Fuel guage

I currently have my fuel guage out of my car, is there a way to test it to see if it works?

Depends on what your testing for... See Tomohawks thread above..

and check out the link... again I have no first hand experience with testing, or calibrating the fuel sending unit, or gage.. but it's a starting place..

my guage doesnt work at all. I was just wondering if there was a way to hook it up to a power source to see if the guage is the problem or is it something else.

Try these two seperate tests for sending unit then gauge.

First, test the sending unit.

1) Disconnect wires from tank sending unit.

2) Set your multimeter to the resistance function.

3) Connect meter leads to terminals of sending unit.

4) Move the sending unit float arm through a full swing.

5) If your multimeter detects a change in resistance during the swing, the sending unit is good.

Second, test the gauge.

1) Check for power at the gauge (key on).

2) Check for good grounds.

3) Turn key to ACC or RUN postion.

4) Install jumper wire across terminals of sending unit while having a helper

watch the reaction of the gauge.

5) If the gauge needle moves across the full scale then gauge is working. If

the gauge needle didn't move then its a wiring problem or the sending unit

is bad.

Obviously you must remove the sending unit from the tank to test it so I'd probably check the gauge first.

Much luck to you.
