Re: fuel gauge
Hey '83B, wouldn't your 83 have a carburator and a mechanical fuel pump on the block? If you have swapped in a later engine and pump setup, forget what I'm saying. Otherwise, I think I'd check gas in tank to see if gauge or sender went. If it has enough gas, I'd check fuel filter, and do a pump-output test into a can (remember to disconnect coil to distrib wire, and short coil output to ground with a clip lead for safety).
Also, if you can see gas spray when working throttle linkage (accelerator pump) while looking down carb w/engine OFF, that tends to be a good sign, but still could be restricted by dirty filter. If you have a V-V carb, carefully open the venturi by sliding it back, to see down to where accel pump sprays out. Usually can get a couple of full strokes of gas out of the accel pump before the carb bowl runs out of gas.
