I just got my 945 back from the butchers at the body shop. Paint is great at the front- makes the rest of the car look bad, but......
Now the gas gauge reads less than what the tank is holding. Depending on temperature, it gets more accurate when warmer, less when cooler. It makes no sense to me that a front end repair could somehow affect this, but is there a ground nearby that may have been loosened?
You don't want to hear about the AC condensor that was supposed to be replaced, but got a new coat of black paint (AC doesn't work) or the map pocket in the door that is now broken, do you?
Sorry, brickboarders, I had to vent and my wife is tiring of it.....
Any suggestions on the gas gauge would be greatlly appreciated.
Thanks
Mark

The sending unit in the fuel cell is your problem, not the paint on the hood. This is a very common problem to our 940's of that vintage. Sending unit is expensive (345$US), hard to remove too. That's the bad news, the good is it's very easy to check. In the ditch behind the rear driver's side wheel well is a four wire harness with a simple little plug in connector, two of the wires are for tank prepump the other two are for the sender to gage circut. Just unplug and jump gage wires, you should be able to see fuel gage on dash go slowly thruogh full-empty cycle indications, if so then look to the troublesome sender. If you wish I'll look up wire colors for you because I do not remember them off hand now.

Funny how coincidental problems occur after a visit to a repair shop. A part of me wondered about the age and float condition, and sitting still for 3 weeks. I looked in the area you mentioned and saw a 4 wire connector, but not sure if it's the correct one, or which direction to test. It seems to me that if I start jumping connections and inadvertantly jump the pump connections, I could do some damage somewhere. Also, my car is a wagon, if that makes any difference. If you get around to it, I'd appreciate the color codes, but no hurry. It's raining all day here and I know how much fuel I have.
Thanks,

I have fixed one and it wasn't easy. The whole unit needs to come apart. The dark brown tube (it used to be white) come apart and inside you will see where a finger rubs up and down on some coiled wire. The finger that make the connection is worn out and needs to be replaced. I used a finger from a Ford fuel pump and sending unit because it was there. Most fuel sending unit have these fingers that rub on a coiled wire to change the amount of voltage sent to the fuel gauge. Patience is the key. Solder a good end on to the existing end and there you go. Piece of cake.
