It recently has not been working. Used to be intermittent, but now it doesn't work at all. Way past full, at about 3:00 on the gauge, which would indicate ground, I think. Since I won't have much time in the near future, could someone please give me a starting point? If this is a common problem on these cars, which end should I start at? Gauge cluster or tank? Just need to be pointed in the right direction to start. I believe it's a 90 ohm sender, correct? Thanks guys.
