After driving my new rebuild for about three hrs yesterday the car started to shut off and all the electronics started to go weird. We also noticed the smell of something burning, like electronics getting hot. We turned the car off and to try and find the problem then it wouldn't turn back on. For some reason it will only start with the e-brake up. As soon as you put the ebrake down or slightly press the brake pedal the car shuts off. What could this be? What should i check? Any help please. Thanks
