The fuse (inside) is a 15 amp and is "for" I.G. Coil?Meter. The protected circuits should be: Ignition coil,distributor,fuel gauge, temp gauge,fuel inj. controller, indicators,oil/temp/fuel/brake/charging/fasten seat beltx/check engine/four wh drive.

Turn the key to ON/Run and the fuse blows right away. Can't figure why at least some of the things it supposedly controls don't quit working. Fact is a good many in the above continue to work. Car cranks, but fails to "start" and keep running. The blown fuse obviously keeps it from running. Haven't been able to determine if it's The ignition system or fuel system that is the culprit.

How does the fuel gage, temp gage, 4WD light, etc continue to work if the fuse is blown, or not even plugged in?

Presumably you bought this car used? Who knows what a previous owner may have done? The ig-coil fuse operates daytime running lights (if you have them), fuel pump relay, alternator, ignition coil, instrument panel gauges, instrument panel indicator lights, main relay, noise suppressor, o2 heater, auto tranny stoplamp switch and warning alarm controller. Exactly what continues to work? In any event, you will need to check that black/white wire circuit to find out where your short is. Fortunately for you, this is not an intermittent short, which would make this situation even more of a nightmare.

Put a test lamp across the removed fuse. I'd expect it to glow bright if a fuse is blowing.

Disconnect things until the test lamp stops glowing. (Or glows a LOT dimmer.) That is most likely your problem.

The test lamp provides a load to reduce the current enough to keep it from burning anything up. but if it makes you feel better, put a fuse in series with the test lamp.
