It won't fix your electrical drain, but it will be much faster when you do get it started...lol But if you want to fix it, see the link for checking for a battery drain. It's not difficult, basically you hook your multimeter between the negative battery cable and the negative terminal of the battery. Wait a few minutes for the modules to shut down, then start pulling fuses until you find the issue. If you pull a fuse and nothing happens, then put it back and move to the next one. That way you don't pull all of the fuses then try to remember what fuse went where...lol It works best with two people: one pulling fuses and the other reading the multimeter display to see if it had any effect on the drain.
