So I will assume you have spark, seeing how your questioning whether it's carburetor or fuel pump. With a mechanical fuel pump, the easiest way to check is to disconnect fuel line at carburetor, and aim it in to a pop bottle, or similar container. Remove connector at distributor so no spark.
Crank engine over and see if fuel runs in to bottle, or container. If good flow, pump is o.k.
The proper way would be to hook a vacuum gauge up to inlet of fuel pump and crank engine and note vacuum.

I would say that your wiring loom leading to the alternator could be shorting out either with moisture or by explosed metal of the cable through the car's metal work, It would be worth it if you are skilled in the use of electrical testing equipment (DMM)to follow continuity of resistance along the wires, although this will require having to make breaks in the cable or un attaching established connections, And/Or looking for obvious damage (frayed cables etc.) if you dont know what your doing then its much better to get somebody who does,
Hope this helps, Sion.
