okay heres a puzzle for you guys, i have had my 90 z NA for about 4 months, i got the car not running with a no spark issue, and low compression in some cylinders, so i did a vacume test and found out it was one side of head so i replaced the whole head i also replaced the other side, so i got it back together compression is great, still no spark. so i replaced the crank angel sensor, still no spark, then i checked the ptu it was bad and so i replace it to, and yet still no spark, it turns out it was a bad conection to the ptu and no i have spark but the damm thing still wont start, i have fuel,air, and now spark what gives?!?!?!?!
