into the tank and then pump it up. Do this one or two more tanks and it should clean the sending unit up a bit. This worked for me when my car did this about 12 months ago and I have never had a problem since. I also run a bottle about once a month.

Here is a link to top teir:

Here is a email I got from SEA FOAM:

Believe what you read in our literature and on the www.saefoamsales.com web site, it is truthful knowledge backed up by 66 years of customer satisfaction. Sea Foam, Trans Tune & Deep Creep are 100% petroleum oil blended product! NO CHEMICALS, so there is no danger of damage.

The number one use of Sea Foam Motor Treatment is in a fuel, be it gasoline (any brand or grade), gas/oil mix for 2 cycle applications, or diesel fuel.

Sea Foam used 1 - 16 ounce can to a minimum of about 8 gallons fuel, or a maximum of 25 gallons of fuel, is by design an added upper cylinder lubricant, moisture drier, carbon cleaner, fuel system residue cleaner, and fuel stabilizer (for up to 2 years at one ounce per gallon in most applications).

Other every day uses of Sea Foam Motor Treatment include:

1. In the crankcase oil ( including SYNTHETIC) as a pre cleaner to doing LOF service, an after LOF service additive, and a problem solver (or diagnostic tool) for other oil residue related crankcase system problems including sticky rings, lifters, etc.
Use at 1 1/2 ounces Sea Foam to each quart of crankcase oil, and give it a minimum of 30 minutes normal driving time before an LOF service or as a problem solver/diagnostic tool. Sea Foam works at making old oil residue back into liquid, so it may flow and be filtered. As an after service additive, Sea Foam works to liquefy that really tuff oil residue, and helps your oil keep from forming residue.
Like any other hi detergent oil product, Sea Foam may make your fresh oil get dirty, faster than normal, so monitor your oil for color and clarity at either mileage or time intervals, and change your oil when it gets dirty!

2. As an upper cylinder carbon cleaner, putting Sea Foam Motor Treatment in your fuel system will clean carbon off valves, cylinder heads, and pistons, AS YOU DRIVE! How long it takes will depend on how much carbon is present, how much product you use in your fuel, and your driving habits.

SO:

Sea Foam is used as an upper cylinder carbon cleaner by professional technicians who need "instant results" and also need to solve drivability problems that are carbon related. Simple to use on most vehicles, Sea Foam Motor Treatment can be used in conjunction with commercially available professional equipment designed for this service work, and can also be used by the "technically knowledgeable" DIY'er without special equipment. A thorough knowledge of the vehicle/engine induction system is required for using on EFI, TBI, and other "non traditional" induction systems.
Sea Foam Motor treatment is also used by professional technicians in equipment designed to clean fuel injectors at a 50/50 ratio gasoline to Sea Foam.

As for the other uses of Sea Foam Products:

Sea Foam offers its Motor Treatment in a spray can called DEEP CREEP, for ease of use in safely cleaning throttle bodies and EFI air inlets using a NON CHEMICAL, and in places where a spray might work easier/better than the Sea Foam Motor Treatment liquid. (small engines, side or updraft carbs, lubricating, cleaning, penetrating)

Sea Foam also offers TRANS TUNE for use in any hydraulic OIL, as a residue cleaner and moisture drier. Such systems include power steering, automatic transmissions, pump/plow assemblies, log splitter, etc. Again, 100% petroleum oil blended, TRANS TUNE is not a stop leak, but a cleaner and moisture drier.

Sea Foam also offers BUGS B GONE, a water based soap product for cleaning anything organic off any surface.
Bugs, molds, mildew, dirt, light oils, brake dust, road grime, etc. SAFE, it won't take the wax off your car! Use as directed, be creative, as a carpet/upholstery cleaner it can't be beat!

Hope this all helps!

ty everyone i was able to fimd the berryman for $3.50 at wallmart filled up with sunoco 93 and poured it in so far so good thanks again for all your help, bill

 

if its to late, seafoam or none of that stuff will work. if you have a pre 2000, your sending units have failed. its a common problem. mine, even with a full tank, will read half tank and then drop to E.

sending units are fairly expensive. dealer wants like 900 for both, PLUS 4 hrs to install... BS... i bought mine off the forum and will install in a few weeks. will let you know how the install goes!

Happens to a lot of C5s. Could be the type of gas you are using - if high in sulfur content it tends to mess with the gauge. Try running a bottle of Techron through the tank and see if it goes back to normal.
