fuel guage problem...
For the last couple weeks, my fuel guage has been acting strange. Sometimes, when I start the truck, the guage will indicate a full tank when it's not full. The overhead computer also indicates full tank mileage. I can kill the truck and restart it, and both the guage and computer will indicate correctly. It seems to be a fairly intermitent problem, so I am thinking it's a sending unit. Anybody want to second that thought, or give another idea??

You said it, Ken. I'd rather do ANYTHING than try and track down electrical problems, and from the looks of the responses (or lack thereof), most everyone else would, too!! I've got a dealership close to me that seems to be pretty good with the V-10 trucks, guess I might give them a call on this (last time I went to the dealership, it cost me a little over $400).

Since you're having trouble with both receivers, I vote with you on the sending unit.
I've seen a poor ground cause a false full or overfull (pegged) reading on fuel gauges. Have you checked all the wiring and connections including the ground?
I have had a similar problem with mine - I don't have a fuel computer just the gauge. Although it was very infrequent, I haven't seen it since I wiggled and CRC'd the wires at the tank about 3 months ago.
Just a thought.

I know this is a much over used line, and I know we are really enjoying the benefits of the technology that prevents us from working on our vehicles like we used to be able to.
But remember the old days ? When you could actually work on your car/truck ? Yea, yea, I know all the responses, we get much better fuel mileage, more horsepower, less emmissions, all that, I know all that, and I appreciate all that.
But I miss going to the parts house saturday morning with my dad and buying plugs, points, rotor, wires, a condenser, a distributor cap, a couple valve cover gaskets (or one depending on the engine), a case of oil, a couple filters and spending saturday tuning up the family wagon. Boy, when dad would let me fire it up, or bump the engine over to find top dead center, I thought I was the king. And when we got to where we were almost done and my dad would close his eyes and tune the carb and then tell me to rev it up, I was A.J Foyt coming down the straight away at the Indy 500.
Now we make an appt and it costs $400 for the dealership to find a short in the fuel sending unit,,,,,,,sigh,,,,,,,,,

I hear ya!!
I grew up building street machines and drag racing at a local track on the weekends. My summers when I was in high school, I lived at the track or working on my cars (when I wasnt flying or at an airshow). I was one of about 5 guys at my high school that others would actually come to when they needed help with their cars. I could just about tear down and rebuild a motor or transmission in my sleep, and then go out and win races with it. Heck, I was even pretty darn good at building and tuning Holley carbs, which is a dying art that seems to elude a lot of people who have a lot of experience. But now, I look under the hood of my big ole truck, and it's confusing as hell. You almost have to have a college degree just to get the valve covers off nowadays!!

And to me, the new stuff makes more sense than a carb does. I mean, it ALL makes sense, but a carb is just a lot trickier...
Wiggle the wires at the sender at the top of the tank. Trace them down the frame, if you can.
On my '01 F250, the wiring passing down the driver's side of the chassis was caught between the chassis rail and the cab! If I hadn't found it one day, I'm sure it would have turned into a nightmare.
