See if there is any clicking from a relay either if you remove the positive/neg terminals from the battery to indicate something being on.
If it's a wire grounding out somewhere than your in for a long night.

there is a clicking under the hood when I put the negative cable back on. At one time I have the kill switch to the car won't start position. Then I put it to the car will start position after I put the negative cable back on and the relay next to ECU start clicking until I had to switch the kill switch again.
