Gas Gauge Drops to Empty?

I started my car this morning and everything was fine. I drove about 10 miles and parked for about half an hour. When I started my car again, the fuel gauge rose to full (I'd driven less than 20 miles since the last fill). When I was pulling away from the parking lot, the gauge dropped to empty and the gas light came on. After a second, it then bounced back to full. A couple seconds after that, it dropped to empty again and stayed that way. The SID said my distance to empty was "--- miles." I pulled over, turned the car off and back on again and the gauge was fine for the rest of my trip. This is a 2004 9-3. Has anyone else seen this? It was cold this morning (-14C), if that matters.

Shane,

My car ('04 9-3 Arc) did the same thing yesterday, and the day before. On my way to work, I stopped by Just SAAB Dayton to see if they knew about this problem. In less than 45 min I was out of there, and on my way to work. They had to unplug the power cable to the gas pump-float (I don't know where it may be located, but they had my car on the lift), cleaned the wiring harness connector, and then put it back together. That seemed to fix it the problem with the gas gauge. Good Luck!

Looks like I'll be taking a trip to the dealer pretty soon. Thanks for the information.

Does the wiring harness have a GM part number?

C900s do the same sort of thing. Contact cleaner usually fixes it unless it's a failed earth inside the sender. Then you need a working odometer or a good memory and a fuel can ... just in case! Cheers

Really? I have been driving C900s since 1985 and never had this problem. I had a fun drive home from work today - open country roads and a C900 turbo :-)

I'm driving an '86 c900 with this problem. Where do I spray the contact cleaner, please?

Pull out the cover in the boot (trunk?) that's over the sender. There's a spaghetti set of terminals with about 7 wires (5 going right and two left from memory - it's ten at night and I'm not going outside in the rain to check!) Spray the lot. If that doesn't work, note down where all the wires go (did it *2nd* time), carefully pull the sender unit out and give it a few firm but careful shakes to see if there's any crap to dislodge. Replace, add wires and hope Murphy is having a holiday - else get another unit from the wreckers! The only one of mine it *hasn't* happened on is my current v.cheap 81 900T 8v. Cheers
