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
