'70 fuel gauge-weird problem

grumpuscreature said

If I understand correctly; if you start the car normally your gas gauge doesn't work, but if you back off on the key a tad after starting the gauge works? If that is the case, your ignition switch is worn out and you need to replace it. Sorry 'bout that.:sad:

Yep, you understand correctly! Thats it exactly. I was wondering if the ignition switch was THE problem.. There is a bit of sloppiness to it. Im not sure I understand why the ignition switch could be the problem, this had some pretty good people stumped on another MoPar website..

Just a note to the few other post: my gauges werent converted to 'Digital'. G-Car just converted a few of the gauges to solid state which is a pretty common thing to do nowadays. If I remember correctly, it does away with blown fuses..Im sure someone else could explain better. Anyhow, its confirmed, the gauges DO work properly.. Problem is isolated to fuel gauge droping to Empty when the engine is started.
