My Gas Gauge don't not work at all.... Things that i though it caused: Gas Tank Sender Unit=Change, New 85 SR5 Gauge=Change, but it still does not work..! So now i'm lose and i need your help... The Problem is: the gas gauge needle moves to position when on Acc, but drop to "E" right after you put into gear... I know i got powers to the gauge but was it ground faulty or other? don't no... what do you guys think??
