I am working on installing a autometer fuel level guage n my 93 coupe and I have three pins to connect. 1. Ignition 2. Signal 3. Ground. I tapped into the ignition wire and have that solved I have also grounded the meter as well Now, I went behind my instrument cluster and cut the fuel wire on the 13 pin connector for I can receive the signal. Currently the guage works sometimes and tonight when I got gas, the guage was reading close to empty, Now I know gas is expensive but the guage is reading incorrect. I have already made sure the guage is working correctly through a trick that autometer sent me. Can anybody provide some insight on how to fix the guage to read the correct fuel level? Or another way to get signal from the fuel tank? Thanks

 

anybody???? I could use the help so ensure I don't run out of gas when I am out of town. Thanks.
