engine can't start, starter motor doesnt seem to want to do anything, similar to an earlier problem I had with the starter motor only going after 2-3 ignition tries (which seemed to still be there when this problem arose, very harsh & slow start up, and in the extreme case it would die on me if I turned on the fan, other times all the electrical components would just turn off, etc.)... engine was off for 30 minutes at the most before I tried to turn it back on... what the deal?
