Anyone ever have intermittent problem with a msd box it seems mine will work then I shut the car off and it wont start back up. Also it will just die and not wanna start and then all of a sudden it works again.I have double checked all conections and wires. I just wanna know if the box could be defective.cause im getting sick of messing around with it. If I unplug it and run just off of coil car fires right up. This is on my 90 turbo fox.
