Something's not quite right --- either high internal resistance (check with an ohmeter -- anything higher than 1.0 ohms (primary) and 11,500 ohms (secondary) would be a problem) or something nearby (e.g. distribution, associated electronics) is shorting/failing thus causing it to pull high battery current.....
It may be normal with your type of ignition. Just unplug the Ignition Control Module (ICM) while you have the oil switch jumped and working with the fuel system.
