I have a 1987 turbo . I have removed all the emission crap as well as the choke butterflys and some sort of rats nest of fuel line. My problem is when i put battery power on the car the anti theft box went up in smoke, literally.cooked my main fuse too needless to say. after removing the box everything seems to funtion normally. However , i now have no spark at all. But I do have +12v to the yellow wire when the key is switched on. I am getting fuel and am not sure what to check next. Help please ?
