Hi,
If I understand correctly, he got it to start but when it shuts off, it doesn't want to restart. Is that correct?
If that is the case, then either we are losing the ignition spark or fuel to the engine. When it cranks and doesn't start, see if it will start if you use starting fluid. If it does, then we have a fuel related issue.
As far as a parasitic draw, if your battery maintains 12.39v, that isn't the issue. If there was a draw, the battery voltage would drop off.
Let me know.
