2000 sl2

2000 SL2 with 105,000 miles. Would not start, sprayed chemtool down its throat thinking the fuel pump or injectors were bad. Still no start. Cars computer was hot!!!!!!!!! So hot you could not touch it. Tried scanning the computer, but could no link up with it. Let it set til Monday, battery was down, still felt like at this point could be the computer, but thought I would look a little more. Got the idea to hit the gas tank, so then when I put jumper cables on it the car started. Ran it for almost an hour, computer did not heat up, ran great. Now the battery was down so I checked and I have a short. Still think it might be the fuel pump. It is not a direct short but I check it with an ohm meter between the body of the car and the positive battery cable bingo something is touching somewhere. Now, I can pull the massive fuse under the hood for the fuel pump, and it will register, but it will register on both sides of the fuse. I have the fuse out at this point. Pull any other fuse it will show on the meter, only on the battery side of the fuse box. Not the other. Which seems normal with a short. Anyone know how or why I can have a short on both sides of the fuse box on the fuel pump fuse? Also I have pulled the pump relay and the other 10 amp pump fuse. It makes no difference. And the scanner will link with it now, no codes. Any ideas????
