Fuel Gauge Problem
#1
My fuel gauge stopped working three days after I picked up the car. Every now and then it will work for half a day or so. The car has been in to the dealer for repairs and still does not work. Here is what they have done so far:
First trip, they put an addative in the tank and said to run BP gas for 3 tanks because of the TSB on the corrosion on the sending unit. Did not work.
Second trip, they had a conf call with some engineers in Detroit since they could not figure it out and it was decided to replace the fuel sending unit, and it was orderd.
Third trip, they replaced the fuel sending unit, and the gauge worked for half a day. They are suppose to get back with Detroit again.
Also, they said they tested the gauge and it works fine.
Has anyone had a similar problem and if so what did they do to fix your issue?
Thanks!

The sensors in the gas tank where cleaned twice. After my third visit I was told to use Chevron Techron. I have not hand any further problem with the gas gauge or sensor unit.

I am surprised that Ford hasn't fixed the problem yet. There was a TSB on them back when I got my 05GT. The gas gauge went out and there were filler problems. They ended up replacing the whole tank including filler and sensors. It would set off engine codes when the gauge would read empty. I would suggest checking for TSB's on the matter on NHTSA site.

I had a problem with my gas gauge today, for the first time. This morning when I left the house I had over a quarter tank of gas. It's a 5 mile drive to work. When I went out for lunch, I started the car and the gauge was on E and the counter said 0 miles to empty. I thought somebody siphoned all of the gas out of my car!
I went straight to the gas station and filled it up (took 10 gallons). I realized at that point that the gauge was wrong. Once I restarted the car it was fine, and has been fine since.
The GT has sat for the last week or so, and the tank of gas has been in it for almost 3 weeks. I don't know if that could have something to do with it. We've had such good weather that I've been sharing time between the '66 Mustang and my motorcycle!

Techron is available at most of your local Chevron stations. Both in the gas and at the counter in a 12-16 oz bottle.
Also some of the Autozones, PEP boys, Advanced Auto and O'Rileys carry it, at least here in Bama they do.
I have not been able to find it in Walmart or NAPA stores here.
The sulfer problem sounds like the same issue that the Texaco/Shell Stations on the Gulf here were having several months ago. Got more than Stang fuel sending units.

I was pretty sure I still had almost half a tank, but I went right to the gas station to play it safe. I filled it with about 9.6 gallons, which made sense, since the trip meter said I drove 172 miles since the last fill up. The message center said I had used 9.4 gallons, so that was ablout right too.
I figured there was a problem with the gauge. Either that or something was reset since I hadn't driven it for a while. Since that fill up, I haven't had that problem again. I filled it up yesterday, and everything was fine.
I didn't imagine a high sulfer content would cause this. I will keep an eye on it, and if it happens again, I'll try one of the suggestions here. Thanks for the info!

Issue: When filling from empty and with the key in the "on" position it will register at half a tank and 45 minutes later it register finally at "full"
Troubleshooting steps taken:
I have had my fuel sending units replaced with 2007 version, the engine management module has been manually reprogrammed. Detroit enginnering has been contacted and my car is still in the dealer as we speak. It has been there since Monday of this week. They also disconnected my after market alarm system to ensure that it was not feeding back to the smart junction box and creating a problem.(It was ruled out) They checked the gauge cluster and monitor the fuel level as it was filling and after doing all that, still no resolution.
I would appreciate any advise.

Wow...I know exactly how you feel with your fuel gauge. My 06 has been in the shop more than a few times for the same thing. The first time they replaced the two sender units per the TSB, the next time they found a short in one of them and replaced one of their new sending units, then they replaced two wiring components just recently. My gauge enjoyed going from 1/4 tank to zero very quickly and I was even stuck on the side of the road once because of that. My dealer was also in contact with the engineering department at Ford, but that got them no where. Amazingly, this past week, I drove 100 miles in 2 gallons of gas according to the gauge!
As much as I love my Mustang, I find it ridiculous that they are unable to fix this problem for some of us. First warning lights coming on for no reason...then my gas gauge not working for months...and most recently my electronic throttle went out as I was entering a freeway...fun times getting towed. Love the car and haven't done anything to it, but upgrade the wheels, so hopefully they fix it and I can get more stuff done to it.
