I put a new gas tank and sending unit in my car last fall. Everything worked great except for it was not calibrated correctly. This spring I took ou the new sending unit and adjusted the float. All was well for awhile then the fuel guage would intermittenly stop working, go to empty as if it was grounded. Took out sending unit again and saw no obvious issues. Reinstalled and now it reads empty all the time, not just intermittently. If i remove the postive wire the guage goes to full. If i put it back it goes back to empty. Is there something on the sending unit that could ground causing this condition? I really do not want to buy another $75 sending unit. Any advice would be greatly appreciated

Thanks

Bob,

Your symptoms sound like the float is getting stuck all the way down, as in the empty position. If there is gas in the tank, see if you can unstick it by pushing up and down on the trunk area. It might work. The fact that the gauge works when you disconnect it leads me to this conclusion. If you have a multi meter, put it on the ohms scale, red lead on the tan wire (I presume) and black lead to ground, it should read somewhere around 0 ohms empty and 90 ohms when full. My guess is your is somewhere around zero due to a stuck float.
Good Luck. ITO

It might have been a better choice to have your original rebuilt...new ones are made in taiwan.

I am starting to think that as well. Too bad I tossed the old one.

Thanks

check the float to make sure it's not full of gas (if it's brass.) It will sink to the bottom. If there's a pin hole in it, you can solder it, or replace it. I would test the sender out of the car and see if it still goes to E when hooked up. You'll have to jumper to a ground from the sender housing. Good luck.
