Looks like the battery must of knocked off the sensor that is right on top of the starter. Thats what happen to me when I had my turbo swap it wouldn't start.
nvm: I though ur battery popped off.
I remember 4 years ago at the Sema show, this guy was building MR2 intercoolers with passages. They circulated some sort of gas that would freeze them up real quick. I can’t remember the company name………. grrr
