My fuel gauge is not working, does anybody know what the ohms are for the fuel sending unit so I can check it, also is there a float in the fuel pump that sends signals to the gas gauge. I checked the wires from the sending unit to the gauge and their fine, it could be my gauge and if so, does anybody know what after market gauge I can use with a gauge pod. thanks for the help

 

The sensor range is from 7.5 Ohms to 327.5 Ohms, depending on how much fuel is in the tank. The fuel sensor is not in the fuel pump, it is its own unit and it is located next to the fuel pump, more toward the center of the car.

Depending on the year of the car ('93-'95) there are diagnostic test you can run on the instrument cluster from socket A-7.

Its a 95 850 turbo, how do run the test, or how would I find out the info. thanks

 

Grab a copy of the factory service manual from here:

Once you unzip it see the file named instrument panel.pdf. It will guide your through the test procedures.

thanks

 

I just found out that I have a open circuit in the sensor,a code 113 does that mean I need to replace the fuel sending unit, or what does that mean. thanks for the help

 

Likely it does, I sorta fixed the one on my daughter's Porsche by cleaning all of the tar of of the nichrome wires and cleaning up the contacts with laquer thinner but its problem was that it had 8 year old gas in it when i bought it and the whole sending unit was a giant tar ball. Here is what I was dealing with:




In your case I think I would check salvage yards for a replacement and pick up a newbase seal.
